The sport feature with the +/- allows you to shift your gears rather than the computer. It's a super great feature because it gives the driver more control but can potentially damage interal components if not used safetly. The biggest takeaway is not to hit "Red Line" which is the red portion of your RPM's when using sport mode! Love to see more cars aquire that fun feauture
@@rammiq that's the manual feature, not the sport feature. the sport feature optimizes the shift points where the drive position tries to save gas at the expense of performance.
#6. When parking on a hill...first shift to neutral, then set parking brake, then shift to park. Now the weight of the car is supported by the brake not the transmission.
Shifting to neutral and the particular order does nothing here. The takeaway is to just both use the parking brake and shift to park whenever you park, on all types of surfaces and inclines.
#6: Get into the habit of using the parking break. You want to place the brake and then release the footpedal. That way the weight of the car is on the parking break and not on the transmission. This is very important on a hill, the car can jump out of the park position if you only use the transmission (learned from personal experience, family member was almost killed).
The transmission is made to hold the car still. It will not damage the transmission. It is made to lock the transmission depite the angle of the car. Emergency brakes vary and depending on the hill, if that's all you use, you may find your car at the bottom of the hill. A properly working transmission will noy "jump" out of park. You can tow an 18 wheeler using a large enough chain and the parking paw from almost any auto-trans.
@@jonblachley1911 The parking setting on the automatic transmission is often just a pin, its not designed to hold the car at an angle and it can jump out. Its also bad for the transmission to hold the weight of the car against that pin. By adding the emergency brake its an additional level of security (you still have the car in park after all, its not as if you can leave it in neutral) and its one that is better designed to hold the entire weight and not simply jump out. If you emergency break doesn't work, you need to get it checked. Perhaps big trucks have a more reliable design since they have to carry large loads, but you can't extend that to all cars. I can tell you from personal experience, I have seen a car jump out of park and it almost killed my brother. If he had set the brake, it would have been an additional layer of protection and would have saved him.
Fords, Audi’s, and some Nissans has issues with parked cars. They tended to roll out of normal park position and end up down a hill at full speed. The newer cars all have issues with “Sudden Acceleration“ and two of them are notorious, they are the following: 1)1985-2011- Audi’s all types. 2) 2000- present -Tesla’s due to Software Computer glitches. Most incidents still under investigation by the NHTSB, the DOT, AAA, IHSB, UK , CDOT The BEV are the most dangerous, they accelerate suddenly, hit a concrete pillar or highway speed obstacle and sometimes trap occupants and explode like a phosphorus grenade, water will not put it out, they have to use a chemical sludge gel that comes from certain marine animals, or they just bury it in sand to smother the fire but it still burns for a couple of days sometimes. Not do good for trapped humans or pet animals!
you forgot one very important thing and a lot of people ignore this; when your car is parked on a slop or hill it is imperative that you put the car on neutral and then put your leg/hand-brake, release foot from brake so that the cars weight will fall on that instead of the gearbox, once that's done then you can shift it from neutral to park. When this isn't done and it is put directly to park, when you are either reversing or driving forward, you'll feel a huge resistance or vibration /hear a thump in your gearbox. Anyone notice this?
And if you can remember it, turn your wheels inward or outward, depending on if you are facing up hill or down hill, in case something does go wrong or you car is hit by another car so the little bit your car may move, the wheels will hit the curb and hopefully keep it from moving too much.
BAD IDEA! Anything hanging from the mirror is illegal. This includes air fresheners, your baby's first shoes & other such items. You probably wouldn't get stopped for things hanging there, but in case of accident, it will be your fault & you could get ticket. The violation is OBSTRUCTED o r DISTRACTED VISION..
Don't forget if you're going down hill, and the roads are bad, you can shift to D1 or L to put it in a lower gear. This will prevent the car from speeding up too much, helping you keep better control of the car.
I shift to a lower gear range going down a long hill regardless of road conditions. I've heard from reliable sources that the rule is ' if you have to brake more than 25% of the length of the hill, change to the next lower range'. I'm often behind vehicles riding the brake down the entire length of an 8% hill that is 3/4 to a mile in length, this practice produces incredibly high heat in the braking components (my truck has 97,000 miles on the clock and still running original brake pads).
All the points made in this video are important. I would add a 6th. "Never allow transmission fluid to get worn down and degraded." The worn down and degraded transmission fluid will not properly protect the gears and other in the transmission. It's best to maintain the transmission at the recommended maintenance schedule of the manufacture. Few do this and the result is a worn down and degrated transmission fluid that is not able to continue to property protect the moving parts of the transmission.
I drove large cars for 40 years. Most had manual 10 or 13 speed Road ranger transmissions. However, in my personal vehicles, I preferred automatic transmissions.( 'cuz I ain't working when I ain't) Of all my automatics, I had one torque converter fail.
Exactly regular changes and after any overheating incident. Remember 99+% of autos use radiator based coolers( dumb design). Even though the trans temp range is well above coolant range it's always better to cool in ambient Temps than at 200 degrees.
Park or neutral is better than turning the car off. You want the engine running to continue to pump the fluid and cool the trans while its sitting. Otherwise you're just letting it heat soak.
@@harrygatto depends on the car and how you were just driving it. Hard highway running a couple minutes. Town driving maybe one minute. Turbo car a couple minutes to let the oil drain out of the turbo.
@@shadow105720 Turbos are off-topic as we're talking about automatic transmissions. In addition, you're wrong about why a turbo engine should be allowed to idle before switching off; it's to allow the bearings to cool while the oil is flowing and stop the oil from being burned into the bearings. Unless you want to explain how keeping the engine running allows the oil to drain from the turbo?
You have no idea what heat soak means. If what you said is correct then everybody heat soaks their engines. Heat soaking is when the engine temp doesn't drop after shutting the engine off. It either stays the same or goes up.
About #5, only put the vehicle in park if you are turning the engine off and setting your brakes. If you keep your engine running at a traffic stoplight or train crossing, best to just shift to N. There are incidences of distracted drivers who are at a full stop, engine running and set to park where they have their foot on the gas pedal unawares. Once they try to shift to drive, the high rpm from foot on the gas pedal causes engagement when it passes the R position, causing the car to reverse quickly, and as the sudden backward jerking motion of the car causes the driver's body to pitch forward in the seat, the gas pedal gets depressed more as the hand on the shifter is moving into D, which causes the vehicle to lurch forward and the driver to lose control due to disorientation.
I drive manual but learned on an automatic transmission, and I was told that also going in neutral protects your transmission and engine if you get hit from behind. If you put in park instead, you will definitely get damage to the transmission in addition to all the other damage.
Not for Nissan CVT (I had 2 Nissans, unknown other brands/CVT), Nissan CVT, N might be only good during towing, turnoff engine or P is okay (no N during temporary stop).
Thx a lot, i used to shift into drive without being completely stopped, I won’t do it anymore. But at one part you said it’s OK to rest your hand on the shift knob, on manual cars you’re not supposed to do that.
And this is why we have transmission coolers built in to the radiator and this is always why there’s a torque converter you shouldn’t have to worry about heat. I will agree stopped at a train put it in park I do this because my foot gets tired holding the brake.
But my car owner's manual strictly advise against this "Parking for a short time, place the gear lever at neutral gear (N) and pull up the hand brake. Do not press and hold the brake pedal in (D) or (R) even if you park your car for short time as this will impair the service life of automatic transmission"
@@steventan2550 yea but the engine at idle is a very small load on the transmission it’s worse to be on a hill with your foot on the brake because that’s putting a load on the transmission but it’s very little.
Also another reason not to use neutral when going downhill is that when gears are engaged, the engine will partially slow down the car (engine braking) and that will spare the brakes slightly. In fact if u manually shift to a lower gear (downshift), u will increase engine braking which will reduce the chance of brake fading or brakes failure and will increase the longevity of ur brakes when going downhill. But if u do that avoid shifting into 1st gear as that will significantly slow down the car and could even damage the transmission and engine. Also watch the RPM counts when doing this manually.
I would never put my car into park whilst simply waiting at traffic lights as going from drive into park and back again can cause unnecessary wear on the engine. Also, the driver behind you is more likely to think what is going on when he suddenly sees reversing lights on the car in front, however briefly that may be.
I agree, when the intention is to keep engine on. If the intention is to turn of the engine to save fuel, transmission in park is a layer for safety. The wear is not only on transmission, also in air conditioning + sound system + air purifier + whatever on, because it all need to be turn off. So when the engine is turn on again, electric doesn't get burden.
Number 5 is wrong, the slip occurs in the torque converter not the clutch on an automatic. Your transmission won't overheat from shaft speed mismatch in the converter, but your engine will be marginally happier so it is still a good idea Number 4 is wrong, unless your oil pressure gage reads low pressure you have proper oil circulation, hot oil runs like tap water. Don't put it in neutral going downhill anyway though because it is stupid (main reason not to do it) and actually wastes gas (in fuel injected engines). When rolling, the power input to the crankshaft rpm is wheel speed and your ecu will deliver less fuel, whereas in neutral, crankshaft rpm is determined by fuel air ratio (injection volume, or throttle clearance for carburetors) so your ecu will deliver fuel to achieve idle rpm to keep the alternator above 12.5VDC. If the driveshaft can turn the crankshaft fast enough to spin the alternator to 12.5VDC output without fuel delivery (typically 7.5 mph vehicle speed if in first gear) the ecu will deliver the minimum fuel to keep the engine running which is actually less than idle fuel injection volume. The difference in volumetric fuel delivery is about the same as the difference between a cold choked carburetor and a hot carburetor, but if you're shifting to neutral to save $0.12 on gas you might as well do it right All in all, good list, the reasons are just a little off
@@randalrhoades8482 because the engine is running unloaded. Rolling down a hill in gear requires no fuel to spin the engine, the driveshaft is spinning it
I used to have a Fiat Argenta automatique with a 2l twincam engine, my favorite trick was to rev the engine to 5000 rpm then put the gear select in drive 1, the back wheel used to spin on the road like a clutch until it got grip and the car shot off like rocket. It lasted for years and years.

You should always use your handbrake when you are parked, it's not an emergency brake !! If you don't use it on a regular basis it can seize up and won't be there when you need it !!
