    Used M1 75W-90 in my front diff and transfer case, but was hesitant about using any GL-5 oil in my transmission because I read the sulfur additives tend to corrode brass synchros. HOWEVER, the owner's manual says that you can use GL-4 or GL-5, so I think that as long as the recommended change intervals are followed, it's safe to use.

    I used Redline MT-90 in my 5-speed.
