just to make sure i need MTL and 75w90 right? 3 of MTL and 2 of 75w90? if someone could just verify that for me thanks!

 

yes I use that as well and it has been proven beneficial for me countless times .
To verify, you need 3 of the MTL for the big tranny and 2 of the 75w90's for the front and rear diffs. It's .55qts for the front and rear diffs each and 2.9qts for the big tranny. GL-4 for the big one and GL-5 for the little ones, thats how I remember. It says it right on the label of the oil so its dummy proof.