#1 depends on the circumstance. The engine will be fine if it’s still in drive since the clutch is in, meaning that the transmission is disconnected. It is basically like having the clutch in on a normal manual. I would only really do it for example at roadworks where you’re stopped for 10 20 minutes. What isn’t good is leaving the car in drive in any case or in park without the handbrake, which could cause major damage to the gearbox.
My idea for extending the life of an auto transmission is, as you accelerate from standing, and the transmission is shifting up through its range with increasing road speed, briefly lift your foot pressure from the accelerator just as the trans shifts to the next higher gear; similar to what you do when shifting a manual. This takes the load off the clutch bands momentarily as they are loosening and re-tightening, reducing wear on the bands.
@@horsepowerandtalk1033 The trick is to know when the shift is about to occur and anticipate the letting up on the accelerator. My Ford Escort has over 300,000 miles on the original tranny and it still runs quiet and shifts smooth.
@@antoniograncino3506idk about the escort but some other ford V8 models like the crown Vic already have that feature inbuilt to the transmission computer. Each time the tranny shifts the engine power is reduced for a second by reducing spark advance. So the car will do it anyway.
Thanks. Most of these things are common (technical) sense. But I found it useful to know why not to keep the car running in D when standing a long time. (Most modern cars now have a start/stop automatic.) Question: Why not put into N instead of P while standing e.g. to keep the heating on during winter or the aircon during summer. I wouldn't want to coast downhill in N anyway, as it is much less secure. Now I know there are also technical reasons not to. With modern e-cars and hybrids I would like to add, that often D is better than B. It might depend a little on your driving style, but generally speaking sailing saves more energy than breaking returns to you. Downhill it is another story where you can use gravity to charge your battery.
All good information for a lot of people son. I'M NOW INTO MY 55lth year of driving vehicles with automatic transmissions. I've never had a any of my transmissions to break, fold or mutilate ever. I do a every 3 to 5 year full service on my transmissions, otherwise I drive them similar to how I would drive a standard. I use my gears a lot. Current vehicle, has the TH 700 and I will shift to low ,like as I'm turning to run down the on ramp to the interstate or expressway. I run up to 45 at times "getting into it" to be up to speed limit when entering freeways I'm now in 2nd gear as I enter the freeway, then I cool it at 70 mph and shift into drive, then Overdrive..I also run through all my gears occasionally, pushing the tachometer up close to redline..1st 45, 2nd 95, 3rd135, and 4th 150+. and this car and transmission are all original, with 2002000 k miles. My work trucks all had me driving 10, or 13 speed transmissions, and why I never wanted a stick in my car. My first cars were all stick shifts, but once I started trucking. I preferred my automatics. ❤
I think the transmission gain (based on my limited knowledge of them) has drastically improved performance in the 90's changed the automatic side of things for the better.
Sadly even here in the UK we are losing the battle against the automatic gearbox, almost 70% of all new cars sold in 2021 were automatic Vs 15 years ago 80% sold were manual transmission, I have a manual car, but regularly drive a friend's sons automatic car and yes easier less to do but nowhere near as smooth and responsive as a manual car
this is so wrong. An automatic car, especially newer automatics are much better than any manual driver. During the 80s and 90s when cars were becoming automatic, sure a good manual driver was better than an automatic but nowadays there is no comparison. Its a better shifter than you, its better at fuel economy than you, and yes its smoother than you. Smoothness is definitely a thing when it comes to CVT. Hell some CVTs fake a motion for gear shifting since people don't like not having that. Unless this car is old, your friend's car is better than you. What you don't like is the difference and thats perfectly fine. You are just under a placebo effect. You are used to how you drive and how your car handles. And you don't like the difference in feeling. And since you don't like it you convincedd yourself its bad and thus its bad.
I have a Skoda Karoq 1.6 tdi. (VW technology). DSG automatic. Seven gears, smoother and quicker gear changes than any manual driver. Driving for economy and not exceeding 60mph, up to 64 mpg. That’s UK Gallons of eight pints, US gallons of seven pints=56 mpg.
Sadly the same thing is happening here in Australia. My mum wanted her new Honda Civic in manual and was told that they don't make them anymore and she had to settle for the cvt transmission. Over the years I have driven lots of things from road train trucks with 15 speed non-syncro manual boxes to the basic hilux manual boxes. Automatic gear boxes were a luxury back then. I still drive lots of manual things for work but my personnel driving car is an auto, it's a V8 and should, by rights be paired with a manual. I bought it second hand and didn't really get of a choice. As they say now a manual transmission is the new theft deterrent.
@@densetsu4286 not the case my friend's car is a 2020 VW and has a DSG gearbox and has awful gear change in the lower gears especially pulling away from standstill, and I don't know how you can tell me I am wrong have you driven this individual vehicle, NO you haven't, I like the idea of not having to change gears, I have never driven a CVT but have driven manuals, the old school and DSG autos and up till now I still prefer a manual as I still find them smoother to drive, and untill I drive something that changes my mind i will retain my opinion
Coasting downhill in neutral isn't wise, but it won't damage either the engine or the transmission. It doesn't matter if the car's going 35mph and the engine's idling, the engine-driven oil pump will provide lubrication to the idling engine. In a true fluid automatic the torque converter is basically a big oil pump which drives the transmission. If the engine is idling it's still spinning the converter, which in turn is pushing fluid around the transmission. The advice is the same in a manual, not to coast in neutral, but with either type of transmission the only reason is for safety, in maintaing full control of the vehicle.
Ya fer sure. Engine oil pressure has nothing to with in gear on not in gear. Oil pressure increases when revs increase weather theres a load on the motor or not.
An idle engine might provide enough lubrication on perfectly level ground sitting still but going 45 around a corner probably not. Some cars stock oil system cant even cope with that normally for long periods of time. They're made to a bare minimum.
The last one is not 100% true on all trans some have if I’m correct all have a separate reverse gear that has different gear threading made to go the opposite way and all the other gears are disengaged when reverse is activated
also this tip does not 100% apply to oil transmission types. (I don't know its English name, but in it, there is one gear that spins oil and another gear that gets its spin from the oil.) Some car manuals even tell you to shift from drive to reverse without breaking if you get stuck in mud or snow. But I still would recommend following this tip, coz it really does wear your transmission, even if it was designed to withstand it.
@@esa689 true personally I will go from reverse to drive but I let the car naturally slow down reversing while I’m still breaking before I hit the gas to go forward even tho it’s in drive because that’s where it would cause damage and wear
As a ASE MASTER TECH The part of shifting to neutral at a long stop was maybe a good idea but since the modern electric shift /pcm controlled a pintel reduces / loses pressure to the 1st gear clutches doing this for you it instantly closes on throttle movement & brake release ,possible a few truck models don't though You need to use manuf. ATF Fluid only as they all use a different friction modifiers That can cause the disks to wear & grab , or slip heat up more without
When I was learning to drive (UK 1970's) my instructor had a student who accidentally put the car in reverse at around 35 mph. result: 1 trashed transmission.
At 16 I thought it would be a good idea to shift into low to go up a hill. Owner of car sitting next to me and my Dad in shotgun seat, all three front seat. 1958 Buick. When I pulled the shift lever down to where I thought low would be the rear tires locked up, going about 25 mph. Dad started hollering, George did not say anything. I calmly put shifter back to drive and continued on with Dad asking me what I was doing!? Anyway, taught me a lot of lessons. The car was just fine, good old American Iron.
Thank you for the lesson! I learnt not to change the gear abraptly cause it might damage the gears esp from drive to reverse... I guess I do that a lot...
Resting your hand on the gear stick is a very bad habit and you should get out of that. Another good practise habit to get into is to let the engine achieve normal idle speed before putting it into gear and driving away. This allows the oil to circulate completely ensuring that the engine has warned up a little and is well lubricated.
My wife and I had our Opel Corsa automatic for 12years. No eating in the car, and regular maintenance.... In the 12 years of driving it, only had a problem 1 time. Doing about 70, and about 1.5 km from the toll booth. Foot off the gas, slowing....press the brake...nothing...no brakes.....never happened before. Had to use the gears to slow me down. I got it stopped, got to my turn...paid the toll....went through...and parked at the side of the road right there. Sit there, relax...inspected the car...nothing wrong. Start the engine, put it in D....rolling forward...brakes worked, no problem. Next day, took the car to the Opel mechanic....he did his thing...and found nothing. So, something to do, so you don't hurt the transmission......learn how to use gears to get you stopped if brakes fail. (Wife sold the Corsa eventually. It was immaculate, inside and out
It’s not really an issue in automatics because the shifter is attached by a cable and the selections on the shifter that will cause damage you need to apply the brake first. In manuals that’s a no it’s more dangerous in a manual to rest your hand on the shifter because that shift is a direct connection to the transmission and you can ware out the selector and the gears will start to grind everytime you shift
@@ryans413 My automatic Opel Mokka doesn't have a shift stick that is attached to a cable. It has a small electronic switch instead, so nothing there to rest your hand on..
my mother almost never completely stops her car when she shifts it from reverse to drive. I do and she thought I was weird, one time she even told me to speed up! Now I know that I am treating my car well when I make that short stop.
I drove a few standard transmission cars, and would frequently coast down hills. The newest one I owned was a 91 accord, though. Others were from the 80s. I *did* help my fuel economy a lot. Whenever I filled up, I divided the number of miles on the trip odometer by the number of gallons to fill my tank, and then divided (and reset the trip odometer).
@@dennisbonville3217 - I think for myself that I'd like to carry a little pocket knife with a locking blade so I don't accidentally cut my fingers while using the tool. Oh wait...
LOL that’s crazy idea to recommend putting car into park at stop light! If everyone did that only a fraction of the cars would make it through the light. I would also suspect people putting into gear and immediately hitting the peddle too hard.
Tip 1 is not very accurate. Let the vehicle in drive when you are park (traffic) is good as it is still cycling the oil from the torque converter (since the pump is active). In P or N you risk overheat the oil more actually.
i always shift to n when cruising to a stop. it's an old auto. it doesn't rev down when the acc pedal is depressed. but so far no problem. been 15 years now.
