Also make sure that you put the car in neutral before putting on the handbrake, then put the car in park, otherwise the strain will still be on the gear and not on the brakes.
Awsome video. I have explained this to so many people. Trying to explain and tell them how little is holding their vehicle in place. this shows it perfectly. THANKS
I always shift to N, engage the parking brake, lift off the regular brake until the car "catches", then shift to P. It's a habit for me. Glad to know I'm doing it right.
I have convinced my relatives to first stop the car, press brake pedal, put it in neutral, apply parking brake, press brake pedal and THEN place the transmission on Park. I was pleased to see my dad doing that, some days ago, and said he´s pleased to have learned the correct way to park an automatic transmission vehicle. Since he began doing it this way, he never has felt any resistance when getting the selector out from the Park position.
as from my Pow. I almost never put my car E-brake (footbreak handbreak etc) when its WINTER, unless i'm going to use the car again soon or i'm in a very steep hill. Because in norway it gets cold and they use alot of salt on the roads... and a frozen break isnt cool :p and thats with experience from both Manual and Automatic transmisson ~,^ But this explanation is as clear and easy as it gets (y) Good work
I always use the E Brake on hills whether it's an auto or a manual. I've heard of cars being bumped into on a hill, shearing the mechanism for park, sending that car rolling down the hill.
Sheering? Eh, I am not so sure, these things are made of hardened steel. But it CAN however make it jump out of the gear tooth, which would result in the car rolling away.
Super helpful, many thanks. On my C4 I am consistently unable to get it out of Park when on an incline - so sensitive that it often happens even with the ebrake set (and I mean *really* set). Something is "binding" based on the lever binding against the gear. If I have someone gently rock the car forward the tranny will easily shift out of Park. Having studied the mechanical physics of how this thing works (thanks again for your video) I am struggling to imagine what is happening. I can not conjure in my mind a scenario where the mechanism would be bound such that the shifter will fail to move *out* of park. Do you have a guess for what I might be looking for when I pull the tranny apart? I am thinking a worn part (seems like always a reasonable guess...) or perhaps lose fasteners. What I am experiencing is definitely not reasonable. There is no way my car would have left a dealer's lot in 1965 with this behavior. My condition has degraded to the point that I don't let anyone else drive the car because they will get stuck very quickly (I deal with this multiple times a day).
Guys, the parking pin has more than enough strength to hold the car. Yes, when on a hill, you should definitely apply the parking brake, but if you live in the city and/or on relatively flat roads, putting it in park is sufficient. Anyone who uses the parking brake all the time is being excessive, and unnecessary. If the pin was any bigger, it would be MORE likely to break.
Yep, once while picking up parts I parked on a hill without the emergency brake, when I came out, the truck was at the bottom of the hill, luckily didn't hit anything except a fence post.
Haha no problem! Well I'm in last year of high school, and my thesis is about automatic transmission. I've been searching for Park mode, and thanks to that video I understood how it works, thanks for that!
+MattsMotorz Haha thanks! And yeah it's a bit difficult but I think it was worth all those months to learn about it... It's fascinating how it works :)
I accidently turned off my car in neutral so being new to automatic transmission I then shifted from neutral to park while engine was off and heard a clamping noise then started the car will it damage my car shifting between gears while engine is off ?
Then I can also replace the filter and fill up the trans fluid. Oh, this is a 1996. Another mechanic told me there may be a couple "valves" I may have to take out to get to the prawl pins... ???
I have the opposite problem: if I park where there is any pressure on the park prawl pin, then I can't get the truck out of park. If I put the emergency brake on before I put the vehicle in park though, then there is no pressure on the prawl and it shifts right out of park. Does anyone know what is worn? I was told I just need to replace the pin by dropping the pan pulling a couple pins on the prawl and replacing it. This is a chevy s10 with the L460 tranny.
+Neil P Bullock The transmission is a 4L60, not L460. I actually did a whole video series on how to rebuild that unit, so you could go through that and see where I get to the parking mechanism. I don't remember exactly how it went together as I did it a long time ago. I will say, check all linkages first before going into the transmission.
hi matt, i have been asking many professional and non can give me a correct answer or a convincing one. for auto transmission at neutral position what is moving and what is not moving at idle with the hand brake on?
The torque converter is moving, and perhaps a few shafts and gears, but that power is not transferred to the output shaft until a band or clutch pack is engaged. A more exact answer is impossible to get without asking for a specific model, as each transmission is different.
i have a question... normally the parking pawl and the parking gear are placed outside the other transmission gears ??, so that if the parking pawl breaks will not damage all the gearbox???
MrStefano218 Hmmm, that's a good question. I never payed much attention to parking pawl placement. Looking back on the transmissions I have worked on, I cannot say anything definitive. Sorry for the lame response! :\
