I am replacing my manual transmission and transfer case oils with Redline. I am putting MT-90 (GL-4 75W90) in my transmission and was also going to put it in my transfer case. The FSM recommends the same fluid for both the transmission and transfer case..."API GL-4 or GL-5, SAE 75W-90 or 80W-90".
Should I run the GL-4 or GL-5 in my transfer case (75W90)? Redline's website doesn't have any oils specifically listed for "transfer cases".
If you know, what do you run in your transfer case?
Thanks
*Forgot to mention its the W56 transmission...not sure the # on the T-case.
