THE MOST detailed and clear explanation of this procedure. A few things have changed since this was published. There's an updated Mobil 1 trans fluid. Looks the same as the one he showed but it has a blue label. Still the LV ATF HP but less hydroscopic. Which is what was causing the shudder to begin with. There's also a lower temp range that GM put out. It's 93F - 113F. I use the higher range of 131F - 149F. That is now considered the track range.
My ATF fluid research has led me to discover the following information. I document it here as well as on several Wikipedia pages I created/modified on Dexron, Mercon, Mopar, and Toyota automatic transmission fluids. In 1967, Ford produced the Type-F fluid specification. The Type-F specification was intended to produce a "lifetime" fluid which would never need to be changed. This was the first of many Ford “lifetime” fluids. The 1974 Ford Car Shop Manual reads "The automatic transmission is filled at the factory with "lifetime" fluid. If it is necessary to add or replace fluid, use only fluids which meet Ford Specification M2C33F. Many other transmission manufacturers have followed with their own "Lifetime" automatic transmission fluids". GM's first "Lifetime" ATF was the Dexron-VI specification. How ATF Can Last a "Lifetime? To understand how a fluid can last a "lifetime", a study of the 1939 Chrysler Fluid Drive Fluid is helpful. The November 1954 edition of Lubrication Magazine (Published by The Texas Company, later known as Texaco) featured a story called "Evolution of the Chrysler PowerFlite Automatic Transmission." This article described the fluid used in the 1939 Chrysler Fluid Drive and its subsequent revisions and enhancements through 1954.'' A section of the feature described the lubrication of the Fluid Drive's fluid coupling, it reads ''"The fluid drive fluid coupling is partially filled with Mopar Fluid Drive Fluid, a special highly refined straight mineral oil with a viscosity of about 185 SUS at 100° F., excellent inherent oxidation stability, high viscosity index (100), excellent ability to rapidly reject air, very low natural pour point (-25° F.) , ability to adequately lubricate the pilot ball bearing and seal surface, and neutrality towards the seal bellows. '' The fluid operates under almost ideal conditions in what is essentially a hermetically sealed case, the small amount of atmospheric oxygen initially present is removed by a harmless reaction with the fluid so as to leave a residual inert (nitrogen) atmosphere. As a consequence it has not been necessary to drain and replace the fluid, and the level-check recommendation has been successively extended from the original 2,500 miles to 15,500 miles and finally to "never" - or the life of the car.'' ''Since drains and level checks were not only unnecessary but frequently harmful ( through the introduction of more air, and seal-destroying dirt) Chrysler eventually left off the tempting level inspection plugs. This mechanism is therefore one of the very few that is actually lubricated for the life of the car. There are now myriad examples of couplings that have operated well over 100,000 miles without any attention whatsoever and were still in perfect condition when the car was retired."'' The lesson learned by Chrysler with their fluid drives is applicable to modern automatic transmissions as well. Sealed Transmissions Any automatic transmission fluid will last longer if the transmission case could be hermetically sealed, but transmissions typically have two potential entry points for air: 1. The Dipstick Tube - Any transmission with a dipstick tube has the potential to let additional oxygen into the transmission through a dipstick that is not fully seated in the tube, or dipstick tube plug that is not fully seated. Even the process of checking the fluid level with a dipstick can allow additional oxygen and dirt into the transmission. Many modern transmissions do not have a dipstick, they have sealed transmission fluid level check plugs instead. By removing the traditional dipstick, the transmission manufacturer has also removed a potential entry point for oxygen; this reduces the potential for fluid oxidation. A sealed transmission will typically have longer transmission fluid life than a non-sealed transmission. 2. The Transmission Vent - Transmissions need vents to compensate for internal air pressure changes that occur with fluctuating fluid temperatures and fluctuating fluid levels during transmission operation. Without those vents, pressure could build resulting in seal and gasket leaks. Before the use of better quality base oil in ATF in the late 1990's, some older transmission breather vents contained a Transmission Air Breathing Suppressor (TABS) valve to prevent oxygen and water ingestion into their transmissions. Oxygen reacts with high temperature transmission fluid and can cause oxidation, rust, and corrosion. Automatic transmission fluids using lower quality base oil oxidized more easily than fluids using higher quality base oils. GM, and other transmission manufacturers now use smaller, remote mounted, breather vents specially designed to keep out water, but allow the a small amount of air movement through the breather as necessary. Sealed ATF Containers Any automatic transmission fluid will last longer if it comes from an unopened container 1. Use Sealed Containers - Containers storing automatic transmission fluid (ATF) should always be sealed; if exposed to the atmosphere, ATF may absorb moisture and potentially cause shift concerns. 2 '''Use New Fluid Only - When performing repairs on ATF equipped transmissions, it is important to use only new, clean ATF when refilling the transmission. Never reuse ATF. Example Maintenance Schedule GM Lifetime automatic transmission fluids made from higher quality base oil and an additive package are more chemically stabile, less reactive, and do not experience oxidation as easily as lower quality fluids made from lower quality base oil and an additive package. Therefore, higher quality transmission fluids can last a long time in normal driving conditions (Typically 100,000 miles (160,934 km) or more). The definition of 'Lifetime Fluid" differs from transmission manufacturer to transmission manufacturer. Always consult the vehicle maintenance guide for the proper service interval for the fluid in your transmission and your driving conditions. 2018 Chevrolet Colorado Example: According to the Scheduled Maintenance Guide of a 2018 Chevrolet Colorado with "Lifetime Fluid" could have two different fluid service intervals depending upon how the vehicle is driven: See my.chevrolet.com/learn/2018/Colorado 1. Normal Driving - Carry passengers and cargo within recommended limits on the Tire and Loading Information label - Driven on reasonable road surfaces within legal driving limits. Under "Normal" driving conditions, the automatic transmission fluid and filter never needs to be changed. 2. Severe Driving - Mainly driven in heavy city traffic in hot weather - Mainly driven in hilly or mountainous terrain - Frequently towing a trailer - Used for high speed or competitive driving - Used for taxi, police, or delivery service. Under "Severe" driving conditions, replace automatic transmission fluid and filter every 45,000 mi (72,420 km)
I was one of the 'shudder' 8-speed owners and it occured within the first year of ownership. The Mobil 1 fluid swap was done under warranty by the dealer and it immediately took care of the problem. Here I am down the road thinking about replacing the fluid as a preventive since I plan to keep this vehicle several more years with the current market on auto prices. Your video was extremely informative and much appreciated!
Everysingle time i watch one of your videos i feel i just came out of the classroom with very useful knowledge that is so powerful, yet strangely easy to learn and will be hard to forget... the way you explain everything makes so much sense, you my friend have GREAT TALENT! Thank you for all the lessons.
Thank you for the perfect explaining. Caution: the diff and the transmission use different fluid. Please note that: At min 15:00, John said there is (heat exchanger) inside the differential. Diff use: AC delco (DEXRON SAE 75W-90 GL-5 ) and that is not the transmission fluid. The fluids not get mix. Thank you
I hate to think this but as you explain these intricate procedures it makes me think there is hardly any way I could possibly get this detailed attention from even the "certified" technicians at any dealership.
I know what you mean, but I can tell you that there are some very good and talented technician's out there. I believe the problem lies with the flat rate pay system, it rewards technicians who take shortcuts and penalizes those who try to do everything correctly. The trick is to find a technician who cares enough to do it correctly.
I believe the fluid exiting the 10 speed transmission is actually reverse from the description of the 8 speed in this video. The fluid in the 10 speeds exit the transmission and flow to the two fluid coolers first (one in radiator and one aux plate type) then to the diff cooler and back to the transmission. This was a GREAT video! Thank You!