#5. Apply hand/parking brake, no need to put car into ‘P’ or switch off your engine. Select ‘N’ and do not sit with your foot on the brake, lots of modern cars have automatic parking brakes and you don’t need to put your car into ‘P’ or ‘N’ you can leave it in ‘D’ #4. If you were to coast down hill in natural (which is the wrong thing to do), you will not be cutting power to the engine or the oil supply to the engine or gearbox. The engine will still be running and the oil is still circulating around the engine and transmission. The oil is still being pumped round the engine as it would be when stationary and the engine running, no extra damaged caused. #2. The should still park your car with the hand/parking brake on, as it will also help stop putting strain on your transmission. The emergency brake as you call it, should not be used in an emergency, that would be dangerous. It is there to keep the car from moving.
And forget to apply the hand brake because you think you are on a level surface and you are not, and you take your food off teh brake to go forward and roll back almost hitting the car behind you, as you forgot you are in neutral, as you never go into neutral..........yep done that. I'd just put it in park. That way you don't move once you take your foot off the brake.
@@kfl611 then get into remembering to apply the handbrake, its not hard if you keep putting your car into ‘P’ which shouldn’t be used if you are stopped in traffic. It is for what it says, “PARK,” Parking.
I strongly agree with all that you said except point 4, leaving it in gear is just better always when driving downhill (unless you meant that anyway), as you are running the engine off the drive wheels rather than wasting fuel letting it idle. Also engine braking, and as he said in the video, keeping in control of your car. But seriously, why does everyone NOT use the handbrake/parking brake? It's MADE for when you are stopped for a long time. It's MADE to take pressure off every other component. The other stuff is just a backup and the handbrake/parking brake is the MAIN braking force for a parked car. After typing all of this I realised you said it is wrong to not be in gear going downhill.
It's called an EMERGENCY BRAKE for a reason, AN EMERGENCY!! Like ,you know..if your normal power brakes FAILED. THE EMERGENCY BRAKE IS A PULL CABLE SYSTEM seperate from the Hydraulic brake system.
@@richardcoram1562 it may be called an emergency brake in America, but it isn’t in the U.K. and if you have an electronic parking brake the vehicle will not let you put it on in any situation if the vehicle is moving. As a retired driving instructor, I would never recommend just yanking on the handbrake, you would do it gradually and slowly.
The last point all you needed to say is it wears out the auto gearbox clutch packs because now you’re making those do the braking instead of your wheel brakes when changing from reverse to drive. Coasting in neutral you are not cutting oil supply to an engine. Oil pressure needs vary depending on the RPM. when you coast in neutral, the engine returns to slightly above idling rpm (usually 900-1100) and so the engine will lubricate itself for the need of that particular rpm.
Having listened to this and read the comments, I wonder what type of auto box you are thinking of. Do you mean the torque converter/hydraulic box? If so would the advice also apply to the constant variable types (CVT) and the dual clutch types (DSG)? I've no idea myself - I disliked the automatics I've driven, much prefer the manual box.
In Europe manual car sales are around half of the total sales chart. In Europe it became the norm for cars to shut off at lights while I drive. Our autos or manual gearboxes fed by a fast changing double clutch ( as F1 cars) against torque converter box which are heavy and only have limited gear rages 3-4 while in 5 to 9 speed boxes are the norm aiding fuel efficiency.
Excellent video man I always wondered how park worked 👍 #7 when towing stay in lower gears not drive, it will constantly try to change up and possibly overheat the gear box, ask me how I found that out ✌️ 😂
Piggybacking off of the above reply, don't tow a vehicle by the driven wheels. Put the non driven wheels on the ground or use a flatbed if that's not possible. Read your owner's manual.
I have an automatic Transmission in my car. On the side of the stick it has a small button to change from OVERDRIVE ON to OVERDRIVE OFF. My question is as follows: When driving around, in which position should I put this button OVERDRIVE ON to OVERDRIVE OFF ?
Unless you are towing or driving in very hilly steep terrain, you want to keep it in OVERDRIVE ON. Overdrive simply provides better fuel economy at highway speeds. At this setting, it still will not go into overdrive at lower speeds or when climbing a grade. Turning it OFF will give you more responsive and consistent engine braking and torque when towing.
Only do this in heavily loaded trucks and very steep grades. Most cars don't really need this and modern autos don't do much engine braking. That's a manual maneuver.
Bad idea as the pressure on the engine is reversed and can eventually lead to early crank bearing failure. Trucks use a Jake brake when going down hills or decelerating.
Sad thing about the first tip. It will kill your battery if you only do short trips. Most cars with all the touch screens and road cameras on the windshield still draw power from the battery even when they are off. Starting your car draws the most amperage from the battery. So please. Never turn off your running car on the road. Otherwise you might hear the 'click,click,click' and you will be stuck. I learned this the hard way and even the old "let it run for 30 minutes" is not enough for modern electronic cars. I had to call road side assistance in my driveway once because I only put 900 miles on a 2021 Toyota and the battery died. (the battery was fine, it was the constant engine stopping and starting that finally drained it.)
I disagree with #5. Leaving the transmission in D when idling for quite some time will not really damage the transmission. It will however wear down your ATF more quickly. Additionally, when you are just idling, avoid putting the transmission in Park (P). You might accidentally damage this if you do it while the car is on an incline and the pawl bears the weight of the entire car.
Drove my first brand new 2005 tacoma ALWAYS just in DRIVE and around just over 100k the transmission started to slip. My latest brand new 2015 tacoma and I say brand new because I am the only owner but anyway I NOW use 4 more around town and then put it in drive when I am about to get on the freeway to prevent the ridiculous amount of up and down shifting the tacoma transmissions do just on local driving. I will also run through from park to low 1 just going through all of the transmission options at a stop just to make sure the linkage stays thoroughly operational and allowing the transmission to be properly maintained on the inside so that no passages inside the transmission ever have a chance of clogging up if you will because the first transmission should have never started to slip after 100k, that's ridiculous. Also just letting you tacoma owners know, my 2015 tacoma transmission was way overfilled and I contacted Toyota but they don't care!!!! I also noticed a slight bit of "wetness" developing on the backside of the transmission cover telling me that was caused by too much pressure from being way overfilled!!!!! It's as if it was done on purpose to eff up my transmission on purpose WTF!!!!!!!!!! But anyway I have my transmission service down to a science leveling the truck using a level on the transmission pan and a laser thermometer when to pull the level check plug.
Shifting from reverse to drive without coming to a complete stop. I had a friend I used to car pool with who had a 90s Pontiac Grand Am and he did this ALL the time! He'd back out of the parking space at work and immediately shift into drive. Needless to say, he wound up having to buy a rebuilt transmission when his failed one day on the way home from work!
It was an old Pontiac lol like you said. It had probably nothing to do with it at all. If you don't replace oil regularly on old automatic transmission they will fail cause they literally rely on two propers in an oil pan.
In case of a emergency or no battery in some car like my Mazda CX 5 you can not move the shifter if the car is not running or have no more battery juice . so if you have to push the car you need to put the shifter in neutral . Like my cx 5 and in your CRV you can see it at 2 ,10 in your CRV . to the right of the shifter you have a little plastic panel about half of a inch. you lift this little panel and under that . you gone a have access to a pin you have to move to be able to reales the shifter freely . it happen to me in a parking airport in winter
I remember reading an operator manual (not everyone takes the time to read those, remember the folks who built your car probably know more about it than you or me). It told me to apply the parking brake before taking my foot off the driving brake (foot brake, brake pedal) and when it is certain the parking brake is holding the car then, and only then, put the car into PARK. Used to be the hand brake was actually intended to be an emergency brake but nowadays many of them are foot operated and are only for holding the car when stopped/parked. I actually regret spending time viewing your video,
Thank you for an excellent video. Especially, the Rosary and the beautiful religious icons you display in your car, love your superb expertise and enthusiasm. Keep up with the great work of instilling your automotive knowledge with others like me. Definitely, I will be mindful now when driving my automatic vehicle. May God bless you and yours!
Driving the vehicle downhill in Neutral does not do any harm to any part of engine or vehicle. It has one problem that you do not get engine braking. Otherwise your engine is disengaged from wheels and high speed of vehicle will not put any burden on the idling engine. Avoid going downhill in Neutral only because you will not get any engine braking. L, L2, L1, 2, 1 are all designed for downhill drive in automatic vehicles.
Thanks for this..very important!the illustration was on point really helped me to have a better understanding so when i begin driving i'll always have that in my head
One Toyota mechanic popular on UA-cam advises not to change to N when stopped, claiming constant shifting will cause more wear. I always used to change to N when at lights etc, now not so sure.
I live in Canada, not I'm not sure of the new transmissions, but they only pump fluid in gear and N. So when I'm waiting on that long red light or train in winter or those hot days, e brake is on and vehicle in N so that transmission is still pumping fluid.
First, there's no such thing as Torque Converter gearbox as-is as a Torque converter is simply a part of a transmission that serves as a substitute for a clutch and flywheel in a manual transmission. Both CVTs (Continuously Variable Transmission or Variator) and ATs (Automatic Transmission) utilize a Torque Converter and both considered as "Torque Converter Transmissions". On the other hand, AMT (Automated Manual Transmission) is essentially a regular Manual Transmission that gets it's clutch and the gear selector controlled by a mechanism which in turn is controlled by a computer. Whereas an IMT, just like AMT, is a Manual Transmission that has its Clutch controlled by a computerized mechanism whilst letting the driver freely select between gears. Note that AMT lets the user decide whether to use the Automated or Manual mode while iMT can only be controlled manually.
i've never driven autmatic cars since i've never seen the appeal of one, but this video has been very useful if i ever find myself driving one, thanks!
I'd probably settle for just using Park at a stop light or crossing. After all if you're turning the car off and on constantly, doesn't it stand to reason that it'll wear out your starter motor a lot faster?
@ 1:39 Stop at traffic light! Press the paddle brake and shift to N, continue pressing on the brake until you are ready to shift back to D and drive on as your foot will have to release the brake paddle and move to the accelerator paddle. Take note that you are also giving a signal to the car behind you that you are ready or not ready to drive on. Doing this will help when it rains or snowing when visibility is poor! I don’t encourage switching off/on unless the car stop/start automatically as in later models. Reason being it will drain out battery power drastically to crank the engine. Newer model car uses high capacity AMG battery designed to accommodate electronic features in the car.
