what fluid is everyone using for front diffs, rear diffs, and transfer cases? i know dodge says to used synthetic 75/90 for the diffs and add an additive of theirs if you have a limited slip. and the mopar atf +4 for the tcase but what are you guys using? royal purple?

 

Royal Purple ATF+4 in the t-case, 75-90 in the diffs. It has a limited slip additive mixed in, so no need to add any.

 

You don't need any type of additive in an AAM because there aren't any clutches. I used Red Line last time, and put Mopar ATF+4 in the transfer case.

 

Valvoline synthetic.

Amsoil in the diffs. No where in my FSM does it call for an additive in the rear diff., it is a gear type LSD not a clutch type.

 

Valvaline premium blue in motor, Valvaline syn in the auto, Mopar ATF+4 in trans case and Royal Purle 75-90 in diffs.

 

There is only one, AMSOIL.