I'll add, that the Mobile 1 LV ATF HP is now, finally being send to all GM dealers to finally fix the shuddering AT of the Colorado. They are literally sending 55 gallon drums of this stuff along with a new Bosch tool kit to flush/decontaminate the transmission. What's frustrating is thousands of trucks have been in/out of shops for ongoing shuddering problems and here you are talking about the fix 18 months ago.
Awesome visual for us! I had a small town mechanic print papers and explain this all to me but to watch the video helps as well! My 2016 cadillac 8 speed has a shutter to it at 110k miles and I will be draining and replacing the fluid I drained here soon. I've never done it before but I'm ready!
This video is the definition of fucking awesome. So detailed, and the video is amazing quality. You sir, should make all the repair videos and service videos for every vehicle on planet earth.
i believe it was from people pouring in the wrong fluid and warranty coverages , as some shops have been known to use the wrong fluids also . so probably a combination of things .
8 speed is between 95-113 unless tracking and then its 131-149. The above 194 is only initially for trucks (thermal bypass valve), then bring back down to 95-113 for the check. Reading this directly out of the GM repair manual.
@@mofidgorgis2059 well, I already did a fluid change and filter. If it helps, I took my level from the crossmember on the frame right behind the tranny. And keep track of how much you take out, especially if it’s the 1st time being done. I think I was close because I brought it up to the temp for level check at my level measurement and it was a very slow tiny drip, just like you should have after the change. Overfill it by 1/2 quart, bring it up to temp and look for the same drizzle. 1,000 miles later and all is good.
I checked a 10 speed today. The service info does state to brake torque for only 10 sec with a 10 sec cool down and not to go over 1500 rpm. Also many gms now have a tft reading in the dic.
Best automotive shop teacher on the planet period!!! I've got the GMC Sierra with the dreaded transmission shudder and this puts everything into perspective. I've read nothing but good outcomes to those who submitted their vehicles for the fluid change under the TSB regarding this Mobil 1 change out. I will still buy GM products and this Camaro is awesome, I don't see any problem at all doing these little maintenance checks such as lifting the vehicle and being sure it's level. Besides, chicks love to watch guys "do stuff" and you never know, the girls in the neighborhood might be impressed with you working on your own car AND knowing what you're doing!! SUBSCRIBED AND HIT THE BELL NOTIFICATIONS, THANK YOU SIR!!!
Always first rate videos exposing all the details. Seems may more complicated than it should be, a strong argument to buy the manual version if an option.
This was exactly what I needed to know!! Thank you very much!! My respect for you 👌🏼 I know it takes a lot of work to film everything part by part. Once again, great video, and thanks!!!
WeberAuto hey I got a 2018 Chevy Colorado 2.8 diesel Hydra-Matic 6L50 six-speed automatic. What would the torque specs be on the transmission pan bolts. Also what would be the tightening pattern
In the video you said check the transmission fluid at 131 F-149 F, is that just for the Camaro? I have seen several places online saying check the fluid at temperatures of 95 F-113 F. Is this different for other vehicles? I drive a 2017 GMC Sierra Denali 6.2l 8l90 8speed M5U
Mr Kelly, Maybe you will agree with me? I chose the median temperature for my 6L50 trans. The service manual recommends opening the Check-Level Plug at 30C to 50C , so I picked 40C . My results were very good. I used a full syn Dex 6. Thanks for sharing your info.
I have a 2015 Escalade ESV with a 8L 90 and it smoked a torque converter on that factory fluid, so I would only go with the mobile one for any of these transmissions based on the fact that that factory filled fluid was the wrong fluid for these transmissions. GM just didn’t know it until it was too late. Great video!
Thats interesting to see on the camaro. I changed the fluid in my Corvette because of the shudder issue. I got the Mobil1 LV ATF HP with the blue label. This Video is from 2017 so it shows the older Mobil1 with black label. Great informations for everybody who drives these cars. Hope to see much more videos on your channel. Is there a special video from you about the reasons for the GM Converter Shudder problems? Greetings from Germany!!
Dear sir,, I have (FWD)4 speed conventional automatic sealed transmission and using dexron 6,,,what temperature for check the fluid level...im searching in manual book but no instructions for check transmission fluid. Thank's
Very very good. I remember other gms did this years ago. I also use to say jokingly you have to hop up and down on your left foot also to get it to work.
Just got new TC put in my 8 speed 8l45 chevy Colorado...Shudder returned after the fluid change. New Tsb coming out in Feb to change fluid to NEW again fluid they are putting out!! The color is BLUE.... It shifts fine now had shudder bad ...
Thanks for your feedback. The new fluid is not blue, the label on the new fluid bottle is blue and silver rather than the black and silver shown in this video..
Hey guy I have a question, I have a 2016 Camaro ss automatic 6 speed, I want to just change the fluid in my transmission, can I do that just drop the pan and change the filter on it, and is it 4 quart or 7.5 quart just to drop the pan?
Hello Prof. Kelly, brake torque @ partial throttle? I've done it many times over the years to help warm things up a bit. Maybe 1200, 1500 rpm, then let it idle in P or N for a minute or two to let things circulate and equalize a bit. Then a bit more if needed. Also I am not sure how many vehicles this is true of but in my 1999 Jeep GC park was not the same as neutral for checking fluid levels. as I recall the pump was not working in park so they specified N when checking fluid. Just some thoughts. George
Brake torquing can increase the fluid temperature inside the torque converter by 10 degrees F per second. at 300 degrees, the additives in the fluid start to boil off and all you have left is base oil. This will cause accelerated wear and overheating of the transmission.
Good question. My infrared temperature gun also came with a surface probe sensor that plugs into the gun and reads the temperature of whatever you touch it to. Many DVOMs come with a surface probe temp sensor as well.
You can check the transmission fluid temp in the car. Use the buttons on the steering wheel to navigate to performance then simply scroll to transmission temp.
If the temperature on the IR thermometer doesn't match the actual temperature due to the emissivity of the pan surface not matching what is assumed by the IR calibration, try putting a layer of black electrical tape on the pan as a target, which may have an emissivity closer to the usual 0.96 expected. Check the physical temperature against the reading, and if it matches closely, you could use the IR with better confidence. Some IR thermometers also allow the emissivity setting to be changed, within a limited range.
Really great engineering w/ confusing, different temperature requirements; not even a drain hole. Seems engineered to make money in the service department.
GM rarely put drain plugs in their transmission pans. It makes it very messy for a service technician who needs to remove the oil pan. I don't know why they did it that way, but it sure was not to help make it serviceable. Thanks for your feedback!
I'd suspect its because they may expect you to change the internal filter when you change the fluid, so by not having a drain plug, they try to force you to drop the pan to do the change, and if you went to the effort to drop the pan, you should change the filter while you are in there.
@@WeberAuto I like to weld a 1 X 1 X 1/4 piece of steel onto the pan and then drill and tap a 1/4 pipe plug. That way I only have to make a mess the first time.
Very helpful, I have a 2019 Colorado 2.5L I4 with 6L50. It seems like transmission is slipping at 25 and 35 mph especially in stop and go and/or slow moving traffic. This video helped me gain further insight to my transmission for when I go to the dealer to address under warranty.
On the old ZF transmissions (have a similar procedure as in this video), the temperature range is 30 to 50 degrees C. The problem with that is the transmission oil is too hot to test the level after a transmission service. After having my transmission serviced and watching the shop do the refill I was not happy with their filling procedure. I checked my own level at home starting with a cold transmission at 30 none came out by the time I got it full it was just below 50 (had to work quickly) and I had added about 0.7 l of fluid. So I was down on fluid. My question is what do you recommend shops do in this case? Do they have to tell the customer to leave the car there all day?
