How to change the transfer case fluid on an Escalade, Denali, Yukon, Tahoe, Silverado.

Transfer case fluid change is suggested at the 100,000 mile mark for most GM engines. I go ahead and change the fluid on my 2008 Cadillac Escalade. Same procedure for the Yukon, Denali, Silverado, Tahoe, Escalade, Suburban.

Omar I appreciate the great videos man! I have an 04 yukon denali and you've helped me out. For all you guys in the rust belt like me, always make sure your top fill bolt is removed first, if it's stripped you have no way to refill until that's dealt with.

[@OmarsGarage]

Will Wild glad I could help and thanks for the tip. You should always remove the fill plug first. Mine looked very clean and my car has been garage kept so I took the chance, but you should always remove the fill plug first. 👍

[@doubleya215]

@@OmarsGarage I can see how clean she is underneath! Must be nice man... up here in NY- not so much.

[@28704joe]

FYI, I just saw a video where you can fill thru the speed sensor up on top of the transfer case for anyone who needs to overfill for potential leaking issues.

[@tarquineous]

@@28704joe Better to fix the leak instead of dripping fluid over the streets.

[@kvasir40]

Thank you so much for uploading this step-by-step video. I was able, following your precise instructions, to perform this transfer case fluid change (2014 GMC Yukon). Most appreciated.

[@Everythingoutdoors902]

Shoulda made sure the fill plug came out before draining the fluid somtimes they dont. good vid tho!

[@OmarsGarage]

You are correct. Thanks for the tip.

[@DustinSilva]

What's interesting is my 2007 Escalade EXT (with the Borg-Warner transfer case) calls for Manual Transmission / Transfer Case Oil right in the Owners Manual; and confirmed by two different Dealerships. My truck is AWD though.

[@ralphfactor579]

Loosen fill plug 1st Don't apologize for using store name oils & fluids they meet the same standards as big dollar brand names

[@TheOriginalFrankMatthews]

Great job!

[@garyt534]

Loosen the fill plug first, before draining the fluid. After draining is a bad time to discover a seized fill plug. you won't be able to properly refill the case through the drain plug.

[@sirsweetness8332]

Did this transfer case fail? Dexron III is only fluid to use in this if it is a manual transfer case. Dexron VI is not reverse compatible

[@OmarsGarage]

Dexron VI is backwards compatible with Dexron III. You can not put put Dexron III in a newer vehicle that requires Dexon VI. I called the dealership to make sure before I did this job. You can also see it in the description here www.acdelco.com/parts/oils-fluids/gm-oe-dexron-vi-transmission-fluid

[@christophersarbu9161]

amazing video thanks. do Inalso have to change a fluid in any differential?

[@OmarsGarage]

I never changed it out as it was not in any of the maintenance schedule, but many people recommend changing it out every 50k miles. Towards the end of this video he changes out the differential fluid kzbin.info/www/bejne/bHithIawocx0o7c

[@3rdiknowledgetv]

Hey how do you know when the transfer case needs fluid or repaired

[@OmarsGarage]

If you are hearing a grinding or noise from the transfer case or if you see leaks during an inspection.

[@scootersmith7362]

Awesome video..thanks

[@OmarsGarage]

Thanks 👍

[@dtabor8873]

If that is awd you used the wrong fluid.. that gm awd needs autotrak 2 not dex 6.. its a blue fluid made special for that type of transfer case its basically a more slippery fluid to prevent premature ware on the clutches

[@OmarsGarage]

I got that from my manual, and I also looked it up in the GM repair manual. Called for Dex III. I called the dealer and they told me Dex VI was an updated version of Dex III and was backwards compatible. Here is the text from the repair manual “Directions The following actions occur because of the planetary differential: •If the vehicle is on a hoist, the front propeller shaft can be rotated by hand. •cThe vehicle cannot be driven if one propeller shaft is removed. •Operating the vehicle on the hoist can damage the differential pinion gears, by over-spinning. •Operating the vehicle with one propeller shaft removed causes over-spinning of the differential pinion gears. The BW 4481 design of the planetary differential allows the use with the Vehicle Stability Enhancement System (VSES) vehicles. The VSES takes use of the planetary differential, by applying braking to a tire that has less traction and dividing the engine torque to the other axle. The BW 4481 case halves are high-pressure, die-cast magnesium. Ball bearings support the input shaft, the front output shaft, and the rear output shaft. The transfer case requires DEXRON®III ATF GM P/N 12378470 (Canadian P/N 10952622), which is red in color. “