Always leave your car running it in gear so if you left to move your car regardless of what's around your car because the train is derailing don't listen to this man always stay safe keep your car in gear and be ready to move at any time for any reason always have your safety over everybody else's
There are a few things garbled or mixed up in this video. As to the engine getting starved for oil if you shift the transmission to neutral when going downhill: the engine oil pump is not at all affected by vehicle speed, only by rpm. The engine's lubrication needs, as well as its lubrication delivery, are solely determined by rpm, although there are other reasons why it's not a good idea to shift to neutral while going downhill, as you pointed out. But the biggest goof is your explanation of what happens in an automatic transmission when you shift from a forward gear to a reverse gear or back again. I would suggest that you watch some videos on how a planetary gearset works (the heart of the automatic transmission). It is an amazing system! The gears are always in mesh and they always turn in the same direction - they never reverse! The amazing planetary gearset can provide various gear reductions, overdrive, direct drive, and reverse, all by simply locking different members to the case (or each other). In other words, by driving one member while taking power output from a different member. With a sun gear, ring gear, and planet gear carrier, this is all possible through the use of clutches or bands, which lock members together or to the transmission case (stationary). The clutches or bands are the components that might be damaged by rough shifting, although most transmissions for the last 50 years or so would not permit this. I enjoyed your video, though! (I used to teach this stuff!)
Yes, you can if you're talking about engaging the "Sport Mode" button. Sport resets the transmission computer to downshift more responsively. Better throttle performance with negligible extra fuel consumption.
I always put the car into "P" when stationary at a red light, a train crossing, or a non-moving traffic jam. It also removes the risk of the fuel pedal getting accidentally hit. I also pull the handbrake on first before putting it into "P". The worst thing you can do to an auto box is to rev up the moment to say 5000 rmp and then drop it into gear in order to smoke the tyres.
Old hot rods used to do this by dropping the gear into spin and putting it into gear, grinding the clutches. Most times the gears were strong enough to handle this torment but these days, car gears are small and not strong enough to employ this tactic. These days, you have to install a Dinan Chip with modified air intake and larger exhausts to make it run faster. Having modified engines allow the car to breathe more efficiently and run higher RPM using synthetic oil from Mobil or Castrol Synthetic. Or better just order a Tesla with “Ludicrous “ mode and watch it go 0-60 in three seconds like a $2 million Porsche Twin Turbo Whale tail, or the lesser priced Nissan GT-R twin turbos, or the 1987 GM Grand National GNX.
UK Most cars are stick, coasting out of gear is illegal in the UK. Emergency brake? It will not stop the car because it bypasses the hydraulic master cylinder. UK known as Hand parking brake, manual box leave in gear for safety. Symple
I was interested to see what you had to say so I watched. To me these are all common sense. Shouldn't even have to think about not doing them. If you really value your car and especially the transmission you would not do these kinds of things. I never have. No one had to tell me to not do these things. Don't know why I automatically knew not to do them. Like I said. Just common sense.
It’s because you can feel the shifting after a while and easily recognize what is and isn’t healthy for your car, but not everyone is as intuitive and that’s fine. We all have our strengths and our weaknesses. Common sense to you might not be to someone else with totally different life experiences.
A cop in Youngstown AZ was chasing a another car that had just robbed a business and was fleeing. The road he was had an S turn that could only be driven through at low speed. The robber made it through, but the young officer forgot where he was and when he got to the turn he tried braking but it wasn’t enough, so he shifted through revers into park. The transmission exploded, leaving a huge hole in the transmission tunnel. The cop was lucky he was uninsured. He could have lost his leg doing something so stupid. This is why drag racers use transmission blankets, to keep fragments from a blown transmission out of the car.
my c5 Citroen requires me to put the brake pedal for changing gears (shifting). That's Quite clever. Because pressing the brake pedal firmly requires the car to stop and this ensures that the gear does not change while moving. . Of course, you can put the lever to the left in manual mode and control the movement with heavy or light gear. i like it😑 They have thought of everything.
@@wilwert1746 that's not my design but why this future should makes driver dumb? Anyway it needs a mechanism for moving lever from p position,so why not instead of pushing button on side of lever changer,with hand,push stop pedal and hit two targets with one bullet?!
The gears between forward (drive) and reverse are totally separate sets of planetary gears that are in constant mesh (never disengage) the band for drive tightens by a servo locking the outer drum of the planetary gears, the same in reverse, the drive band is loose & the servo on the reverse set of planetary gears tightens ! What happens if you do it while the car is moving is excess stress is put on bearings, bands, U-joints and other parts. Model T Fords have planetary gears controlled by foot pedals rather than servos controlled by oil pressure or electronics in newer cars. Google "planetary gears" and auto transmission servos for more info.
At the traffic light stop, isn't it better to shift the gear to Neutral and pull up the hand brake rather than shutting down the engine or shifting to park ? The owner's manual of my car clearly states:"Parking for a short time, shift gear to Neutral (N) and pull up hand brake. Do not press and hold the brake pedal in (D) or (R) even if you park for a short time as this will impair the service life of automatic transmission"
Engine Lubrication is separate from transmission. In neutral downhill there is plenty of airflow to keep engine from overheating. HEMI's lack sufficient oil pressure at idle causing excessive cam wear and eventual misfire. Wonder how often the starter needs changing on the vehicles that shut down when idling?
When you have the pan cleaned, make sure they brush out the metal shavings and use a magnet, Jiffy Lube did not do this and it ruined the transmission. Expensive lesson!
Never park on an incline with weight of vehicle resting on park mode internal holding gear piece (which can eventually break that important part in the transmission). Engage parking brake first, put car in neutral & let weight of vehicle first rest on engaged parking brake, & then finally put transmission in park mode & turn it off.
I think this was a good video - so thanks. That said, I take exception to your statement that rolling downhill in N can overheat your engine. Simply false. I’m not saying your other reasons for not doing it aren’t valid, but if the engine is idling, the amount of oil being distributed through the engine is just fine. Engine heat comes from the friction of the pistons and other moving parts. When in N the engine is disengaged from the rest of the drivetrain - no addition heat is being generated than would be if it were idling at a stop. If anything, the engine will run cooler that it would at a stop due to the increased airflow.
Thought I would learn something new, aw well. Guess some people take the time to learn how a tool works, and some just stick to the basics. Must be the reason for all the new sensors and gadgets on new cars. At the same time, you never stop learning. Bought a Subaru with all the gadgets, it’s nice but had to learn about the new gadgets. Parking in a hill using electronic brake before putting the car in park. You can feel the brakes engaging and taking pressure off transmission. No matter what, I still turn my wheels into the curb.
Sitting in park is harder on the transmition than drive. Any time the engine is running, the engine flywheel turns the torque converter body that drives the transmition fluid pump. This is a direct drive link no matter gear selected. When you idle in park the drive train holds the transmition input shaft so no other parts of the transmition are moving. The torque converter fins free wheel with no touching parts to wear or generate heat. In neutral or park the bans engage, gears spin, but the output gear disengages. This generates friction and heat. The fluid is air cooled so if you are not moving or fans running you are not cooling. sitting in park will increase wear and heat.
Hey, you live in Akron, when you were talking about don't coast down a hill. That road is portage path going into the valley. Stand Hewett is in the other direction. Cool, I notice that as you started down portage path's hill. Great job.
Makes perfect sense. I was driving my automatic like a manual and ruined it. Coasting in neutral, braking in drive and shifting into park to stop. It was "automatic" it wouldnt let you do something that you shouldnt, would it?
What about the Sport feature on some automatic cars? My edge has it, but I don’t use it
The sport feature with the +/- allows you to shift your gears rather than the computer. It's a super great feature because it gives the driver more control but can potentially damage interal components if not used safetly. The biggest takeaway is not to hit "Red Line" which is the red portion of your RPM's when using sport mode! Love to see more cars aquire that fun feauture
@@rammiq that's the manual feature, not the sport feature. the sport feature optimizes the shift points where the drive position tries to save gas at the expense of performance.
The sport function lets the car accelerate for longer before changing up a gear. This uses more gas but is fun!
It's better for your clutch to drive in sport, especially when slowing down or before coming to a stop shift into sport.
My 2017 Mazda CX-5 has a feature that allows you to manually upshift or downshift, without the need to manually depress a clutch pedal.
#6. When parking on a hill...first shift to neutral, then set parking brake, then shift to park. Now the weight of the car is supported by the brake not the transmission.
But when you're driving the gearbox takes all the torque from the engine so i would think that it can hold the weight of the car on a hill!
@@janmolendijk8110 bro , you’re wrong.The part (parking pawl) holding the your car is not very strong , it might break.
Fucking awesome tip bro! Definitely going to start practicing this regularly. Thanks homie! 🤟🏽
Why neutral?..I think its ok to brake wth the foot paddle then hand brake then shift to park
Shifting to neutral and the particular order does nothing here. The takeaway is to just both use the parking brake and shift to park whenever you park, on all types of surfaces and inclines.
Manual transmissions have become a secure way to prevent theft since no one seems to know how to drive one anymore.
LMAOOOOO
Where do you live? America?
you can still push the car that’s if you don’t have it secured
every experienced thief will already learn to drive anything.
@@gregory3434There's a parking brake for a reason.
#6: Get into the habit of using the parking break. You want to place the brake and then release the footpedal. That way the weight of the car is on the parking break and not on the transmission. This is very important on a hill, the car can jump out of the park position if you only use the transmission (learned from personal experience, family member was almost killed).
Did you forget to press and hold foot brake when starting the car ?
The transmission is made to hold the car still. It will not damage the transmission. It is made to lock the transmission depite the angle of the car. Emergency brakes vary and depending on the hill, if that's all you use, you may find your car at the bottom of the hill. A properly working transmission will noy "jump" out of park. You can tow an 18 wheeler using a large enough chain and the parking paw from almost any auto-trans.
brake ,not break
@@jonblachley1911 The parking setting on the automatic transmission is often just a pin, its not designed to hold the car at an angle and it can jump out. Its also bad for the transmission to hold the weight of the car against that pin. By adding the emergency brake its an additional level of security (you still have the car in park after all, its not as if you can leave it in neutral) and its one that is better designed to hold the entire weight and not simply jump out. If you emergency break doesn't work, you need to get it checked. Perhaps big trucks have a more reliable design since they have to carry large loads, but you can't extend that to all cars.
I can tell you from personal experience, I have seen a car jump out of park and it almost killed my brother. If he had set the brake, it would have been an additional layer of protection and would have saved him.
