Good advice MolaKule. I changed my 2003 Sierra 4x4 Xfer Case Fluid 3 times now in 200,000 miles (on it's 4th fill).

Zero problems and I'm not easy on the drivetrain......

To play devil's advocate and to add to the conversation...

With this opinion shouldn't we all stick with OEM atf in our automatic transmissions too? Especially since it's even less often that it needs to be changed out? Lots of people, including myself, use multi-vehicle ATF's like Maxlife ATF and RP MaxATF in our transmissions with no hesitation and no issues. It's my understanding that an automatic transmission is a lot more complicated of a beast than an automatic or manual transfer case.


I see your point but don't think one can necessarily draw that kind of conclusion.

This TC has need of specific friction modification. Now Valvoline may well have developed a TC fluid with a spread of friction coefficients that may work well in the three units they claim they cover.

For AT's there are only about 3 or 4 clutch material manufacturers. Many of these materials are similar.

The main differences are found in the programming (timing) of gear changes with engine speed and torque, and clutch/band pressures.

In terms of MaxLife ATF, I think they have done a good job of finding workable dynamic friction coefficients that cover most of the clutch materials, timing, and pressures used.

Yeah, the fluid has been replaced... along with the rest of the transfer case.

Why would the OP care what a completely different transfer case uses for fluid?

I'm not sure what transfer case he has. In 2010 auto trak was used. 2012 it's dexron vi. Same t case as far I know. My 2010 isn't automatic which just uses dexron vi. I bought auto trak fluid for the 2012, then read the owners manual...... Dexron Vi.

I was hoping this would work in my Borg Warner BW44-44 transfer case on my Ram but Valvoline said they don't have a fluid that crosses for the Borg Warner transfer case.

I see O'Reilly carries it.

Compared to which other transfer case fluids?

Compared to Dex/Merc/ATF+4...

I was eyeing it for a couple transfer cases but will go thicker.


At what point should a lurker start posting :-)

I reckon it's kinda like Dex6 / Merc LV / Maxlife ATF - because they don't shear down like DexIII/Merc

Are you experiencing the shudder when turning tight? If so you need to change the fluid, run it for a while, then change again (gm recommended procedure). At $9 a bottle and 2 bottles flush it's not inexpensive.

That said, it's a questionable call, and this isn't a cheap 203 transfer case either. Personally I would just use the GM stuff, it's proven to work and work well, and in reality there is little to be gained here other than possibly a few bucks.

I found the OEM fluid at Napa, slightly cheaper than the Valvoline fluid at O'Reilly.

http://www.napaonline.com/Catalog/Catalo...4017_0190428884

However the Valvoline fluid is advertised as a full synthetic. As previously noted the vis similar to full synthetic Dex 6 & Mercon LV.

According to a transmission engineer at Chrysler I spoke to he said the BW 44-44 & 44-46 fluid is just DexIII. He told me he even confirmed it with one of the transfer case engineers there.

Interesting. Have you run DexIII in one of those transfer cases? If so for how long and how well did it work?

I've contacted Valvoline, SOPUS (via Gena Fishbeck), and Royal Purple and all those companies said they have no fluid to replace Mopar Part No. 68089195AA. All those companies make an ATF that crosses for DexIII.

The OEM fluid is $30 / qt. at the closest dealer. I've found it on-line for about $20 / qt. including shipping.

The FF in my transfer case is red, but the Mopar fluid is reported to be green.

Yes I have Redline D4 in my Borg Warner 44-46 which is a DexIII replacement. I put it in at about 18k and currently have 38k on the truck. When I drained the factory fill out of the T case it was red. A friend of mine has the same truck and he bought the Mopar fluid from our local dealer and when we put it in it was red also. A while back I was thinking about sending a sample of it to Blackstone just to see. However after being told it was DexIII I didnt bother since I trusted the person who told me.