Does your truck have any drive line clunk. I have a yukon and have a bad clunk. I put the nickle plated slip yoke still does it. I hear they all clunk

[@OmarsGarage]

It’s been over a year since I traded the Escalade for a Tesla Model X, but I don’t really remember any unusual clunk. The truck shifted smoothly as long as I owned it and I had over 100,000 miles on it and owned it for about 11 years as the original owner. Hope you get it resolved...please update us if you figure it out. Thanks 🙏

Yup it’s AWD. They do make a 2WD version though. The AWD can not be placed in 2WD mode so it’s full-time AWD.

Get yourself a 1gal garden sprayer from wm $5.88 Take the tip off the sprayer and carefully heat the last inch of the tube and bend it close to 90deg, now you can do trans flushes and fill xfer cases easily Keep a 2nd one for diff oil I just saved a bunch of you guys a lot of headache for under $20

They were probably just referring to the fact that you have to buy two quarts as in two bottles. There’s physically no way to add a full two quarts though.

Question does the second gear on these trucks come in quick?? or I might got a issue..

I sold the Escalade for the Tesla about a year ago, but I remember it going through the gears pretty smoothly. I think I had over 100,000 miles on it when I sold it and never had issues with the transmission.

[@willisthompson6]

Usually it comes in quick when a solenoid is bad in a transmission.... changing the fluid sometimes help or you have to kind of release the gas pedal a little right before it hitting seconds gear for a smooth shift

Is the transfer case oil the same as the transmission fluid ? Is this basically changing the transmission oil ?? I have 2002 Tahoe and the slip Yoke has been leaking.. so is that transmission oil leaking or transfer case oil ?

ATF for both, different reservoirs.

[@28704joe]

Is your vehicle AWD? All wheel drive transfer case require special fluid ACDelco 88861800 not ATF Dexron VI. ( Per my 2007 Denali manual)

[@OmarsGarage]

I recommend you use whatever your manual says. It was an AWD vehicle. I had researched this at the time and talks to someone at a Cadillac dealership that said Dexron VI was better. The manual called for Dexron III I believe.

[@28704joe]

@@OmarsGarage Interesting, thanks for response I'll investigate too. The term "transfer case" in manual seems too generic given difference between 4WD and AWD . Manual does not specifically indicate my car is a AWD, just says "transfer case" and 88861800 is identified as "manual transmission oil" . Nice job on video. I'm inclined to use ATF as you did.

Why are you putting locktight on the fill plug?

[@OmarsGarage]

It’s not lock tight, it’s thread sealant. It’s just a safety measure with a high temperature sealant. Description from the manufacturer “ Heavy Duty Suggested Applications: Differential drain plugs and core plugs. Pipe, water jacket, oil gallery plugs, oil pressure & temperature sensors, air conditioning fittings, hydraulic fittings, vacuum line connectiors, air brake fitting”. Not 100% necessary, but doesn’t hurt.

[@clintbill5098]

@@OmarsGarage can you tell me the brand I should buy for thread sealant. Should I use it only on the plugs of front diff, rear diff and transfer case. Plan on changing trans fluid next week on my 2018 Cadillac Escalade.

I attempted to check mine today and pulled the fill plug obviously the one at the upper position but it started gushing out I’m not familiar with these I’ve been working on cars since I was 10 learning from my step father but I never really got into doing drivetrain stuff on trucks

[@OmarsGarage]

First question is probably silly but was the truck level? I would check the transmission fluid level just in case it’s leaking into the transfer case.

@@OmarsGarage other videos say trans leaks INTO transfer case if seal is bad. It would be smart to check FILL plug FIRST and verify no EXCESS fluid is spilling out, then remove drain plug and drain
