Transmission Fluid & Filter change 2021 - 2024 GMC Yukon XL Denali LM2 Duramax

[@MolotovGarage]

There will be new video posted soon as I am about to do a 90,000 transmission fluid change. It will be more detailed and more in depth as I will be more through this time in terms of explaining steps on video. Especially when filing up the fluid and bringing it up to temperatures.

[@danbell6380]

How much fluid came out when you first removed the fill plug? I plan on doing a drain and fill and want to make sure I capture that, thanks.

[@MolotovGarage]

@@danbell6380 I didn’t measure fluid that came out. I was more concerned on filling it properly which is you have to fill it up, plug it, warm transmission up to temps and open plug and check the level by letting excess out.

Could you show a still picture of the torque sequence? Thanks!!

[@MolotovGarage]

@@davidgertz07 thank you I will find it a post a link here

[@jeffw3382]

Where did you find the picture diagram from a different KZbin video

[@MolotovGarage]

@@jeffw3382 I’ll post it in the description thank you for reminding me.

[@MADDOG100ful]

Use the electric ratchet,,, off and on..until getting to the torque down part.

Isn’t getting 8 quarts out of 10 with only draining and filter change considered a high ratio, how did you manage to get all of that old fluid?

[@MolotovGarage]

@@khalidalghamdi2512 just do more frequent intervals. I did first one at 50k next one at 40k and next one coming up at 30k. Makes a huge difference in transmission performance, don’t over analyze until paralyze just do it. 90% fresh fluid is better than 100% old fluid

[@2ss701]

How did it shift compared to the ACdelco ULV fluid?

[@MolotovGarage]

@@2ss701 it just feels smoother, and less “kinks and kicks”

[@victorrodriguez8917]

I believe you did remove the exhaust right ??

[@MolotovGarage]

@@victorrodriguez8917 this is a 2WD model so there is thankfully no exhaust pipe or any drive shaft on the way. It’s a good mention I will mention that on next transmission fluid change.

[@JoseSanchez-vk7fh]

I don’t know why the dealer charge 1800$ for this ! Thanks very much 🙏🏻

[@pablomata6347]

Because actual techs that buy expensive tools have to be paid by the dealership

[@Anthonythesider]

What about the rest of the old fluid

[@MolotovGarage]

@@Anthonythesider it came out when i dropped the pan, just weird angle didn’t show it.

[@Anthonythesider]

@@MolotovGarage there is still more old fluid in the transmission that you didn’t get out

[@MolotovGarage]

@@Anthonythesider it’s already 14,000 miles from another transmission fluid change at 90,000

[@danbell6380]

How did it shift with amsoil ?

[@MolotovGarage]

@@danbell6380 I don’t have that thump when it shifts around low gears anymore specific on steep uphills. It’s just smooth now like on my Mercedes

[@2ss701]

How many quarts did you use?

[@MolotovGarage]

@@2ss701 I filled up with 8.1 quarts. However also when you are at the step where you have to bring transmission to temperature to level the fluid, once you open the fill plug fluid will come out until drip, then close.

[@2ss701]

@@MolotovGarage I think this is different on the 10 speed Camaros I saw 6.5 quarts. But the pan on the Yukon I think it’s bigger.

[@AlisoBob]

When you swap the filter.... the bolts take 44 in/lbs PLUS 128 degrees of rotation. You left that part out.

[@user-wo6ow5pn5u]

Does anyone have this in a procedure. IF you rotate another 128° it seems like you will increase the torque dramatically

[@MolotovGarage]

I just stick to 44 in lbs, once torque wrench buzzes its enough for me. These bolts impossible to find I dont want to risk stripping them or inside the tranny

[@MolotovGarage]

I just see the 44 inch lb unless @AlisoBob gives us a screenshot of dealer step by step sheet for the tech

[@AlisoBob]

Whats a good email to send it to?

[@MolotovGarage]

@@AlisoBob [e-mail] thank you bro 😎

[@victorrodriguez8917]

Ohhh i c ., you have the diesel engine ., thats why you dont have the exhaust across the bottom of the pan .

[@radiohead2206]

This is too easy. I have a 4X4 Suburban, and the muffler is a bitch to move. Not a home project. Need a hoist and two guys minimum.