Fords, Audi’s, and some Nissans has issues with parked cars. They tended to roll out of normal park position and end up down a hill at full speed.
The newer cars all have issues with “Sudden Acceleration“ and two of them are notorious, they are the following:
1)1985-2011- Audi’s all types.
2) 2000- present -Tesla’s due to Software Computer glitches. Most incidents still under investigation by the NHTSB, the DOT, AAA, IHSB, UK , CDOT
The BEV are the most dangerous, they accelerate suddenly, hit a concrete pillar or highway speed obstacle and sometimes trap occupants and explode like a phosphorus grenade, water will not put it out, they have to use a chemical sludge gel that comes from certain marine animals, or they just bury it in sand to smother the fire but it still burns for a couple of days sometimes. Not do good for trapped humans or pet animals!
you forgot one very important thing and a lot of people ignore this; when your car is parked on a slop or hill it is imperative that you put the car on neutral and then put your leg/hand-brake, release foot from brake so that the cars weight will fall on that instead of the gearbox, once that's done then you can shift it from neutral to park. When this isn't done and it is put directly to park, when you are either reversing or driving forward, you'll feel a huge resistance or vibration /hear a thump in your gearbox. Anyone notice this?
I usually engage neutral, then handbrake, release foot from brake to ensure the car wont move, then engage Park. This way, it won't damage the gearbox
And if you can remember it, turn your wheels inward or outward, depending on if you are facing up hill or down hill, in case something does go wrong or you car is hit by another car so the little bit your car may move, the wheels will hit the curb and hopefully keep it from moving too much.
Spoken like a person who has paid to have the parking pawl replaced.
Thanks for that bro ....

Beautiful rosaries and icons, wonderful little details in the video. God bless you!
BAD IDEA! Anything hanging from the mirror is illegal. This includes air fresheners, your baby's first shoes & other such items. You probably wouldn't get stopped for things hanging there, but in case of accident, it will be your fault & you could get ticket. The violation is OBSTRUCTED o r DISTRACTED VISION..
Don't forget if you're going down hill, and the roads are bad, you can shift to D1 or L to put it in a lower gear. This will prevent the car from speeding up too much, helping you keep better control of the car.
Correct. 👍
I shift to a lower gear range going down a long hill regardless of road conditions. I've heard from reliable sources that the rule is ' if you have to brake more than 25% of the length of the hill, change to the next lower range'. I'm often behind vehicles riding the brake down the entire length of an 8% hill that is 3/4 to a mile in length, this practice produces incredibly high heat in the braking components (my truck has 97,000 miles on the clock and still running original brake pads).
You can also down shift to have better power up hill, since we are talking beginner tips.
One can shift down too just before entering a sharper corner!
👍
It was so nice to see the rosary hanged in the mirror.
Thanks for the tips.
All the points made in this video are important. I would add a 6th. "Never allow transmission fluid to get worn down and degraded." The worn down and degraded transmission fluid will not properly protect the gears and other in the transmission. It's best to maintain the transmission at the recommended maintenance schedule of the manufacture. Few do this and the result is a worn down and degrated transmission fluid that is not able to continue to property protect the moving parts of the transmission.
Good advice. The enemy of trans fluid is heat and time.
I drove large cars for 40 years. Most had manual 10 or 13 speed Road ranger transmissions. However, in my personal vehicles, I preferred automatic transmissions.( 'cuz I ain't working when I ain't) Of all my automatics, I had one torque converter fail.
Most are untrue
Exactly regular changes and after any overheating incident. Remember 99+% of autos use radiator based coolers( dumb design). Even though the trans temp range is well above coolant range it's always better to cool in ambient Temps than at 200 degrees.
Park or neutral is better than turning the car off. You want the engine running to continue to pump the fluid and cool the trans while its sitting. Otherwise you're just letting it heat soak.
And when you reach your destination how long do you suggest that drivers keep their engine running for ?
@@harrygatto depends on the car and how you were just driving it. Hard highway running a couple minutes. Town driving maybe one minute. Turbo car a couple minutes to let the oil drain out of the turbo.
@@shadow105720 Turbos are off-topic as we're talking about automatic transmissions. In addition, you're wrong about why a turbo engine should be allowed to idle before switching off; it's to allow the bearings to cool while the oil is flowing and stop the oil from being burned into the bearings. Unless you want to explain how keeping the engine running allows the oil to drain from the turbo?
You have no idea what heat soak means. If what you said is correct then everybody heat soaks their engines.
Heat soaking is when the engine temp doesn't drop after shutting the engine off. It either stays the same or goes up.
About #5, only put the vehicle in park if you are turning the engine off and setting your brakes. If you keep your engine running at a traffic stoplight or train crossing, best to just shift to N. There are incidences of distracted drivers who are at a full stop, engine running and set to park where they have their foot on the gas pedal unawares. Once they try to shift to drive, the high rpm from foot on the gas pedal causes engagement when it passes the R position, causing the car to reverse quickly, and as the sudden backward jerking motion of the car causes the driver's body to pitch forward in the seat, the gas pedal gets depressed more as the hand on the shifter is moving into D, which causes the vehicle to lurch forward and the driver to lose control due to disorientation.
I drive manual but learned on an automatic transmission, and I was told that also going in neutral protects your transmission and engine if you get hit from behind. If you put in park instead, you will definitely get damage to the transmission in addition to all the other damage.
You can't put the car in gear without your foot on the brake. if it is on the brake, it isn't on the gas. unless you're a race car driver.
Not for Nissan CVT (I had 2 Nissans, unknown other brands/CVT), Nissan CVT, N might be only good during towing, turnoff engine or P is okay (no N during temporary stop).
#1 When I am stopped at lights, I usually move the gear shift to Neutral and apply the handbrake. #4 In many states, coasting in Neutral is illegal.
How would you get caught lol
@@jrob5115 You can get busted by the Coast Guard
@@andyb7855 gold
Thx a lot, i used to shift into drive without being completely stopped, I won’t do it anymore.
But at one part you said it’s OK to rest your hand on the shift knob, on manual cars you’re not supposed to do that.
Keeping your car in drive at a stoplight is a good thing if you need to move quickly to avoid an accident.
And this is why we have transmission coolers built in to the radiator and this is always why there’s a torque converter you shouldn’t have to worry about heat. I will agree stopped at a train put it in park I do this because my foot gets tired holding the brake.
But my car owner's manual strictly advise against this "Parking for a short time, place the gear lever at neutral gear (N) and pull up the hand brake. Do not press and hold the brake pedal in (D) or (R) even if you park your car for short time as this will impair the service life of automatic transmission"
@@steventan2550 yea but the engine at idle is a very small load on the transmission it’s worse to be on a hill with your foot on the brake because that’s putting a load on the transmission but it’s very little.
If your car over heats,,,, get a better car.
Also another reason not to use neutral when going downhill is that when gears are engaged, the engine will partially slow down the car (engine braking) and that will spare the brakes slightly. In fact if u manually shift to a lower gear (downshift), u will increase engine braking which will reduce the chance of brake fading or brakes failure and will increase the longevity of ur brakes when going downhill. But if u do that avoid shifting into 1st gear as that will significantly slow down the car and could even damage the transmission and engine. Also watch the RPM counts when doing this manually.
I would never put my car into park whilst simply waiting at traffic lights as going from drive into park and back again can cause unnecessary wear on the engine. Also, the driver behind you is more likely to think what is going on when he suddenly sees reversing lights on the car in front, however briefly that may be.
Absolutely no increase in engine wear doing this but I agree with avoiding placing in park. Neutral is fine and apply handbrake while at lights etc.
I agree, when the intention is to keep engine on.
If the intention is to turn of the engine to save fuel,
transmission in park is a layer for safety.
The wear is not only on transmission, also in air conditioning + sound system + air purifier + whatever on,
because it all need to be turn off.
So when the engine is turn on again, electric doesn't get burden.
I’ve sometimes changed from Reverse to Drive before it’s completely stopped. Thank you for the advice!! Glad I watched this video!
So it’s not the best you have to come to a stop n change or??
I've been guilty of that too. 🙁
Or do what most of the world does and use a manual gearbox. It gives you better control and prevents most of the problems here.
Number 5 is wrong, the slip occurs in the torque converter not the clutch on an automatic. Your transmission won't overheat from shaft speed mismatch in the converter, but your engine will be marginally happier so it is still a good idea
Number 4 is wrong, unless your oil pressure gage reads low pressure you have proper oil circulation, hot oil runs like tap water. Don't put it in neutral going downhill anyway though because it is stupid (main reason not to do it) and actually wastes gas (in fuel injected engines). When rolling, the power input to the crankshaft rpm is wheel speed and your ecu will deliver less fuel, whereas in neutral, crankshaft rpm is determined by fuel air ratio (injection volume, or throttle clearance for carburetors) so your ecu will deliver fuel to achieve idle rpm to keep the alternator above 12.5VDC. If the driveshaft can turn the crankshaft fast enough to spin the alternator to 12.5VDC output without fuel delivery (typically 7.5 mph vehicle speed if in first gear) the ecu will deliver the minimum fuel to keep the engine running which is actually less than idle fuel injection volume. The difference in volumetric fuel delivery is about the same as the difference between a cold choked carburetor and a hot carburetor, but if you're shifting to neutral to save $0.12 on gas you might as well do it right
All in all, good list, the reasons are just a little off
Then why does the computer indicate that the instantaneous MPG goes much higher in neutral going down hill?
@@randalrhoades8482 because the engine is running unloaded. Rolling down a hill in gear requires no fuel to spin the engine, the driveshaft is spinning it
Fuel injected engines automatically shut off the fuel when the throttle pedal is released when moving.
@@randalrhoades8482
@@randalrhoades8482 If you have a mpg screen, lift your foot off the gas. It should read 99.9mpg.
I used to have a Fiat Argenta automatique with a 2l twincam engine, my favorite trick was to rev the engine to 5000 rpm then put the gear select in drive 1, the back wheel used to spin on the road like a clutch until it got grip and the car shot off like rocket. It lasted for years and years.

You should always use your handbrake when you are parked, it's not an emergency brake !! If you don't use it on a regular basis it can seize up and won't be there when you need it !!
This is a really good point.
