Camaro, Corvette, Cadillac 6, 8, and 10 Speed Auto Trans Fluid Level Check - No Dipstick

[@warddc]

Here 6 years later watching this video. Very well done. Thank you.

[@chadpugh1490]

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.

[@orlandot3944]

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.

[@WeberAuto]

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?

[@bsh724]

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!

Dude, you rock! Please don’t stop doing what you’re doing. EXCELLENT explanation!

[@jamesfarnham1976]

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.

[@WeberAuto]

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’ve learned more from this video than the 6 months I’ve spent as a lube tech at a dealership. Thank you.

[@roadracing3]

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!

[@giogarcia3777]

[@ishunu]

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

[@FerasDishli]

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

[@floydhelms44]

You are highly knowledgeable and well fluent in explaining this type of transmission. Surpurb!!!

[@Dentonboy]

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!

[@banghambgrch]

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 .

[@bryce6870]

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!

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!!

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.

[@WeberAuto]

LOL, yes, thank you

[@HiPlains1]

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.

[@hashtagjustadad5110]

Very detailed explanation. This explains a lot about why the manual says to take it to a dealer.

[@cardo1111]

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.

What a great video! Clear, very easy to understand, and perfect for the job. My Colorado and I thank you!

[@splatmatt]

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.

[@mattmccauley1110]

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!

[@goddesseddog]

Really great engineering w/ confusing, different temperature requirements; not even a drain hole. Seems engineered to make money in the service department.

[@WeberAuto]

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!

[@KSSilenceAU]

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.

[@beyerch]

@@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.

[@michaeldose2041]

@@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.

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.

I thought the fluid check procedure on the M75 VTi that was in my Saturns was a pain (I say was because they’ve been swapped out for the AF23). Good thing the 2021 SS and it’s 10 speed will be going to the Chevy dealer When it needs a trans service. Excellent video once again.
