Transfer Case And 5spd fs5r30a manual oil

[ThatOneNissanGuy]

Its the 2nd year with my r50 thus my 2nd maintenance,when i got the truck i didnt check either tc or mt oil,what compound does it have and where do i drain it

The transfer case takes ATF (Dex-Merc), and the manual transmission takes GL-4 75W90. Make sure it's GL-4! GL-5 rated oil (which is much more common) will eat the synchros.

 

The drain plugs should be pretty obvious once you're under the truck.

Draining the tranny is the easy part, filling it up is a bit of a pain unless on a rack.

My one tip is to make sure you can get the fill plug loose before draining the oil.

Good tip, especially for the rear end.