Great and clear video explanation. I've done exactly as explained here to my chevy trailblazer with 6L50 transmission. Fortunately, I can reach the side filling hole and extend it with hose to fill in the fluid. I flushed the whole fluid using internal pump as well.
Idk if it makes a difference but on my Colorado the transmission sits lower in the back than the front. And idk if they want the truck level or the transmission level when I check the fluid.
Wouldn't the transmission cooler stop the torque convert from over heating? Its my understanding that fluid from the converter goes straight to the heat exchanger then it is returned to the pan to repeat the process. A pickup truck with a max towing load can stay in stall for minutes at a time in normal driving conditions. How would a power braking do damage any significate damage?
With few exceptions, the cooler flow rate is less than is needed to keep up with the heat generation at full stall speed. Many pickup trucks have a Tow/Haul button on the shift lever. In the Tow/haul mode several strategies are used to prevent overheating the torque converter. Typically the Tow/Haul mode prevents towing in the overdrive gear ranges. That makes it harder to reach full stall speed while driving. The transmission control module also have two modes of heat reduction. 1. The "Hot Mode" engages the torque converter clutch to stop any heat generation inside the torque converter. This mode continues until the fluid temperature drops to an acceptable level. 2. "Super Hot Mode" signals the driver to stop the vehicle and idle the engine to allow the transmission fluid to circulate through the cooler until an acceptable temperature is reached. Stopped or while driving; taking the torque converter to its maximum stall speed can bring the fluid temperature above 300 degrees F and ruin the fluid. once the fluid reaches 500 degrees F, the steel housing of the torque converter will start to turn blue. Remember that the fluid temperature can rise 10 degrees F per second at full stall speed. it would only take 30 to 60 seconds to reach a damaging temperature. Transmission coolers extend that time period, but excessive operation at full stall speed will ruin your transmission.
Can you explain or show the Trans Cleaning Procedure that flushes clutch solinoids and pressure regulators using GM software or other tuning /scanner software such as HP tuners
Let you know that GM is currently shipping (free of cost) a bosch Trans cleaning system and 55 gallon drums of Mobile 1 LV ATF HP to every dealership. They will have the tool kits probably by Feb end. I think allot of the problem with prior repairs was improper cleaning. But there is a new update from this month to all dealerships. I actually have a copy of it and its happening. Hopefully will finally resolve the shuddering 8 speed problems. This may be different from what your talking about but its relevant to fixing the issues with the 8 speed.
I have a Cadillac cts vsport with the 8speed Asian transmission I had the dealership drop the pan and replace the filter and refill twice now in 8th gear when at operating temperature I get hesitation. Does that sound like they didn’t fill it correctly? It’s definitely not spark plugs or coils
How do I know if it is overfilled? I had the trans temp sensor replaced and a service done. A week later my trans doesn’t want to shift. RPMS shoot up and shifts hard.
"Brake torquing"... The converter is a fluid coupling device. In operation, climbing a hill in sf that takes you 3+ minutes creates significant equivalent brake torquing. Driving the windy mountain pass through berryessa where speeds are low enough that the tcc stays unlocked, performs the same "brake torquing" action. Being in gear, while stopped, is brake torquing. Different levels of loading, but all do the same thing. This is the reason converters arent air cooled anymore. Also why a lot of performance cars come with external coolers as well. I dont see any reason that "brake torquing" to heat the trans fluid would be a problem so long as you were monitoring the temp with a scantool.
Good point, but everything has limits. The difference is brake torquing takes the engine rpm to the stall speed of the torque converter and keeps it there (10 degrees F rise per second). Driving on roads and conditions as you have described may not always keep the engine at maximum stall speed. If it did, it would cause the same damage as brake torquing. Every vehicle has a maximum towing capacity and hauling capacity. If you exceed that capacity, expect an overheated transmission. A scan tool typically shows the sump (pan) fluid temperature, not the temperature of the fluid leaving the torque converter (through the oil pump) and heading to the transmission cooler. When the transmission fluid reaches a temperature above the normal 220F - 250F range, some of the blended fluid additives in ATF can begin to evaporate. This effectively kills the transmission fluid and eventually the transmission. Thanks for your feedback.
Unfortunately I have seen it happen too many times. Keep in mind that most stock torque converters have a stall speed between 1800 and 2400 RPM. Going to wide open throttle is not necessary to reach stall speed. A light throttle to 2500 rom would do it. Thanks again for your feedback. Have a great day!
Stop and go city driving should have it there after 15-20 minutes of driving. High speed driving will lock the converter clutch and stop heat generation. Thanks for watching
2013 Camaro v6 automatic the trans started slipping pretty bad at stop signs yesterday. Today it won’t even drive so I’m guessing somehow my fluid has leaked out? I’m going to try to add some today.
My 2013 ss has had a steady stream for over 5 min... started fast, slowed to a very thin drizzle(not a drip)... did a pain drop filter and fluid change... can not get it to just drip
Great question. It has never been touched. It was slightly overfilled at the factory. The fluid that came out equaled about 0.355L or 12 fluid ounces (0.375 quart). The drain hole is so small that it appeared to drain more than it actually did.
WeberAuto quick question ive just turned 18 and i am looking at a pontiac G8 with the 6L80e. It has 132xxx miles. I read on forums these trans arent all that reliable. So now i must ask you what your opinion is on these G8 trans. Thanks -Flow
Where did you get the temperature range for the fluid level check? I've been trough the forums and the temperature is different as the one you said "The transmission fluid level must be checked when the transmission fluid temperature (TFT) is between 35-45°C (95-113°F)." static.nhtsa.gov/odi/tsbs/2019/MC-10163890-9999.pdf I did according to your video but now i'm in doubt if thats the correct temperature to check the level.
Great video! Question: I have a 2019 Silverado - 8L90 with 38k miles and about to have the trans fluid maintenance done. Called a couple Chevy dealerships: 1) 1st one, they would drop the pan, change the filter & gasket then refill, 2) another dealership suggests only doing a drain and fill with no new filter & gasket and finally, 3) last dealership recommends a flush (not drain and fill) with no new filter & gasket. I am sooo confused as to what to do. I have heard to NOT do flushes these days. Thoughts Please and recommendations.
Question: I have what's believe to be the 6L90 but have torque shutter, can the mobile 1 synthetic LV ATF HP be used or best to still use the Decron-VI recommended for the 6 speed?
Great video I do have an honest question that I hope someone could answer in regards to a 2013 Camaro ZL1 with the 6L90 transmission . AC Delco makes both a conventional and fully synthetic version of Dexron VI. Is there any disadvantage in using the synthetic version of dexron VI in the 6L90 transmission. I have had numerous people tell me just use the conventional Dexron VI and do not use the synthetic version but nit a verified reason as to why? Even when searching if this item will work in my vehicle most places show NOT Compatible?? Have there been issues putting the the synthetic version of the Dexron VI in the 6L90. My transmission only has 45K so if its because of the thinking of it could cause slipping if the clutch packs are worn then maybe but it seems to be OK. Just looking for a honest and educated and technical answer as to why i should not use the sythetic version of the Dexron VI since its made by Ac Delco. Would like only professional people to advise. Thanks for an info you can give
All GM Licensed Dexron VI is the same, there is not a conventional version and a synthetic version. GM Licensed Dexron VI has always been made from "Synthetic" base stock oil (which can be a group 4 PAO or a Group 3+). Licensed fluids will have a license number on the that begins with the letter "J". There is a lot of aftermarket, non-licensed fluids out there claiming to be compatible, meet or exceed standards, etc, but I would not use anything but the original licensed factory recommended fluid in that car. I made a video on the problem of misleading labels and claims on automatic transmission fluids, even from ACDelco. See ua-cam.com/video/xUFY0L_zFek/v-deo.html
Hey great video. 1 question about the 8spd transmissions. there was mention of changing oil to the specific Mobil 1 oil if there was an issue with torque converter shutter. Would you suggest it may be a good idea to preemptively switch to that special Mobil oil as a preventative action so you don't get the toque converter shutter in the first place? Also do you know why they suggested this a a fix? like whats the difference between the oils anyways ?
