Dude, what an awesome video. Short, full of perfect information. Literally this is what every how to video should strive to be! Nicely done! Also thank you!
Thanks, no nonsense, but detailed, can’t ask for more than that! The dealer just quoted me $125 for servicing just the transfer case, I had them do the trans, service for $635, but I typically do the other services myself. After choking on the $125 for a quart and a half of fluid I thought I’d look up a video making sure it’s an easy as I figured.
Good video. My question is if AC Delco also makes transfer case fluid, how do we know to use the ATF instead? Didn't they make fluid specifically for the transfer case?
So I keep getting mixed info on the mobil 1 lv atf hp fluid saying it's compatible with dex vi. The older black label says it is however I ordered 2 quarts and got the blue lable which doesn't mention it on the back. Would this also work and be compatible. In my t case 2020 silverado.
Yes, blue label is the newer, improved formulation over the old black label. This is what most recommend using to prevent or fix trans shudder & rough shifts when doing ATF flush & fill on our trucks. Dealers in the US use ACDelco Blue Label. Most DIYers seem to go w/ the Mobil 1 for xfer case & trans tho, and Valvoline 75w-90 synthetic gear oil for both differentials. This is what I'm using after a decent amt of research. I have the 8-Spd 8L90 trans btw.
Thanks for the reply, I grabbed some mobil 1, I'll look to grab valvoline for the diff, I still find it odd there are 2 different gm part numbers for the diff fluids. I've seen others using ams oil. What's your take on the ams oil
I considered using Amsoil. It's good stuff, but pricey. I don't really tow w/ my truck right now, which puts way more stress on the drive train, and I'm not putting crazy miles on it (~15K miles/year). If I start beating on the truck more, I'd prob give the Amsoil a try. 🤙
@@MasterJacksquestion my Manuel says 75w-90 for the transfer case and that the 1500 series rear diff’s take 75-85. Would one be fine using the 75w-90 in that unit? A pretty good auto parts store is saying their system says it’s fine to use it in the rear. The 2500/3500 calls for 75-90. That 5 gonna make a difference? I assume fresh oil is better than old. Front differential rather sorry. Not transfer case 😂🎉 front diff. 😮
If you have a 10speed transmission, you have to use the special fluid. You fill it until it starts running out the fill hole. Run it up to 186F (check your dash fir trans temp) then open tje fill plug and and let it drain until it is barely seeping out and close it up. That is the procedure for the trucks. They also call for replacing the 2 bolts that hold the filter in place....like $16-$20 for those.
@@MasterJacks Thanks, I missed that in my viewing. I guess that I was just focussing on where the fill plug was and what tool it took; and missed the annotation. Thanks for the video. It is nice to know ahead of time that it is as simple as I hoped it would be.
Interesting, thanks for sharing. I'm showing 1.6qts for the transfer case on 1500, 2500, and 3500. This one would have been grossly overfilled with almost another full quart.
Holy shit a no-frills service video. Instant subscribe.
AGREED
Yep
Probably one of the best how-to videos I’ve seen on here. Thank you for making this
I totally agree exactly to the point telling you everything you need and didn’t drag anything out. 👍🏻

Fantastic! Thank you for short and to the point video.
Great video. Answered a question. My owners manual said see dealer when I was trying to find correct transfer case fluid in owners manual.
Wow nice video ! 👍🏼
Great video, thank you
Great video
How about a video on changing rear diff on the new 2022 rear diff of a Tahoe/Yukon? I can’t find a video it anywhere. Thx

2019 silverado 8L90 transmission...im changing the fluid to mobile 1 synthetic, do i use the same for the transfer case?
What oil do you recommend to be used for the 2019 Silverado 4x4 ?

A shop quoted me $800 for this service
Surprised it does use gear lube
why not just use high temp white thread sealant like with the 2011 silverado tc vid?
I'm sure that would work just fine 👍

@@JFEnterprize I wouldn't hesitate to use 75W90 in the front or rear diff.
I have a 2023 suburban with 47k miles, iam gonna change the transmission oil not flush, how many quarts fo I need ?

Probably a dumb question, you use transmission fluid for the transfer case? Same fluids?
The transfer case uses Dex VI ATF, however, the 10-speed transmission calls for Dex ULV ATF (ultra-low viscosity).
Surprised it doesn't use gear lube

What mileage is the transfer case service due at.? Thank you.
The owners manual states every 45k miles
@@MasterJacks Thank you. I appreciate the feedback.
Do I use that same oil with a 2021 gmc sierra 4x4 sle??
Yes, same fluid and capacity.
Mentioning socket and allen size in video would be helpful but otherwise nice video.
👍 You can find them displayed in the upper left corner of the video during the shield and plug removal.
17 mm
Wrong info....its 2.4 quarts per gm tech service manual.

I believe that's for the diff.
It’s fill to the fill plug or slightly under. If it took 1.6 then it’s 1.6
you forgot to mention the HEX size of the plugs, what's that? 10mm?
@acheronlv-4268 Thanks for watching. It's displayed in the upper left corner as text. 8mm.
if it was 10mm, you'd have to go buy a new one for the one that escaped🤪 while your weren't looking
@@Gary_Le_Strange so, i went to autozone and bought a set for 25 bucks. not sure what size was but it worked