#1 depends on the circumstance. The engine will be fine if it’s still in drive since the clutch is in, meaning that the transmission is disconnected. It is basically like having the clutch in on a normal manual. I would only really do it for example at roadworks where you’re stopped for 10 20 minutes. What isn’t good is leaving the car in drive in any case or in park without the handbrake, which could cause major damage to the gearbox.
My idea for extending the life of an auto transmission is, as you accelerate from standing, and the transmission is shifting up through its range with increasing road speed, briefly lift your foot pressure from the accelerator just as the trans shifts to the next higher gear; similar to what you do when shifting a manual. This takes the load off the clutch bands momentarily as they are loosening and re-tightening, reducing wear on the bands.
I’ve always done this naturally but was never 100% if it was actually helping out anything lol
That has many benefits, mileage, wear and tear etc. This habit is most often found in drivers who learned on manuals.
By the time you felt that shift it was to late to have done any good.
@@horsepowerandtalk1033 The trick is to know when the shift is about to occur and anticipate the letting up on the accelerator. My Ford Escort has over 300,000 miles on the original tranny and it still runs quiet and shifts smooth.
@@antoniograncino3506idk about the escort but some other ford V8 models like the crown Vic already have that feature inbuilt to the transmission computer. Each time the tranny shifts the engine power is reduced for a second by reducing spark advance. So the car will do it anyway.
Last thing I never thought about, good to pause a second before going to reverse !!, thanks
Thanks. Most of these things are common (technical) sense. But I found it useful to know why not to keep the car running in D when standing a long time. (Most modern cars now have a start/stop automatic.) Question: Why not put into N instead of P while standing e.g. to keep the heating on during winter or the aircon during summer.
I wouldn't want to coast downhill in N anyway, as it is much less secure. Now I know there are also technical reasons not to.
With modern e-cars and hybrids I would like to add, that often D is better than B. It might depend a little on your driving style, but generally speaking sailing saves more energy than breaking returns to you. Downhill it is another story where you can use gravity to charge your battery.
Neutral is fine at a standstill like a drive through, but I'd put it in park if it's for a longer period of time.
All good information for a lot of people son. I'M NOW INTO MY 55lth year of driving vehicles with automatic transmissions. I've never had a any of my transmissions to break, fold or mutilate ever. I do a every 3 to 5 year full service on my transmissions, otherwise I drive them similar to how I would drive a standard. I use my gears a lot. Current vehicle, has the TH 700 and I will shift to low ,like as I'm turning to run down the on ramp to the interstate or expressway. I run up to 45 at times "getting into it" to be up to speed limit when entering freeways I'm now in 2nd gear as I enter the freeway, then I cool it at 70 mph and shift into drive, then Overdrive..I also run through all my gears occasionally, pushing the tachometer up close to redline..1st 45, 2nd 95, 3rd135, and 4th 150+. and this car and transmission are all original, with 2002000 k miles. My work trucks all had me driving 10, or 13 speed transmissions, and why I never wanted a stick in my car. My first cars were all stick shifts, but once I started trucking. I preferred my automatics. ❤
I think the transmission gain (based on my limited knowledge of them) has drastically improved performance in the 90's changed the automatic side of things for the better.
Good video. I always put my car in neutral at every red light, always have.
Sadly even here in the UK we are losing the battle against the automatic gearbox, almost 70% of all new cars sold in 2021 were automatic Vs 15 years ago 80% sold were manual transmission, I have a manual car, but regularly drive a friend's sons automatic car and yes easier less to do but nowhere near as smooth and responsive as a manual car
this is so wrong. An automatic car, especially newer automatics are much better than any manual driver. During the 80s and 90s when cars were becoming automatic, sure a good manual driver was better than an automatic but nowadays there is no comparison. Its a better shifter than you, its better at fuel economy than you, and yes its smoother than you. Smoothness is definitely a thing when it comes to CVT. Hell some CVTs fake a motion for gear shifting since people don't like not having that.
Unless this car is old, your friend's car is better than you. What you don't like is the difference and thats perfectly fine. You are just under a placebo effect. You are used to how you drive and how your car handles. And you don't like the difference in feeling. And since you don't like it you convincedd yourself its bad and thus its bad.
I have a Skoda Karoq 1.6 tdi. (VW technology). DSG automatic. Seven gears, smoother and quicker gear changes than any manual driver. Driving for economy and not exceeding 60mph, up to 64 mpg. That’s UK Gallons of eight pints, US gallons of seven pints=56 mpg.
Sadly the same thing is happening here in Australia. My mum wanted her new Honda Civic in manual and was told that they don't make them anymore and she had to settle for the cvt transmission. Over the years I have driven lots of things from road train trucks with 15 speed non-syncro manual boxes to the basic hilux manual boxes. Automatic gear boxes were a luxury back then. I still drive lots of manual things for work but my personnel driving car is an auto, it's a V8 and should, by rights be paired with a manual. I bought it second hand and didn't really get of a choice. As they say now a manual transmission is the new theft deterrent.
@@densetsu4286 you opened that poor man up and read him like a book. 😂
@@densetsu4286 not the case my friend's car is a 2020 VW and has a DSG gearbox and has awful gear change in the lower gears especially pulling away from standstill, and I don't know how you can tell me I am wrong have you driven this individual vehicle, NO you haven't, I like the idea of not having to change gears, I have never driven a CVT but have driven manuals, the old school and DSG autos and up till now I still prefer a manual as I still find them smoother to drive, and untill I drive something that changes my mind i will retain my opinion
Coasting downhill in neutral isn't wise, but it won't damage either the engine or the transmission.
It doesn't matter if the car's going 35mph and the engine's idling, the engine-driven oil pump will provide lubrication to the idling engine.
In a true fluid automatic the torque converter is basically a big oil pump which drives the transmission. If the engine is idling it's still spinning the converter, which in turn is pushing fluid around the transmission.
The advice is the same in a manual, not to coast in neutral, but with either type of transmission the only reason is for safety, in maintaing full control of the vehicle.
Ya fer sure. Engine oil pressure has nothing to with in gear on not in gear. Oil pressure increases when revs increase weather theres a load on the motor or not.
An idle engine might provide enough lubrication on perfectly level ground sitting still but going 45 around a corner probably not. Some cars stock oil system cant even cope with that normally for long periods of time. They're made to a bare minimum.
Most important ! Put your car in neutral at EVERY stoplight
Although I've never done it myself, I agree with the the warning not to put the selector in Park or Reverse until the car comes to a *complete* stop!
The last one is not 100% true on all trans some have if I’m correct all have a separate reverse gear that has different gear threading made to go the opposite way and all the other gears are disengaged when reverse is activated
also this tip does not 100% apply to oil transmission types. (I don't know its English name, but in it, there is one gear that spins oil and another gear that gets its spin from the oil.) Some car manuals even tell you to shift from drive to reverse without breaking if you get stuck in mud or snow. But I still would recommend following this tip, coz it really does wear your transmission, even if it was designed to withstand it.
@@esa689 true personally I will go from reverse to drive but I let the car naturally slow down reversing while I’m still breaking before I hit the gas to go forward even tho it’s in drive because that’s where it would cause damage and wear
As a ASE MASTER TECH
The part of shifting to neutral at a long stop was maybe a good idea but since the modern electric shift /pcm controlled a pintel reduces / loses pressure to the 1st gear clutches doing this for you it instantly closes on throttle movement & brake release ,possible a few truck models don't though
You need to use manuf. ATF Fluid only
as they all use a different friction modifiers
That can cause the disks to wear & grab , or slip heat up more without
When I was learning to drive (UK 1970's) my instructor had a student who accidentally put the car in reverse at around 35 mph. result: 1 trashed transmission.
that car was a piece of crap. we used to do neutral drops and roll backs in our old gm cars. they just kept on going.
At 16 I thought it would be a good idea to shift into low to go up a hill. Owner of car sitting next to me and my Dad in shotgun seat, all three front seat. 1958 Buick. When I pulled the shift lever down to where I thought low would be the rear tires locked up, going about 25 mph. Dad started hollering, George did not say anything. I calmly put shifter back to drive and continued on with Dad asking me what I was doing!? Anyway, taught me a lot of lessons. The car was just fine, good old American Iron.
Thank you for the lesson!
I learnt not to change the gear abraptly cause it might damage the gears esp from drive to reverse... I guess I do that a lot...
Resting your hand on the gear stick is a very bad habit and you should get out of that.
Another good practise habit to get into is to let the engine achieve normal idle speed before putting it into gear and driving away. This allows the oil to circulate completely ensuring that the engine has warned up a little and is well lubricated.
My wife and I had our Opel Corsa automatic for 12years.
No eating in the car, and regular maintenance....
In the 12 years of driving it, only had a problem 1 time. Doing about 70, and about 1.5 km from the toll booth.
Foot off the gas, slowing....press the brake...nothing...no brakes.....never happened before.
Had to use the gears to slow me down. I got it stopped, got to my turn...paid the toll....went through...and parked at the side of the road right there.
Sit there, relax...inspected the car...nothing wrong. Start the engine, put it in D....rolling forward...brakes worked, no problem.
Next day, took the car to the Opel mechanic....he did his thing...and found nothing.
So, something to do, so you don't hurt the transmission......learn how to use gears to get you stopped if brakes fail.
(Wife sold the Corsa eventually. It was immaculate, inside and out
Number 3, just avoid resting your arm on the shifter, no stress
It’s not really an issue in automatics because the shifter is attached by a cable and the selections on the shifter that will cause damage you need to apply the brake first. In manuals that’s a no it’s more dangerous in a manual to rest your hand on the shifter because that shift is a direct connection to the transmission and you can ware out the selector and the gears will start to grind everytime you shift
@@ryans413 My automatic Opel Mokka doesn't have a shift stick that is attached to a cable. It has a small electronic switch instead, so nothing there to rest your hand on..
Yes, one hand steering is lazy driving anyway. Test fail here in the UK I'd imagine.
my mother almost never completely stops her car when she shifts it from reverse to drive. I do and she thought I was weird, one time she even told me to speed up! Now I know that I am treating my car well when I make that short stop.
I drove a few standard transmission cars, and would frequently coast down hills. The newest one I owned was a 91 accord, though. Others were from the 80s. I *did* help my fuel economy a lot. Whenever I filled up, I divided the number of miles on the trip odometer by the number of gallons to fill my tank, and then divided (and reset the trip odometer).

