Apparently they dont even use the mopar fluid haha. I'm going to stick with the amsoil though, seems like the best bet.
Stick with the signature series atf for the transfer case and 75w- 85 for the diff's.
As for the transfer case, it's just drain and fill. Open the fill plug, then the drain. Let it drain out till it's just dripping. Tighten up the drain plug. I used a suction pump to put the fluid back in. I wanna say it's 25 ft lbs for all the plugs, but I could be wrong. If you google it you can find the spec for the tightness. It should be 2 qts, but just fill till it starts weeping out.
I did mine at 50k and I honestly could have gotten a lot more life out of the fluid that was in there. Like probably another 25k.
