changing diff, trans, transfer case fluids...

[L0ckett]

Okay so I'm going to be changing the fluids in the differential, transaxle, and transfer case this weekend. I have a gallon of 80w90 gear oil. Would I be able to use this to replace all three fluids? I know I can use it for the diff and transfer case but read that the transaxle uses mt90 or similar. Would it be okay to run the stuff I have in all three?

Thats enoug for the transfercase and the rear diff yes. But I wouldnt run that in your transmission at all. Get some mt90 for the trans.

80w90 has been working fine for about 3,000 miles so far. But this is a built transmission.
Make sure it's GL4 and you should be a-okay!
