    Default GM Autotrac II fluid only or are there others?

    Before I sold my Yukon, I changed the transfer case fluid. I was informed that you can only use GM autotrac II transfer case fluid in it or I am running a huge risk of destroying my transfer case. Is this true or are the dealerships B.S. me. I did inquire at autozone and advance auto about what fluid to use and the capacity and their systems show it to be a dealer item only. Just curios for future reference.

    If it is a manual shift case, put ATF in it. Otherwise put Autotrac in it. You'll burn up the clutches in an auto shift case with ATF.

    Yup, the 246 needs that expensive blue stuff.