If it were my vehicle I would switch to the newer fluid. Both fluids are comprised of a fully synthetic PAO base oil, but the Mobil fluid has a different additive package to reduce torque converter clutch shudder.
@@WeberAuto I currently have a Colorado in production as I type this. Asked my sales manager if they are using this mobile 1 in new builds. Said nope. Only those with shudder. GM sending out 55 gallon drums to all dealers along with new Bosch tool kit to flush/decontaminate transmission. But told me my new truck will still have old fluid. I will press them to put the new fluid. The best time is when the truck is new. Does this stuff cost allot more? Why is GM not using this on new production?
@@WeberAuto GM refuses to use on truck that is currently in production. Dealer will not apply it until there is a problem. And the dealer told me that 20 percent are having the issue at some point. I'm hoping GM will refund my deposit under the circumstances. But I can't accept this order and will not accept the truck any longer. I am also not willing to pay 500 dollars on a brand new truck to have the fluids replaced. This whole experience has not been good and GM should have started to use this back when you put this video out. 18 months ago. Wow. No, they would rather customers, one by one, experience the shudder, damage the Torque convertor, then have to bring into service etc... and go through all that then to just put the fluid into new production. I can't and won't support a company that acts like this. Not even remotely so. Update. I'm hearing GM is finally starting to use the new fluid in new production. Early reports say its having good results in fixing the problem. So if you buy a new Colorado just make sure it has a build date on March 2019 or after. Avoid all models before that. Because the dealers won't do the fluid flush unless you can PROVE its having the issue. And that is not always easy thing to do. So best just avoid it if you can. Also my two cents is just buy a Frontier Pro 4X. The VQ40 24 valve DOHC with 5 speed OD is still the best motor/trans tune by far. And the ergonomics are better then the GM. Better seats, more comfortable and 8 way power. Also has sunroof, real locker, 31 inch all terrain with dual climate control etc... loaded. And it will cost 5 thousand less then the GM and will be rolling around for years after the GM truck is rusting out in the junk yard. Just not worth the trouble. GM has been struggling for years with their mid size.
good evening , very well spoken representation and broad approach for more than one application all in one video. thank you very much for your time and informational video. the gentleman of tech
Thank you for the instructional video Sir. My question is, what computer and or equipment did you use to monitor the transmission fluid temperature ? Any help would be soo appreciated Sir.
That side fill plug is a bear to get to, but not very difficult as described. The heat shield bolts covering it is difficult to get to. The 2nd time, I was able to reach over the heat shield, down to the plug with ease. I would never remove the heat shield the 2nd time, but the first time it is near critical.
could you please explain why when the transmission system when get over than 80,000 KM on my 2012 chevy cruze we can't change the oil because there is a chance for damage it
Hi, The recommended service interval for your transmission is every 156,000 km. Changing the fluid before that will not hurt anything as long as the person changing the fluid does it properly at the correct fluid temperature and with the correct fluid. Best wishes.
Sir... ive a question. when you compare this pan to the Toyota pan you had on ("Toyota Transaxle Fluid Level Check - No Dipstick" on Apr 14, 2015). which one is shallower? looking at height of the leveling standpipe, the normal fluid level would be "higher" than the depth of this pan. if that is the case, i would think it will leak over time when cold. esp after a pan removal.
This pan is more shallow. Pan depth does not tell the full story, you must consider length and width for overall volume and stand pipe height calculations.
Here 6 years later watching this video. Very well done. Thank you.
THE MOST detailed and clear explanation of this procedure. A few things have changed since this was published. There's an updated Mobil 1 trans fluid. Looks the same as the one he showed but it has a blue label. Still the LV ATF HP but less hydroscopic. Which is what was causing the shudder to begin with. There's also a lower temp range that GM put out. It's 93F - 113F. I use the higher range of 131F - 149F. That is now considered the track range.
My ATF fluid research has led me to discover the following information. I document it here as well as on several Wikipedia pages I created/modified on Dexron, Mercon, Mopar, and Toyota automatic transmission fluids.
In 1967, Ford produced the Type-F fluid specification. The Type-F specification was intended to produce a "lifetime" fluid which would never need to be changed. This was the first of many Ford “lifetime” fluids. The 1974 Ford Car Shop Manual reads "The automatic transmission is filled at the factory with "lifetime" fluid. If it is necessary to add or replace fluid, use only fluids which meet Ford Specification M2C33F. Many other transmission manufacturers have followed with their own "Lifetime" automatic transmission fluids". GM's first "Lifetime" ATF was the Dexron-VI specification.
How ATF Can Last a "Lifetime?
To understand how a fluid can last a "lifetime", a study of the 1939 Chrysler Fluid Drive Fluid is helpful. The November 1954 edition of Lubrication Magazine (Published by The Texas Company, later known as Texaco) featured a story called "Evolution of the Chrysler PowerFlite Automatic Transmission." This article described the fluid used in the 1939 Chrysler Fluid Drive and its subsequent revisions and enhancements through 1954.''
A section of the feature described the lubrication of the Fluid Drive's fluid coupling, it reads ''"The fluid drive fluid coupling is partially filled with Mopar Fluid Drive Fluid, a special highly refined straight mineral oil with a viscosity of about 185 SUS at 100° F., excellent inherent oxidation stability, high viscosity index (100), excellent ability to rapidly reject air, very low natural pour point (-25° F.) , ability to adequately lubricate the pilot ball bearing and seal surface, and neutrality towards the seal bellows. ''
The fluid operates under almost ideal conditions in what is essentially a hermetically sealed case, the small amount of atmospheric oxygen initially present is removed by a harmless reaction with the fluid so as to leave a residual inert (nitrogen) atmosphere. As a consequence it has not been necessary to drain and replace the fluid, and the level-check recommendation has been successively extended from the original 2,500 miles to 15,500 miles and finally to "never" - or the life of the car.''
''Since drains and level checks were not only unnecessary but frequently harmful ( through the introduction of more air, and seal-destroying dirt) Chrysler eventually left off the tempting level inspection plugs. This mechanism is therefore one of the very few that is actually lubricated for the life of the car. There are now myriad examples of couplings that have operated well over 100,000 miles without any attention whatsoever and were still in perfect condition when the car was retired."'' The lesson learned by Chrysler with their fluid drives is applicable to modern automatic transmissions as well.
Sealed Transmissions
Any automatic transmission fluid will last longer if the transmission case could be hermetically sealed, but transmissions typically have two potential entry points for air:
1. The Dipstick Tube - Any transmission with a dipstick tube has the potential to let additional oxygen into the transmission through a dipstick that is not fully seated in the tube, or dipstick tube plug that is not fully seated. Even the process of checking the fluid level with a dipstick can allow additional oxygen and dirt into the transmission. Many modern transmissions do not have a dipstick, they have sealed transmission fluid level check plugs instead. By removing the traditional dipstick, the transmission manufacturer has also removed a potential entry point for oxygen; this reduces the potential for fluid oxidation. A sealed transmission will typically have longer transmission fluid life than a non-sealed transmission.
