    Cadillac ATS Transmission Service Day!

    Following upon this. I checked the torque on the pan bolts again on my last visit using the pattern posted previously and they were all perfectly still set at 80 inch pounds. No leaks, perfect seal with that stock double dimple gasket from GM.

    Great thread. Lots of options. Noticed A30M and TopDon are pretty close in features, while the TopDon is half the price. Ordered both and tested the Xtool last night... works really well and the amount of updates it downloaded on first boot was impressive. Going to test them on the ATS's and...

    Valvoline R&P Oil Burner Test Results

    For the record, the most boutique oils available are ACDelco, in a cute boutique shop with sweaters and hats and stickers, with insane boutique prices that make Amsoil and HPL look like clearance products! But I do use their gear and transfer case oil... held up for 11+ years in the ATS tiny...

    Valvoline R&P Oil Burner Test Results

    HHS2000 viscous seepage, turns to grease, no fling, takes 5 seconds to apply with a centre stand. Used it for years on pretty much everything. Not cheap, but you need so little to make a difference on things that need it.

    Cadillac ATS Transmission Service Day!

    The final step to a full fluid swap is clearing the TCM Adaptives, especially when the previous fluid is 10+ years old and came out like a hot chocolate turd. Followed by a nice backcountry rip. Car is shifting beautifully, really grabs on aggressive shifts (did not feel like that before... very...

    Cadillac ATS Transmission Service Day!

    As a follow up to this, I was done the pan drop and first fluid replacement in an hour. Another 30 minutes for the second extract/dispense. I suspect this could all be done in 1.5 - 2 hours. I'll test that with the 2017 ATS coming up.

    Cadillac ATS Transmission Service Day!

    And just in case I have this sitting on the shelf, made with tougher roller bearings, 3rd gen seals and I’ve installed a modified low pressure vent. Has a little 80w90 rolling around while it waits on the bench for action 🤙🏻

    Cadillac ATS Transmission Service Day!

    Some of ya might be familiar with the rear differential issues in these cars. Root cause has two vectors. 1. First and second generation seals were, well, sometimes leaky. Low fluid = failed delicate ball bearings. 2. Some diff vents had unreasonable spring pressure causing them not to vent...

    Are we over exaggerating the perfect ATF fluid level? thermal expansion seems to think we are

    I think OP is bang on if we’re talking a small spread of temps like 10-15 degrees. But it is interesting that even GM’s procedure allows for an almost 40 degree range.

    Are we over exaggerating the perfect ATF fluid level? thermal expansion seems to think we are

    Just did check level after three dump and fills and this is what I did on the 2014 ATS 6 speed. YMMV. 1. Brought a big fan to the lift 2. Opened the hood and put the fan under the car to push the heat out. 3. While it was cooling down I performed the final dump and fill. 4. I pumped new Dexron...

    Why are Chryslers said to be sensitive to whether you use +4 or not?

    Case closed. I plan on doing the trans service on the Dodge van soon and ATF+4 is going in. Thanks @MolaKule

    Due to the fan, I started the car up at 104 degrees. I believe the fan is critical for temps to get in range. I would likely have been over range otherwise.

    Cadillac ATS Transmission Service Day!

    Thanks for the tip! Made a huge difference AND made for much cooler and breezy work under the car. Comes with me every time now and the garage guys were laughing and all converging under my car to cool off 😂

    post your latest transmission lubricant change.

    About 20 quarts of ST Dexron VI through the 2014 ATS 6 speed, new filter, and all driveline fluids replaced last week. Textbook execution, shifts like new 🤙🏻

    Cadillac ATS Transmission Service Day!

    Ahh yeah…. money shot 🤙🏻 THAT’S HOW you do the check fluid procedure 😎 Brought a big fan with me to the garage. Made a huge difference. Started the car at 104. Climbed to 113 by the time I put the plug in.

    Cadillac ATS Transmission Service Day!

    With a bit of rain and cooler temps I arrived at the lift almost 30 degrees cooler on the trans! Also arrived early to let the car cool. Brought a big fan to put under the car if needed when on the lift to get temps down faster.

    Yep, good kid. Good eye opener for him cause he asked the dealer and he figured the car was done for.

    You'd have to be pretty determined to make a case with me lol. I'm the type of person that would just say "well, it is what it is, take care".
