I am having RRE change my fluids next week. I already know I use Redline MT-90 for Trans, 75w90 (non-shockproof) for the Diffs. What Redline oil do I use for the transfer case?

Thanks for the help!

 

The x-fer case is the same as the center diff, you would use the 75W90 in the center and rear.

 

Yup, although you can go Shockproof in the transfer if you're really wanting to use it. The transfer doesn't have any clutch surfaces in it like the rear diff does. I'd just stick with 75W90 though, and will do exactly that the next time I change my fluids.

 

Thanks for the help guys!

 

n/p. If you get a chance to take some pics of the rear diff fluid change (and give some tips on filling, being that the angle is kind of awkward) please post them up! Thanks.

 

webguy: I bought a little fluid pump from my local Harbor Freight that has a nozzle on the end that fits almost perfectly into the fill holes. I just fished the tube between the xmember and the sway bar and shoved it into the fill hole. I can change the rear diff fluid in like 10 minutes with that thing.

That little pump was also so much easier than trying to snake a long hose down through the engine bay and into the fill holes of trans and transfer, too (I tired and it sucked). I'd recommend getting one if you can find it. I guess an auto parts store or hardware store might carry something like it.

 

Fantastic idea, I'll pick one up for sure! Thanks.