2. The Transmission Vent - Transmissions need vents to compensate for internal air pressure changes that occur with fluctuating fluid temperatures and fluctuating fluid levels during transmission operation. Without those vents, pressure could build resulting in seal and gasket leaks. Before the use of better quality base oil in ATF in the late 1990's, some older transmission breather vents contained a Transmission Air Breathing Suppressor (TABS) valve to prevent oxygen and water ingestion into their transmissions. Oxygen reacts with high temperature transmission fluid and can cause oxidation, rust, and corrosion. Automatic transmission fluids using lower quality base oil oxidized more easily than fluids using higher quality base oils. GM, and other transmission manufacturers now use smaller, remote mounted, breather vents specially designed to keep out water, but allow the a small amount of air movement through the breather as necessary.
Sealed ATF Containers
Any automatic transmission fluid will last longer if it comes from an unopened container
1. Use Sealed Containers - Containers storing automatic transmission fluid (ATF) should always be sealed; if exposed to the atmosphere, ATF may absorb moisture and potentially cause shift concerns.
2 '''Use New Fluid Only - When performing repairs on ATF equipped transmissions, it is important to use only new, clean ATF when refilling the transmission. Never reuse ATF.
Example Maintenance Schedule
GM Lifetime automatic transmission fluids made from higher quality base oil and an additive package are more chemically stabile, less reactive, and do not experience oxidation as easily as lower quality fluids made from lower quality base oil and an additive package. Therefore, higher quality transmission fluids can last a long time in normal driving conditions (Typically 100,000 miles (160,934 km) or more). The definition of 'Lifetime Fluid" differs from transmission manufacturer to transmission manufacturer. Always consult the vehicle maintenance guide for the proper service interval for the fluid in your transmission and your driving conditions.
2018 Chevrolet Colorado Example:
According to the Scheduled Maintenance Guide of a 2018 Chevrolet Colorado with "Lifetime Fluid" could have two different fluid service intervals depending upon how the vehicle is driven: See my.chevrolet.com/learn/2018/Colorado
1. Normal Driving
- Carry passengers and cargo within recommended limits on the Tire and Loading Information label
- Driven on reasonable road surfaces within legal driving limits.
Under "Normal" driving conditions, the automatic transmission fluid and filter never needs to be changed.
2. Severe Driving
- Mainly driven in heavy city traffic in hot weather
- Mainly driven in hilly or mountainous terrain
- Frequently towing a trailer
- Used for high speed or competitive driving
- Used for taxi, police, or delivery service.
Under "Severe" driving conditions, replace automatic transmission fluid and filter every 45,000 mi (72,420 km)

I skimmed it and found nothing of importance. Which ones take ULV?
I was one of the 'shudder' 8-speed owners and it occured within the first year of ownership. The Mobil 1 fluid swap was done under warranty by the dealer and it immediately took care of the problem. Here I am down the road thinking about replacing the fluid as a preventive since I plan to keep this vehicle several more years with the current market on auto prices. Your video was extremely informative and much appreciated!
Everysingle time i watch one of your videos i feel i just came out of the classroom with very useful knowledge that is so powerful, yet strangely easy to learn and will be hard to forget... the way you explain everything makes so much sense, you my friend have GREAT TALENT! Thank you for all the lessons.
Thank you for the perfect explaining.
Caution: the diff and the transmission use different fluid. Please note that:
At min 15:00, John said there is (heat exchanger) inside the differential.
Diff use: AC delco (DEXRON SAE 75W-90 GL-5 ) and that is not the transmission fluid.
The fluids not get mix.
Thank you
I hate to think this but as you explain these intricate procedures it makes me think there is hardly any way I could possibly get this detailed attention from even the "certified" technicians at any dealership.
I know what you mean, but I can tell you that there are some very good and talented technician's out there. I believe the problem lies with the flat rate pay system, it rewards technicians who take shortcuts and penalizes those who try to do everything correctly. The trick is to find a technician who cares enough to do it correctly.
I agree bro. Two mechanics have told me they’ll just drop the pan :-|
You are correct, sir
@@WeberAutoWell said and unfortunately the truth.
Just listen to them explain things like he is after you ask questions.
I LOVE how well put together this presentation is, keeping things nice and simple and to the point!!!!
Thanks so much!
This video was so informative I actually watching the entire thing! Thank You!
I believe the fluid exiting the 10 speed transmission is actually reverse from the description of the 8 speed in this video. The fluid in the 10 speeds exit the transmission and flow to the two fluid coolers first (one in radiator and one aux plate type) then to the diff cooler and back to the transmission.
This was a GREAT video! Thank You!
I’ve learned more from this video than the 6 months I’ve spent as a lube tech at a dealership. Thank you.
Dude, you rock!
Please don’t stop doing what you’re doing. EXCELLENT explanation!
Genious idea with the trans fluid! From level, to all the specific fluids for every different trans, just crazy!
Thanks for your feedback
I'll add, that the Mobile 1 LV ATF HP is now, finally being send to all GM dealers to finally fix the shuddering AT of the Colorado. They are literally sending 55 gallon drums of this stuff along with a new Bosch tool kit to flush/decontaminate the transmission. What's frustrating is thousands of trucks have been in/out of shops for ongoing shuddering problems and here you are talking about the fix 18 months ago.
Just successfully completed a fluid change thanks to this video. Thanks so much, awesome teacher your students are very lucky.
Awesome visual for us! I had a small town mechanic print papers and explain this all to me but to watch the video helps as well! My 2016 cadillac 8 speed has a shutter to it at 110k miles and I will be draining and replacing the fluid I drained here soon. I've never done it before but I'm ready!
I appreciate the time you took to make this video. Very well spoken and easy to understand. Well done !
I just saved so much money learning this from you. Thank you.
This video is the definition of fucking awesome. So detailed, and the video is amazing quality. You sir, should make all the repair videos and service videos for every vehicle on planet earth.
Perfect video. Exactly what I was looking for. I have heard they are making a dipstick mod for these now. Why they ever took that away is beyond me!
i believe it was from people pouring in the wrong fluid and warranty coverages , as some shops have been known to use the wrong fluids also . so probably a combination of things .
8 speed is between 95-113 unless tracking and then its 131-149. The above 194 is only initially for trucks (thermal bypass valve), then bring back down to 95-113 for the check. Reading this directly out of the GM repair manual.
For those of us without a lift…. Where should i place my level after jacking up my truck (with 8l90) to assure the vehicle is level?
I have the same question
@@mofidgorgis2059 well, I already did a fluid change and filter. If it helps, I took my level from the crossmember on the frame right behind the tranny. And keep track of how much you take out, especially if it’s the 1st time being done. I think I was close because I brought it up to the temp for level check at my level measurement and it was a very slow tiny drip, just like you should have after the change. Overfill it by 1/2 quart, bring it up to temp and look for the same drizzle. 1,000 miles later and all is good.
@@meschker0507 Thank you 👍
This guy is the real deal. Thank you. Excellent video
You are highly knowledgeable and well fluent in explaining this type of transmission. Surpurb!!!
Very detailed explanation. This explains a lot about why the manual says to take it to a dealer.
I checked a 10 speed today. The service info does state to brake torque for only 10 sec with a 10 sec cool down and not to go over 1500 rpm. Also many gms now have a tft reading in the dic.
Good to know, thank you
Excellent video, just a question my camaro shows the transmission temperature on the cluster can I use that reading for the level checking procedure?