MattsMotorz ok thanks , the question was referred to the fact that it happened whit my friend ... he has always had car whit manual transmissions , now he buy a new mazda 6 automatic , and while we were at about 20 Km/h , he shift in Parking, just for one second, as soon as he realized what was happening, he push back in Drive, we heard a noise like a gear running , but was not too loud and scary. The car does Not seem to have suffered damage , it is perfect , and the P position works perfectly ... the only concern is that, the contact between parking pawl and parking gear , has generated chip , fine metal particles in transmission oil... Can damage other transmission parts? Or these two components are made in hard steel, that not produces chip, fine metal particles ? the car is new has 2000 km....
When you engage the parking pawl while in motion, the pawl will just skip on the moving gear and not mesh. It is possible the tooth could chip while this is happening. I doubt it would produce fine metal particles, that is most likely from normal wear and tear. But I can't say 100% without seeing the particles.
***** Even though it would probably be fine, I always say it is good practice to do it all the time. Flat surfaces however will have very minimal load on the pawl.
The #1 thing I hate about my fellow Americans is the lack of using the parking brake in conjunction with the shifting to "P". There's a reason why every owner's manual recommend you use it....
If you accidentally shifted to park when vehicle is moving would it break the parking pawl gear? Thanks in advance to whoever will reply on this question.
Bro, i have a 2016 hilux ang there are times that when i shift out of park the shifter becomes hard and it feels like a metal to metal contact even on a flat surface. Sometimes i can shift out of park normally. My transmission shifts normally.
First thing I would do is remove the shifter linkage at the transmission and see if you can move the shifter lever (ON the transmission) by hand (with the car off and E brake on obviously).
I would have to see it, but if it looks strange replace it. It will probably be fine if you dont, but it is better to err on the side of caution when inside a transmission as if the part fails, you need to re-open it up to get to it.
Thats what I thought too!, but It seems to work fine, just want to err on the side of caution, I'm already into this rebuild 400.00 with tools I will only use once or twice!
Really the only tool you need with a 4L60E rebuild is the clutch spring compressor if I remember correctly. Watch my rebuild series on the 4L60E and you can see many of the tricks to get around the special tools.
MattsMotorz Thanks! I did watch several, I will watch them again, I am replacing all bushings and some will need the proper bushing installer, and I am going to use a press when I do this,(my dad has one for me to use) I like the way you do it with the wood, but I am worried I won't be as lucky, picked up a small bushing kit at Harborfreight for 18.00. but It will only do about 6 of the 13 bushings. gota go pawn shoppin and find a larger kit to do the rest. the biggest bushing is about 2.125 cant seem to find a decently priced kit for a reasonable price! UGHHH!
When you say "bushing kit" do you mean a bushing driver kit? Or an actual bushing kit? Because you can find the bushing kit for the transmission that has all the bushings you need for about 20 bucks. As far as bushing drivers, if you don't have the correct driver, just use a socket. Works just fine. In some cases if the bushing isn't recessed, you can even use the old bushing as a driver for the new one.
+Fabian De La Rosa Meaning you put it in park and the car still rolls? If there are no other transmission symptoms. there is definitely something wrong with the parking pawl linkage or pawl itself.
ok what i want to know is why my transmission not going into park now it goes into all the gears fine but when it in park the rear wheels spin freely i have a 97 mustang
There is no way to tell for sure without opening it up, but you most likely have an issue with the parking pawl itself. It is not unheard of for the pawl tooth to be sheared off (this could be caused by throwing it into park while the vehicle is moving) or it could be something with the pawl spring not allowing the pawl to be pushed into the final drive gear.
Lennart Stek my car would roll in park, it turns out my front axles were broken and I didn’t notice because they broke inside of the boot. I replaced the axles and the car was as good as new.
How come sometimes It feels like when I shift to park , the shifter feels like it is floating? Then it doesn't come outta park until I mess around with the shifter and car?
Also make sure that you put the car in neutral before putting on the handbrake, then put the car in park, otherwise the strain will still be on the gear and not on the brakes.
Awsome video. I have explained this to so many people. Trying to explain and tell them how little is holding their vehicle in place. this shows it perfectly. THANKS
Omg frl and then you get the “why do you use your E-Brake you drive an automatic” like bruh STFU learn your shit 😂😂
I always shift to N, engage the parking brake, lift off the regular brake until the car "catches", then shift to P. It's a habit for me. Glad to know I'm doing it right.
Uchendu Nwachukwu No your not, your being unnecessary. The pin is designed to hold the car in place, and can handle the weight of the car.
I do the same thing. I hate hearing that clunk.
Yeah it’s more satasfying then hearing the clunking noise
It isn't 100% necessary to do that when you are on relatively flat ground but it's good to take the load off the transmission.
@@MouseyBusiness
The BMW owners manual says that you need to use the parking brake even if you are on a flat road because there’s risk of movement.
I have convinced my relatives to first stop the car, press brake pedal, put it in neutral, apply parking brake, press brake pedal and THEN place the transmission on Park. I was pleased to see my dad doing that, some days ago, and said he´s pleased to have learned the correct way to park an automatic transmission vehicle. Since he began doing it this way, he never has felt any resistance when getting the selector out from the Park position.
I’m stoned right now and just thought to myself how does “PARK” work in a transmission?
Yes, high thoughts
Exactly