I've learnt to stop a minute before changing gears to reversing or moving forward. Thanks
that complete stop is a major key.
100% is a major key! Keep the Lexus going for years to come!
I heard that car will ignore such changes till the full stop itself. Swich from Drive to Reverse will work the same way as to Neutral, won't it?
LOL that’s crazy idea to recommend putting car into park at stop light! If everyone did that only a fraction of the cars would make it through the light. I would also suspect people putting into gear and immediately hitting the peddle too hard.
They teach another of stupid stuff nowadays. I've been a mechanic for more than 40 years and have seen stupidity grow with every new safety feature
Tip 1 is not very accurate.
Let the vehicle in drive when you are park (traffic) is good as it is still cycling the oil from the torque converter (since the pump is active). In P or N you risk overheat the oil more actually.
i always shift to n when cruising to a stop. it's an old auto. it doesn't rev down when the acc pedal is depressed. but so far no problem. been 15 years now.
#5. Apply hand/parking brake, no need to put car into ‘P’ or switch off your engine. Select ‘N’ and do not sit with your foot on the brake, lots of modern cars have automatic parking brakes and you don’t need to put your car into ‘P’ or ‘N’ you can leave it in ‘D’
#4. If you were to coast down hill in natural (which is the wrong thing to do), you will not be cutting power to the engine or the oil supply to the engine or gearbox. The engine will still be running and the oil is still circulating around the engine and transmission. The oil is still being pumped round the engine as it would be when stationary and the engine running, no extra damaged caused.
#2. The should still park your car with the hand/parking brake on, as it will also help stop putting strain on your transmission. The emergency brake as you call it, should not be used in an emergency, that would be dangerous. It is there to keep the car from moving.
And forget to apply the hand brake because you think you are on a level surface and you are not, and you take your food off teh brake to go forward and roll back almost hitting the car behind you, as you forgot you are in neutral, as you never go into neutral..........yep done that. I'd just put it in park. That way you don't move once you take your foot off the brake.
@@kfl611 then get into remembering to apply the handbrake, its not hard if you keep putting your car into ‘P’ which shouldn’t be used if you are stopped in traffic. It is for what it says, “PARK,” Parking.
I strongly agree with all that you said except point 4, leaving it in gear is just better always when driving downhill (unless you meant that anyway), as you are running the engine off the drive wheels rather than wasting fuel letting it idle. Also engine braking, and as he said in the video, keeping in control of your car.
But seriously, why does everyone NOT use the handbrake/parking brake? It's MADE for when you are stopped for a long time. It's MADE to take pressure off every other component. The other stuff is just a backup and the handbrake/parking brake is the MAIN braking force for a parked car.
After typing all of this I realised you said it is wrong to not be in gear going downhill.
It's called an EMERGENCY BRAKE for a reason, AN EMERGENCY!! Like ,you know..if your normal power brakes FAILED. THE EMERGENCY BRAKE IS A PULL CABLE SYSTEM seperate from the Hydraulic brake system.
@@richardcoram1562 it may be called an emergency brake in America, but it isn’t in the U.K. and if you have an electronic parking brake the vehicle will not let you put it on in any situation if the vehicle is moving. As a retired driving instructor, I would never recommend just yanking on the handbrake, you would do it gradually and slowly.
Also give the transmission time to go in gear after you shift otherwise engine speed can catch and jerk the drive train
Full stop some don’t understand this they will shift when the cars still rolling a bit ugh makes me cringe
The last point all you needed to say is it wears out the auto gearbox clutch packs because now you’re making those do the braking instead of your wheel brakes when changing from reverse to drive. Coasting in neutral you are not cutting oil supply to an engine. Oil pressure needs vary depending on the RPM. when you coast in neutral, the engine returns to slightly above idling rpm (usually 900-1100) and so the engine will lubricate itself for the need of that particular rpm.
Having listened to this and read the comments, I wonder what type of auto box you are thinking of. Do you mean the torque converter/hydraulic box? If so would the advice also apply to the constant variable types (CVT) and the dual clutch types (DSG)? I've no idea myself - I disliked the automatics I've driven, much prefer the manual box.
In Europe manual car sales are around half of the total sales chart. In Europe it became the norm for cars to shut off at lights while I drive. Our autos or manual gearboxes fed by a fast changing double clutch ( as F1 cars) against torque converter box which are heavy and only have limited gear rages 3-4 while in 5 to 9 speed boxes are the norm aiding fuel efficiency.
Excellent video man I always wondered how park worked 👍 #7 when towing stay in lower gears not drive, it will constantly try to change up and possibly overheat the gear box, ask me how I found that out ✌️ 😂
That's what the "Tow Mode" on some vehicles does. Cuts down on the amount of gears to eliminate the hunting and creation of heat.
Piggybacking off of the above reply, don't tow a vehicle by the driven wheels. Put the non driven wheels on the ground or use a flatbed if that's not possible. Read your owner's manual.
I have an automatic Transmission in my car. On the side of the stick it has a small button to change from OVERDRIVE ON to OVERDRIVE OFF.
My question is as follows: When driving around, in which position should I put this button OVERDRIVE ON to OVERDRIVE OFF ?
Unless you are towing or driving in very hilly steep terrain, you want to keep it in OVERDRIVE ON. Overdrive simply provides better fuel economy at highway speeds. At this setting, it still will not go into overdrive at lower speeds or when climbing a grade. Turning it OFF will give you more responsive and consistent engine braking and torque when towing.
What’s your take on downshifting temporarily when going down a steep hill & using engine braking to reduce foot braking?
Only do this in heavily loaded trucks and very steep grades. Most cars don't really need this and modern autos don't do much engine braking. That's a manual maneuver.
Bad idea as the pressure on the engine is reversed and can eventually lead to early crank bearing failure. Trucks use a Jake brake when going down hills or decelerating.
Sad thing about the first tip. It will kill your battery if you only do short trips. Most cars with all the touch screens and road cameras on the windshield still draw power from the battery even when they are off. Starting your car draws the most amperage from the battery. So please. Never turn off your running car on the road. Otherwise you might hear the 'click,click,click' and you will be stuck. I learned this the hard way and even the old "let it run for 30 minutes" is not enough for modern electronic cars. I had to call road side assistance in my driveway once because I only put 900 miles on a 2021 Toyota and the battery died. (the battery was fine, it was the constant engine stopping and starting that finally drained it.)
I disagree with #5. Leaving the transmission in D when idling for quite some time will not really damage the transmission. It will however wear down your ATF more quickly.
Additionally, when you are just idling, avoid putting the transmission in Park (P). You might accidentally damage this if you do it while the car is on an incline and the pawl bears the weight of the entire car.
Suggest you all just learn to drive...

Drove my first brand new 2005 tacoma ALWAYS just in DRIVE and around just over 100k the transmission started to slip. My latest brand new 2015 tacoma and I say brand new because I am the only owner but anyway I NOW use 4 more around town and then put it in drive when I am about to get on the freeway to prevent the ridiculous amount of up and down shifting the tacoma transmissions do just on local driving. I will also run through from park to low 1 just going through all of the transmission options at a stop just to make sure the linkage stays thoroughly operational and allowing the transmission to be properly maintained on the inside so that no passages inside the transmission ever have a chance of clogging up if you will because the first transmission should have never started to slip after 100k, that's ridiculous. Also just letting you tacoma owners know, my 2015 tacoma transmission was way overfilled and I contacted Toyota but they don't care!!!! I also noticed a slight bit of "wetness" developing on the backside of the transmission cover telling me that was caused by too much pressure from being way overfilled!!!!! It's as if it was done on purpose to eff up my transmission on purpose WTF!!!!!!!!!! But anyway I have my transmission service down to a science leveling the truck using a level on the transmission pan and a laser thermometer when to pull the level check plug.
Being from the north, first thing I thought of was rocking the car back-and-forth to get out of a snowbank. It’s a number one killer up here.
Shifting from reverse to drive without coming to a complete stop.
I had a friend I used to car pool with who had a 90s Pontiac Grand Am and he did this ALL the time! He'd back out of the parking space at work and immediately shift into drive.
Needless to say, he wound up having to buy a rebuilt transmission when his failed one day on the way home from work!
It was an old Pontiac lol like you said. It had probably nothing to do with it at all. If you don't replace oil regularly on old automatic transmission they will fail cause they literally rely on two propers in an oil pan.
In case of a emergency or no battery in some car like my Mazda CX 5 you can not move the shifter if the car is not running or have no more battery juice . so if you have to push the car you need to put the shifter in neutral . Like my cx 5 and in your CRV you can see it at 2 ,10 in your CRV . to the right of the shifter you have a little plastic panel about half of a inch. you lift this little panel and under that . you gone a have access to a pin you have to move to be able to reales the shifter freely . it happen to me in a parking airport in winter
A good tidbit we will all remember
I remember reading an operator manual (not everyone takes the time to read those, remember the folks who built your car probably know more about it than you or me). It told me to apply the parking brake before taking my foot off the driving brake (foot brake, brake pedal) and when it is certain the parking brake is holding the car then, and only then, put the car into PARK. Used to be the hand brake was actually intended to be an emergency brake but nowadays many of them are foot operated and are only for holding the car when stopped/parked. I actually regret spending time viewing your video,
Exactly why we old timers still call them the e-brake

Driving the vehicle downhill in Neutral does not do any harm to any part of engine or vehicle. It has one problem that you do not get engine braking. Otherwise your engine is disengaged from wheels and high speed of vehicle will not put any burden on the idling engine.
Avoid going downhill in Neutral only because you will not get any engine braking. L, L2, L1, 2, 1 are all designed for downhill drive in automatic vehicles.
Thanks for this..very important!the illustration was on point really helped me to have a better understanding so when i begin driving i'll always have that in my head
One Toyota mechanic popular on UA-cam advises not to change to N when stopped, claiming constant shifting will cause more wear. I always used to change to N when at lights etc, now not so sure.
بارك الله فيك أخي رامي، شرح مفيد وممتاز
I live in Canada, not I'm not sure of the new transmissions, but they only pump fluid in gear and N. So when I'm waiting on that long red light or train in winter or those hot days, e brake is on and vehicle in N so that transmission is still pumping fluid.