Best automotive shop teacher on the planet period!!! I've got the GMC Sierra with the dreaded transmission shudder and this puts everything into perspective. I've read nothing but good outcomes to those who submitted their vehicles for the fluid change under the TSB regarding this Mobil 1 change out. I will still buy GM products and this Camaro is awesome, I don't see any problem at all doing these little maintenance checks such as lifting the vehicle and being sure it's level. Besides, chicks love to watch guys "do stuff" and you never know, the girls in the neighborhood might be impressed with you working on your own car AND knowing what you're doing!! SUBSCRIBED AND HIT THE BELL NOTIFICATIONS, THANK YOU SIR!!!
Always first rate videos exposing all the details. Seems may more complicated than it should be, a strong argument to buy the manual version if an option.
Thank you. There's so much information lacking from every other post I've seen
This was exactly what I needed to know!! Thank you very much!! My respect for you 👌🏼 I know it takes a lot of work to film everything part by part. Once again, great video, and thanks!!!
Thank you!
WeberAuto hey I got a 2018 Chevy Colorado 2.8 diesel Hydra-Matic 6L50 six-speed automatic. What would the torque specs be on the transmission pan bolts. Also what would be the tightening pattern
Very thorough video. This was perfect for the CT6 I am servicing.
Glad to hear
You helped a ton before I service my truck 8sp. And you saved me from going out and buying the wrong fluid.Thanks and did hit the Sub button.
Thank you!
As usual, your video is top notch. As usual, automakers extreme overengineering makes me fly into a rage...
Not talking about the blue label mobil 1 ?
That came out after this video was shot. Yes, use Blue label instead of black label. Thanks for watching
In the video you said check the transmission fluid at 131 F-149 F, is that just for the Camaro? I have seen several places online saying check the fluid at temperatures of 95 F-113 F. Is this different for other vehicles? I drive a 2017 GMC Sierra Denali 6.2l 8l90 8speed M5U
Yes, just for Camaro
@@WeberAuto do you know what the temperature is for a 2017 GMC Sierra M5U?
Would it be possible to clean the area and remove the side fill plug while cool and then condition the transmission with the plug open?
Yes, if you can get to it
Mr Kelly, Maybe you will agree with me? I chose the median temperature for my 6L50 trans. The service manual recommends opening the Check-Level Plug at 30C to 50C , so I picked 40C . My results were very good. I used a full syn Dex 6. Thanks for sharing your info.
Sounds good. Thank you
I have a 2015 Escalade ESV with a 8L 90 and it smoked a torque converter on that factory fluid, so I would only go with the mobile one for any of these transmissions based on the fact that that factory filled fluid was the wrong fluid for these transmissions. GM just didn’t know it until it was too late. Great video!
Were you the original owner of the caddy?
Thank you very much for the video, I just changed the ATF + filter for my 2010 CTS V and I knew what to look for thanks to your video.
Thats interesting to see on the camaro. I changed the fluid in my Corvette because of the shudder issue. I got the Mobil1 LV ATF HP with the blue label. This Video is from 2017 so it shows the older Mobil1 with black label.
Great informations for everybody who drives these cars. Hope to see much more videos on your channel. Is there a special video from you about the reasons for the GM Converter Shudder problems?
Greetings from Germany!!
What about the angle of the sump when checking? Bottom of sump exactly horizontal or when the car is in a specific condition?
No, the car has to be level. The angle of the sump is not important. Thanks for your feedback
Dear sir,,
I have (FWD)4 speed conventional automatic sealed transmission and using dexron 6,,,what temperature for check the fluid level...im searching in manual book but no instructions for check transmission fluid. Thank's
Very very good. I remember other gms did this years ago. I also use to say jokingly you have to hop up and down on your left foot also to get it to work.
LOL, yes, thank you
Just got new TC put in my 8 speed 8l45 chevy Colorado...Shudder returned after the fluid change.
New Tsb coming out in Feb to change fluid to NEW again fluid they are putting out!!
The color is BLUE....
It shifts fine now had shudder bad ...
Thanks for your feedback. The new fluid is not blue, the label on the new fluid bottle is blue and silver rather than the black and silver shown in this video..
See. How much I know..So bottle is blue not fluid!!
Thanks
Why don’t they just use a sight glass for level? I have seen those used on industrial equipment and they are great!
Good question, thanks you!
to easy for consumer , as a dealership makes the real money from service work .
Hey guy I have a question, I have a 2016 Camaro ss automatic 6 speed, I want to just change the fluid in my transmission, can I do that just drop the pan and change the filter on it, and is it 4 quart or 7.5 quart just to drop the pan?
?
Need help
@@georgeluna8050 Hey guy? WTF dude? Show some respect.
Hello Prof. Kelly, brake torque @ partial throttle? I've done it many times over the years to help warm things up a bit. Maybe 1200, 1500 rpm, then let it idle in P or N for a minute or two to let things circulate and equalize a bit. Then a bit more if needed. Also I am not sure how many vehicles this is true of but in my 1999 Jeep GC park was not the same as neutral for checking fluid levels. as I recall the pump was not working in park so they specified N when checking fluid. Just some thoughts.
George
Brake torquing can increase the fluid temperature inside the torque converter by 10 degrees F per second. at 300 degrees, the additives in the fluid start to boil off and all you have left is base oil. This will cause accelerated wear and overheating of the transmission.
Wonder if there are other ways of accurately determining transmission fluid temperature without the use of factory scan tool?
Good question. My infrared temperature gun also came with a surface probe sensor that plugs into the gun and reads the temperature of whatever you touch it to. Many DVOMs come with a surface probe temp sensor as well.
You can check the transmission fluid temp in the car. Use the buttons on the steering wheel to navigate to performance then simply scroll to transmission temp.
If the temperature on the IR thermometer doesn't match the actual temperature due to the emissivity of the pan surface not matching what is assumed by the IR calibration, try putting a layer of black electrical tape on the pan as a target, which may have an emissivity closer to the usual 0.96 expected. Check the physical temperature against the reading, and if it matches closely, you could use the IR with better confidence.
Some IR thermometers also allow the emissivity setting to be changed, within a limited range.
What an exhausting process...but thank you for explaining it!
Lol
Great video thank you.
Not sure what the heck GM was thinking. There was nothing wrong with the conventional dipstick / fill plug / drain plug design.
Really great engineering w/ confusing, different temperature requirements; not even a drain hole. Seems engineered to make money in the service department.
GM rarely put drain plugs in their transmission pans. It makes it very messy for a service technician who needs to remove the oil pan. I don't know why they did it that way, but it sure was not to help make it serviceable. Thanks for your feedback!
I'd suspect its because they may expect you to change the internal filter when you change the fluid, so by not having a drain plug, they try to force you to drop the pan to do the change, and if you went to the effort to drop the pan, you should change the filter while you are in there.
@@KSSilenceAU Yes, because no one swaps an oil filter because there is a drain plug. This is just a case of GM being a PITA.
@@WeberAuto I like to weld a 1 X 1 X 1/4 piece of steel onto the pan and then drill and tap a 1/4 pipe plug. That way I only have to make a mess the first time.
I have done research and I have seen that the mobil 1 blue label is recommended not the black label. Any new update we should know about?
Very helpful, I have a 2019 Colorado 2.5L I4 with 6L50. It seems like transmission is slipping at 25 and 35 mph especially in stop and go and/or slow moving traffic. This video helped me gain further insight to my transmission for when I go to the dealer to address under warranty.
