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.
