ok i know what to put in the tranny but the package i bought from maperformance came with 2 quarts of 75w90 oil for the rear differential and transfer case. one of the quarts has an "NS" after the weight and the other says high performance gear oil. which one goes in the rear diff and which one goes in the transfer case?

 

I'd call Red Line if I were you :-) Or Shep Racing :-p Tell us what you find out either way lol

 

the NS is the no limited slip compatability which some ppl have said is used in the x case

 

The rear differential and transfer case both call for the LSD version of fluid, but you could probably get away with using the NS in the transfer case. Personally, if I were you, I'd ask MAP to send you a correct bottle of GL-5 75W-90 and return the NS bottle.

 

For TC Im using only diaqueen gear oil