On the old ZF transmissions (have a similar procedure as in this video), the temperature range is 30 to 50 degrees C. The problem with that is the transmission oil is too hot to test the level after a transmission service. After having my transmission serviced and watching the shop do the refill I was not happy with their filling procedure. I checked my own level at home starting with a cold transmission at 30 none came out by the time I got it full it was just below 50 (had to work quickly) and I had added about 0.7 l of fluid. So I was down on fluid. My question is what do you recommend shops do in this case? Do they have to tell the customer to leave the car there all day?
Great example! Yes, there is no other way to cool down the transmission fluid. Thanks for your feedback
Can you check the fluid temperature with theromter for cooking through the plug access hole
Super professional and deep deep detail!
Have you tried filling it through the driverside plug on toward the rear of the transmission
I love the professionalism
I can’t believe it heats up just idling. I have a ZL1 1LE and getting over 203° seems crazy.
This is a great video and is very well done. I've seen so many people do this wrong. Please make more vids like this. Thanks.
Thank you!
What a great video! Clear, very easy to understand, and perfect for the job. My Colorado and I thank you!
Great and clear video explanation. I've done exactly as explained here to my chevy trailblazer with 6L50 transmission. Fortunately, I can reach the side filling hole and extend it with hose to fill in the fluid. I flushed the whole fluid using internal pump as well.
Idk if it makes a difference but on my Colorado the transmission sits lower in the back than the front. And idk if they want the truck level or the transmission level when I check the fluid.
Yes, Level truck
Wouldn't the transmission cooler stop the torque convert from over heating? Its my understanding that fluid from the converter goes straight to the heat exchanger then it is returned to the pan to repeat the process. A pickup truck with a max towing load can stay in stall for minutes at a time in normal driving conditions. How would a power braking do damage any significate damage?
With few exceptions, the cooler flow rate is less than is needed to keep up with the heat generation at full stall speed. Many pickup trucks have a Tow/Haul button on the shift lever. In the Tow/haul mode several strategies are used to prevent overheating the torque converter. Typically the Tow/Haul mode prevents towing in the overdrive gear ranges. That makes it harder to reach full stall speed while driving. The transmission control module also have two modes of heat reduction. 1. The "Hot Mode" engages the torque converter clutch to stop any heat generation inside the torque converter. This mode continues until the fluid temperature drops to an acceptable level. 2. "Super Hot Mode" signals the driver to stop the vehicle and idle the engine to allow the transmission fluid to circulate through the cooler until an acceptable temperature is reached. Stopped or while driving; taking the torque converter to its maximum stall speed can bring the fluid temperature above 300 degrees F and ruin the fluid. once the fluid reaches 500 degrees F, the steel housing of the torque converter will start to turn blue. Remember that the fluid temperature can rise 10 degrees F per second at full stall speed. it would only take 30 to 60 seconds to reach a damaging temperature. Transmission coolers extend that time period, but excessive operation at full stall speed will ruin your transmission.
Hi I have 2020 1500 Sierra with 10 speed do you have a video on the transmission fluid service
Can you explain or show the Trans Cleaning Procedure that flushes clutch solinoids and pressure regulators using GM software or other tuning /scanner software such as HP tuners
Thank you for your feedback!
Let you know that GM is currently shipping (free of cost) a bosch Trans cleaning system and 55 gallon drums of Mobile 1 LV ATF HP to every dealership. They will have the tool kits probably by Feb end. I think allot of the problem with prior repairs was improper cleaning. But there is a new update from this month to all dealerships. I actually have a copy of it and its happening. Hopefully will finally resolve the shuddering 8 speed problems. This may be different from what your talking about but its relevant to fixing the issues with the 8 speed.
I have a Cadillac cts vsport with the 8speed Asian transmission I had the dealership drop the pan and replace the filter and refill twice now in 8th gear when at operating temperature I get hesitation. Does that sound like they didn’t fill it correctly? It’s definitely not spark plugs or coils
The detailed explanation is very very very good.
Thanks for watching
How do I know if it is overfilled? I had the trans temp sensor replaced and a service done. A week later my trans doesn’t want to shift. RPMS shoot up and shifts hard.
How does this work after a torque converter is replaced ? How would it work being that low of fluid while getting up to temp w/o damaging anything
"Brake torquing"... The converter is a fluid coupling device.
In operation, climbing a hill in sf that takes you 3+ minutes creates significant equivalent brake torquing. Driving the windy mountain pass through berryessa where speeds are low enough that the tcc stays unlocked, performs the same "brake torquing" action. Being in gear, while stopped, is brake torquing. Different levels of loading, but all do the same thing. This is the reason converters arent air cooled anymore. Also why a lot of performance cars come with external coolers as well. I dont see any reason that "brake torquing" to heat the trans fluid would be a problem so long as you were monitoring the temp with a scantool.
Good point, but everything has limits. The difference is brake torquing takes the engine rpm to the stall speed of the torque converter and keeps it there (10 degrees F rise per second). Driving on roads and conditions as you have described may not always keep the engine at maximum stall speed. If it did, it would cause the same damage as brake torquing. Every vehicle has a maximum towing capacity and hauling capacity. If you exceed that capacity, expect an overheated transmission. A scan tool typically shows the sump (pan) fluid temperature, not the temperature of the fluid leaving the torque converter (through the oil pump) and heading to the transmission cooler. When the transmission fluid reaches a temperature above the normal 220F - 250F range, some of the blended fluid additives in ATF can begin to evaporate. This effectively kills the transmission fluid and eventually the transmission. Thanks for your feedback.
@@WeberAuto yes, i agree. However i dont think anyone expects a full blown pedal to the metal, full stall brake stand to warm the trans. Lol.
Unfortunately I have seen it happen too many times. Keep in mind that most stock torque converters have a stall speed between 1800 and 2400 RPM. Going to wide open throttle is not necessary to reach stall speed. A light throttle to 2500 rom would do it. Thanks again for your feedback. Have a great day!
So how exactly am I supposed to check fluid level on my 10speed when the temperature does not go over 200 unless I'm driving it hard?
I agree. It takes me 30 minutes on the track to get to 200 degrees
Stop and go city driving should have it there after 15-20 minutes of driving. High speed driving will lock the converter clutch and stop heat generation. Thanks for watching
2013 Camaro v6 automatic the trans started slipping pretty bad at stop signs yesterday. Today it won’t even drive so I’m guessing somehow my fluid has leaked out? I’m going to try to add some today.
My 2013 ss has had a steady stream for over 5 min... started fast, slowed to a very thin drizzle(not a drip)... did a pain drop filter and fluid change... can not get it to just drip
Amazing video. I have a 2015 V6 camaro and now I feel confidence to do it by myself. Thank you.
Was that transmission overfilled for the purpose of the video? Or can we assume that transmissions are overfilled from the factory?
Great question. It has never been touched. It was slightly overfilled at the factory. The fluid that came out equaled about 0.355L or 12 fluid ounces (0.375 quart). The drain hole is so small that it appeared to drain more than it actually did.
Just 12 oz ? that pan you were holding with the overfilled fluid looked like a lot more
WeberAuto quick question ive just turned 18 and i am looking at a pontiac G8 with the 6L80e. It has 132xxx miles. I read on forums these trans arent all that reliable. So now i must ask you what your opinion is on these G8 trans. Thanks -Flow
Quick question?
1)How much transmission fluid comes out when you drain the old on?
2 )how much new fluid do you add in ?
Where did you get the temperature range for the fluid level check? I've been trough the forums and the temperature is different as the one you said
"The transmission fluid level must be
checked when the transmission fluid temperature
(TFT) is between 35-45°C (95-113°F)."
static.nhtsa.gov/odi/tsbs/2019/MC-10163890-9999.pdf
I did according to your video but now i'm in doubt if thats the correct temperature to check the level.