Do a video on different types of Automatic transmission 1.Torque Converter, 2.CVT, 3.DCT/ DSG 4. AMT, 5 IMT
My car as dsg video would be helpful 🙂
First, there's no such thing as Torque Converter gearbox as-is as a Torque converter is simply a part of a transmission that serves as a substitute for a clutch and flywheel in a manual transmission. Both CVTs (Continuously Variable Transmission or Variator) and ATs (Automatic Transmission) utilize a Torque Converter and both considered as "Torque Converter Transmissions".
On the other hand, AMT (Automated Manual Transmission) is essentially a regular Manual Transmission that gets it's clutch and the gear selector controlled by a mechanism which in turn is controlled by a computer. Whereas an IMT, just like AMT, is a Manual Transmission that has its Clutch controlled by a computerized mechanism whilst letting the driver freely select between gears. Note that AMT lets the user decide whether to use the Automated or Manual mode while iMT can only be controlled manually.

I'd probably settle for just using Park at a stop light or crossing. After all if you're turning the car off and on constantly, doesn't it stand to reason that it'll wear out your starter motor a lot faster?
@ 1:39 Stop at traffic light! Press the paddle brake and shift to N, continue pressing on the brake until you are ready to shift back to D and drive on as your foot will have to release the brake paddle and move to the accelerator paddle. Take note that you are also giving a signal to the car behind you that you are ready or not ready to drive on. Doing this will help when it rains or snowing when visibility is poor!
I don’t encourage switching off/on unless the car stop/start automatically as in later models. Reason being it will drain out battery power drastically to crank the engine. Newer model car uses high capacity AMG battery designed to accommodate electronic features in the car.
Does the automatic on off switch csuse damage to.the self starter?
This isn't good advice. There's no reason to shift to neutral. Connecting/disconnecting the transmission frequently can cause it to wear out quickly.
Give me a car without the automatic BS and let ME drive it. Manual hand brake should be required equipment in all vehicles (hand-operated).
@@HaroldBrice hahaha - so everyone should drive what you like? Sounds fair to me. BTW - why are you even watching a video on automatic transmissions?

Putting it into neutral doesn't affect the oil pump in the engine
There are a few things garbled or mixed up in this video. As to the engine getting starved for oil if you shift the transmission to neutral when going downhill: the engine oil pump is not at all affected by vehicle speed, only by rpm. The engine's lubrication needs, as well as its lubrication delivery, are solely determined by rpm, although there are other reasons why it's not a good idea to shift to neutral while going downhill, as you pointed out.
But the biggest goof is your explanation of what happens in an automatic transmission when you shift from a forward gear to a reverse gear or back again. I would suggest that you watch some videos on how a planetary gearset works (the heart of the automatic transmission). It is an amazing system! The gears are always in mesh and they always turn in the same direction - they never reverse! The amazing planetary gearset can provide various gear reductions, overdrive, direct drive, and reverse, all by simply locking different members to the case (or each other). In other words, by driving one member while taking power output from a different member. With a sun gear, ring gear, and planet gear carrier, this is all possible through the use of clutches or bands, which lock members together or to the transmission case (stationary). The clutches or bands are the components that might be damaged by rough shifting, although most transmissions for the last 50 years or so would not permit this. I enjoyed your video, though! (I used to teach this stuff!)
Can you shift on a Honda from drive into Sport mode while driving? Thank you
Yes, you can if you're talking about engaging the "Sport Mode" button. Sport resets the transmission computer to downshift more responsively. Better throttle performance with negligible extra fuel consumption.
I always put the car into "P" when stationary at a red light, a train crossing, or a non-moving traffic jam. It also removes the risk of the fuel pedal getting accidentally hit. I also pull the handbrake on first before putting it into "P". The worst thing you can do to an auto box is to rev up the moment to say 5000 rmp and then drop it into gear in order to smoke the tyres.
Old hot rods used to do this by dropping the gear into spin and putting it into gear, grinding the clutches.
Most times the gears were strong enough to handle this torment but these days, car gears are small and not strong enough to employ this tactic.
These days, you have to install a Dinan Chip with modified air intake and larger exhausts to make it run faster. Having modified engines allow the car to breathe more efficiently and run higher RPM using synthetic oil from Mobil or Castrol Synthetic.
Or better just order a Tesla with “Ludicrous “ mode and watch it go 0-60 in three seconds like a $2 million Porsche Twin Turbo Whale tail, or the lesser priced Nissan GT-R twin turbos, or the 1987 GM Grand National GNX.
it's better to put your lever in N instead of P when the engine is running and you want to stop only in traffic light. read about parking pawl.
Great video son!
UK Most cars are stick, coasting out of gear is illegal in the UK. Emergency brake? It will not stop the car because it bypasses the hydraulic master cylinder. UK known as Hand parking brake, manual box leave in gear for safety. Symple
I was interested to see what you had to say so I watched. To me these are all common sense. Shouldn't even have to think about not doing them. If you really value your car and especially the transmission you would not do these kinds of things. I never have. No one had to tell me to not do these things. Don't know why I automatically knew not to do them. Like I said. Just common sense.
It’s because you can feel the shifting after a while and easily recognize what is and isn’t healthy for your car, but not everyone is as intuitive and that’s fine. We all have our strengths and our weaknesses. Common sense to you might not be to someone else with totally different life experiences.
Thank you so much for the education on the Automatic Transmission.
Wouldn’t you put the car in neutral instead I mean that would make more sense instead of turning off the car at a stop light
Yes, neutral works good too
A cop in Youngstown AZ was chasing a another car that had just robbed a business and was fleeing. The road he was had an S turn that could only be driven through at low speed. The robber made it through, but the young officer forgot where he was and when he got to the turn he tried braking but it wasn’t enough, so he shifted through revers into park. The transmission exploded, leaving a huge hole in the transmission tunnel. The cop was lucky he was uninsured. He could have lost his leg doing something so stupid. This is why drag racers use transmission blankets, to keep fragments from a blown transmission out of the car.
my c5 Citroen requires me to put the brake pedal for changing gears (shifting).
That's Quite clever. Because pressing the brake pedal firmly requires the car to stop and this ensures that the gear does not change while moving. . Of course, you can put the lever to the left in manual mode and control the movement with heavy or light gear. i like it😑
They have thought of everything.
Another 'safety feature ' that makes drivers dumber
@@wilwert1746 that's not my design but why this future should makes driver dumb?
Anyway it needs a mechanism for moving lever from p position,so why not instead of pushing button on side of lever changer,with hand,push stop pedal and hit two targets with one bullet?!
The gears between forward (drive) and reverse are totally separate sets of planetary gears that are in constant mesh (never disengage) the band for drive tightens by a servo locking the outer drum of the planetary gears, the same in reverse, the drive band is loose & the servo on the reverse set of planetary gears tightens ! What happens if you do it while the car is moving is excess stress is put on bearings, bands, U-joints and other parts. Model T Fords have planetary gears controlled by foot pedals rather than servos controlled by oil pressure or electronics in newer cars. Google "planetary gears" and auto transmission servos for more info.

At the traffic light stop, isn't it better to shift the gear to Neutral and pull up the hand brake rather than shutting down the engine or shifting to park ? The owner's manual of my car clearly states:"Parking for a short time, shift gear to Neutral (N) and pull up hand brake. Do not press and hold the brake pedal in (D) or (R) even if you park for a short time as this will impair the service life of automatic transmission"
This is what i do at traffic light stop..
Yep, I've definitely been guilty of #1. Thanks for the warning.
Engine Lubrication is separate from transmission. In neutral downhill there is plenty of airflow to keep engine from overheating. HEMI's lack sufficient oil pressure at idle causing excessive cam wear and eventual misfire. Wonder how often the starter needs changing on the vehicles that shut down when idling?
When you have the pan cleaned, make sure they brush out the metal shavings and use a magnet, Jiffy Lube did not do this and it ruined the transmission. Expensive lesson!
Never park on an incline with weight of vehicle resting on park mode internal holding gear piece (which can eventually break that important part in the transmission). Engage parking brake first, put car in neutral & let weight of vehicle first rest on engaged parking brake, & then finally put transmission in park mode & turn it off.
I think this was a good video - so thanks. That said, I take exception to your statement that rolling downhill in N can overheat your engine. Simply false. I’m not saying your other reasons for not doing it aren’t valid, but if the engine is idling, the amount of oil being distributed through the engine is just fine. Engine heat comes from the friction of the pistons and other moving parts. When in N the engine is disengaged from the rest of the drivetrain - no addition heat is being generated than would be if it were idling at a stop. If anything, the engine will run cooler that it would at a stop due to the increased airflow.
Thank you for this info, also heard it is a big no no to tow an automatic car in the event of a breakdown.
Depends another on the make.Also the speeds and distance.
Thought I would learn something new, aw well.
Guess some people take the time to learn how a tool works, and some just stick to the basics. Must be the reason for all the new sensors and gadgets on new cars.
At the same time, you never stop learning. Bought a Subaru with all the gadgets, it’s nice but had to learn about the new gadgets. Parking in a hill using electronic brake before putting the car in park. You can feel the brakes engaging and taking pressure off transmission. No matter what, I still turn my wheels into the curb.
Well sir/ma'am you are one of the very few true drivers. Sadly these days they barely know how to start a car.
Sitting in park is harder on the transmition than drive. Any time the engine is running, the engine flywheel turns the torque converter body that drives the transmition fluid pump. This is a direct drive link no matter gear selected. When you idle in park the drive train holds the transmition input shaft so no other parts of the transmition are moving. The torque converter fins free wheel with no touching parts to wear or generate heat. In neutral or park the bans engage, gears spin, but the output gear disengages. This generates friction and heat. The fluid is air cooled so if you are not moving or fans running you are not cooling. sitting in park will increase wear and heat.
Hey, you live in Akron, when you were talking about don't coast down a hill. That road is portage path going into the valley. Stand Hewett is in the other direction. Cool, I notice that as you started down portage path's hill. Great job.
Makes perfect sense. I was driving my automatic like a manual and ruined it. Coasting in neutral, braking in drive and shifting into park to stop. It was "automatic" it wouldnt let you do something that you shouldnt, would it?
If Im waiting at traffic lights, I always put it in neutral with the handbreak on = less stress on the transmission & break light bulbs