Thanks for that, my handbrake shoes are gone so was wondering what damage I was doing when parked on a slight hill.
I always use the E Brake on hills whether it's an auto or a manual. I've heard of cars being bumped into on a hill, shearing the mechanism for park, sending that car rolling down the hill.
Sheering? Eh, I am not so sure, these things are made of hardened steel. But it CAN however make it jump out of the gear tooth, which would result in the car rolling away.

I've been looking for the answer to what is Park mode everywhere, thank you!

Troll.
i mean if you have an electric p-brake why not just turn that on too
This video explanation, is exactly what I looked for 👍
And the real question is...how do you repair a broken one?
just the things i was looking for thanks a million
Yep, once while picking up parts I parked on a hill without the emergency brake, when I came out, the truck was at the bottom of the hill, luckily didn't hit anything except a fence post.
Thanks! I've been searching this for my thesis! :)
Graduate thesis? Masters? PhD? What is it about? (If you don't mind me asking.)
Haha no problem! Well I'm in last year of high school, and my thesis is about automatic transmission. I've been searching for Park mode, and thanks to that video I understood how it works, thanks for that!
7vinnie Oh! Good luck in writing! I would love to be able to write about this stuff for a grade lol.
+MattsMotorz Haha thanks! And yeah it's a bit difficult but I think it was worth all those months to learn about it... It's fascinating how it works :)
7vinnie You've got that right!
i have a c6 transmission 79 bronco. can i get to that gear. without taking down transmission? i think i broke the leaver that goes into the gear.
I accidently turned off my car in neutral so being new to automatic transmission I then shifted from neutral to park while engine was off and heard a clamping noise then started the car will it damage my car shifting between gears while engine is off ?
It is interesting. I always put my emergency brake on first :)
The parking pawl that you just showed, is it the same for vw dsg boxes or its a different mechanism?
Then I can also replace the filter and fill up the trans fluid. Oh, this is a 1996. Another mechanic told me there may be a couple "valves" I may have to take out to get to the prawl pins... ???
So what does it mean when it grinds for about 3 to 4 seconds when shifting to park?
I have the opposite problem: if I park where there is any pressure on the park prawl pin, then I can't get the truck out of park. If I put the emergency brake on before I put the vehicle in park though, then there is no pressure on the prawl and it shifts right out of park. Does anyone know what is worn?

Yes the torque converter is moving, as well as the pump rotor. Other than that, not much else is moving.

I doubt it would produce fine metal particles, that is most likely from normal wear and tear. But I can't say 100% without seeing the particles.
So it'd be all good if you decide to do this as well on a flat surface(rather than a hill or incline)?
***** Even though it would probably be fine, I always say it is good practice to do it all the time. Flat surfaces however will have very minimal load on the pawl.
Does the transmission oil circulate around the parking pawl and gear too?
Yup
The #1 thing I hate about my fellow Americans is the lack of using the parking brake in conjunction with the shifting to "P". There's a reason why every owner's manual recommend you use it....
well yeah you are usually required to press breaks to engage gear
So when the car rolls a bit is that the pawl just tightening up the slack?
Yup!
If you accidentally shifted to park when vehicle is moving would it break the parking pawl gear? Thanks in advance to whoever will reply on this question.
Usually what happens is the pawl skips on the teeth and doesn't break.

is it a easy fix?. I have no park in my 2000 dodge ram 2500 3/4 ton 4x4. any ideas
It is usually a big pain to get to the parking pawl. Sometimes the transmission needs to be removed completely.
what happens if you never ever use it? ive never used the handbrake in an automatic car before and nothing has happened to me?
It is pretty rare that something will actually happen. It is just good practice. Using the E-brake just takes some of the strain off the parking pawl.
I have a 99 f350 7.3 4x4 and is slipping on parking is any idea what can be??
+Fabian De La Rosa Meaning you put it in park and the car still rolls? If there are no other transmission symptoms. there is definitely something wrong with the parking pawl linkage or pawl itself.

Same issue, just had the trans out to replace front seal and reinstalled everything and now the car won't go into park
I have never heard of a parking pawl breaking , but is it possible?
It is pretty darn rare
Filmaker25 I'm pretty sure the one in my car is broken.
@@itsvoodoo7050 How do you notice this?

I bought car and wond stay on park car in park but if u give push it move
How come sometimes It feels like when I shift to park , the shifter feels like it is floating? Then it doesn't come outta park until I mess around with the shifter and car?
interesting, thank you...
Then it seems accidentally put in P while rolling 2mph in N won't hurt at all.
It most likely wouldn't hurt it at 2 mph, but it still isn't a good idea.

Should be fine. It happens.