Great video! Question: I have a 2019 Silverado - 8L90 with 38k miles and about to have the trans fluid maintenance done. Called a couple Chevy dealerships: 1) 1st one, they would drop the pan, change the filter & gasket then refill, 2) another dealership suggests only doing a drain and fill with no new filter & gasket and finally, 3) last dealership recommends a flush (not drain and fill) with no new filter & gasket. I am sooo confused as to what to do. I have heard to NOT do flushes these days. Thoughts Please and recommendations.
Does anybody know where to find the adapter for the fluid level check plug to fill the pan with new fluid ? Greatly appreciated
Question: I have what's believe to be the 6L90 but have torque shutter, can the mobile 1 synthetic LV ATF HP be used or best to still use the Decron-VI recommended for the 6 speed?
Keep licensed Dexron-VI in the 6L90, no HP, no universal fluids.
best video ever saw
how many litres for transmission oil change for the 10 speed automatic SS. thanks
Awesome video. Have been looking for this procedure for months. Thanks.
Thank you! I am glad it was helpful
I have to check the transmission fluid on my 16' Cadillac CTS-V3.....would you happen to know which fluid it takes?
Great video
I do have an honest question that I hope someone could answer in regards to a 2013 Camaro ZL1 with the 6L90 transmission .
AC Delco makes both a conventional and fully synthetic version of Dexron VI. Is there any disadvantage in using the synthetic version of dexron VI in the 6L90 transmission. I have had numerous people tell me just use the conventional Dexron VI and do not use the synthetic version but nit a verified reason as to why? Even when searching if this item will work in my vehicle most places show NOT Compatible?? Have there been issues putting the the synthetic version of the Dexron VI in the 6L90. My transmission only has 45K so if its because of the thinking of it could cause slipping if the clutch packs are worn then maybe but it seems to be OK.
Just looking for a honest and educated and technical answer as to why i should not use the sythetic version of the Dexron VI since its made by Ac Delco.
Would like only professional people to advise.
Thanks for an info you can give
All GM Licensed Dexron VI is the same, there is not a conventional version and a synthetic version. GM Licensed Dexron VI has always been made from "Synthetic" base stock oil (which can be a group 4 PAO or a Group 3+). Licensed fluids will have a license number on the that begins with the letter "J". There is a lot of aftermarket, non-licensed fluids out there claiming to be compatible, meet or exceed standards, etc, but I would not use anything but the original licensed factory recommended fluid in that car. I made a video on the problem of misleading labels and claims on automatic transmission fluids, even from ACDelco. See ua-cam.com/video/xUFY0L_zFek/v-deo.html
My 2018 Escalade has torque converter shudder. It has 10 speed auto can I change the fluid to the Mobil 1 LV HP ?
Hey great video. 1 question about the 8spd transmissions. there was mention of changing oil to the specific Mobil 1 oil if there was an issue with torque converter shutter. Would you suggest it may be a good idea to preemptively switch to that special Mobil oil as a preventative action so you don't get the toque converter shutter in the first place? Also do you know why they suggested this a a fix? like whats the difference between the oils anyways ?
If it were my vehicle I would switch to the newer fluid. Both fluids are comprised of a fully synthetic PAO base oil, but the Mobil fluid has a different additive package to reduce torque converter clutch shudder.
@@WeberAuto I currently have a Colorado in production as I type this. Asked my sales manager if they are using this mobile 1 in new builds. Said nope. Only those with shudder. GM sending out 55 gallon drums to all dealers along with new Bosch tool kit to flush/decontaminate transmission. But told me my new truck will still have old fluid. I will press them to put the new fluid. The best time is when the truck is new. Does this stuff cost allot more? Why is GM not using this on new production?
@@HiPlains1 We bought a case of 6 for $68 USD.
@@WeberAuto GM refuses to use on truck that is currently in production. Dealer will not apply it until there is a problem. And the dealer told me that 20 percent are having the issue at some point. I'm hoping GM will refund my deposit under the circumstances. But I can't accept this order and will not accept the truck any longer. I am also not willing to pay 500 dollars on a brand new truck to have the fluids replaced. This whole experience has not been good and GM should have started to use this back when you put this video out. 18 months ago. Wow. No, they would rather customers, one by one, experience the shudder, damage the Torque convertor, then have to bring into service etc... and go through all that then to just put the fluid into new production. I can't and won't support a company that acts like this. Not even remotely so.
Update. I'm hearing GM is finally starting to use the new fluid in new production. Early reports say its having good results in fixing the problem. So if you buy a new Colorado just make sure it has a build date on March 2019 or after. Avoid all models before that. Because the dealers won't do the fluid flush unless you can PROVE its having the issue. And that is not always easy thing to do. So best just avoid it if you can. Also my two cents is just buy a Frontier Pro 4X. The VQ40 24 valve DOHC with 5 speed OD is still the best motor/trans tune by far. And the ergonomics are better then the GM. Better seats, more comfortable and 8 way power. Also has sunroof, real locker, 31 inch all terrain with dual climate control etc... loaded. And it will cost 5 thousand less then the GM and will be rolling around for years after the GM truck is rusting out in the junk yard. Just not worth the trouble. GM has been struggling for years with their mid size.
@@HiPlains1 cause GM already has your money. they no longer care about you.
What adapter would you recommend to fill the transmission easily
Good question. It is a straight thread, not a pipe thread. I do not recall the size. Probably 10 mm
The biography link in the video description doesnt work!
Thank you, I fixed it www.weber.edu/automotive/J_Kelly.html
Nice! I just have a thing to be cleared - which much be leveled during the check: the vehicle's chassis or the ATF pan? Thank you!
good evening , very well spoken representation and broad approach for more than one application all in one video. thank you very much for your time and informational video. the gentleman of tech
Thank you for the instructional video Sir.
My question is, what computer and or equipment did you use to monitor the transmission fluid temperature ? Any help would be soo appreciated Sir.
Modus. Snapon versus
Any quality scan tool with support for the year and model you are working on will work. A "code reader" will not work.
That side fill plug is a bear to get to, but not very difficult as described. The heat shield bolts covering it is difficult to get to. The 2nd time, I was able to reach over the heat shield, down to the plug with ease. I would never remove the heat shield the 2nd time, but the first time it is near critical.
could you please explain why when the transmission system when get over than 80,000 KM on my 2012 chevy cruze we can't change the oil because there is a chance for damage it
Hi, The recommended service interval for your transmission is every 156,000 km. Changing the fluid before that will not hurt anything as long as the person changing the fluid does it properly at the correct fluid temperature and with the correct fluid. Best wishes.
Thank you I really appreciate , god bless you
Thank you for explaining clearly. Great picture quality
Where did you find the temp ranges? Everything else I see on line says 93-113 degreed. You are the only one saying 131-149???
Sir... ive a question. when you compare this pan to the Toyota pan you had on
("Toyota Transaxle Fluid Level Check - No Dipstick" on Apr 14, 2015). which one is shallower?
looking at height of the leveling standpipe, the normal fluid level would be "higher" than the depth of this pan.
if that is the case, i would think it will leak over time when cold. esp after a pan removal.
This pan is more shallow. Pan depth does not tell the full story, you must consider length and width for overall volume and stand pipe height calculations.
True... Thanks :)
Hey john, do you know if the temps are the same with 4wd trucks. I bought a 2019 Silverado with 5.3l 8L90 4x4. I wanted to know this info before 30k.
