another tranny fluid question

[nh98gsx]

I want to change all of the fluids in my tranny, transfer, and rear diff, and i am looking for some opions on what i should use.
i have not put any fluids in yet, currently i have 3 qts of GM synchroshift, 1 qt of redline MTL, and 1qt of amsoil 75w-90 gear lube.
i'm going to use the GM in the tranny, and the 75w-90 in the rear diff. but what do you recommend to use in the transfer case, the GM synchro, or straight MTL?

put the same stuff that you are putting in the rear end in your tranfer case. It also takes the heavy gear oil.
