I have a 3/4 ton GMC 2004 with the 6.0L.Question:  Back in April I changed thetransmission fluid in the transfer case. I was told at the parts house it took Atf-4 synthetic transmission fluid. I added the transmission fluid. Drove the truck from April to the end of May. Now my transfer case is burned up and has a whole in the transfer case. Would this transmission fluid burn my transfer case up. Being the wrong transmission fluid?Answer:  The ATF will not case the problem, the problem was caused by the pump wearing a hole in the rear case.As a minimum you will need the following parts:
