Fluids recommendation?

[mconstable]

Hello again, per my previous thread, I have very limited internet access, or I'd do a search for this info.

Just wondering what are the highest recommended fluids for...

T-Case

6-Spd transmission

Front and rear diffs.

Thanks guys!!

Also, which won't cause warranty issues?

I just replaced those fluids yesterday after work. Used Redline MTL in the transmission, and Amsoil gear lube in the diffs (FGO rear & FGR front), and Amsoil ATF in the xfer case.



I was surprised to find almost no mud on the differential magnets from my last change 20k ago (Amsoil TGR).



I am trying out MTL for the first time; I used Amsoil 5W-30 last time and had no problems/issues with it.



edit: you'll need a 17mm hex to remove the transmission fill plug; and a 9/16" wrench to remove the PTO bolt(s). I think it was 3/8" hex to remove the xfer case plugs. 13mm socket to loosen/remove the diff covers - torque them to 30 ftlbs.

I'm using Royal Purple Syncromax in trans & transfer case.

RP Max-Gear 85/140 in the rear 80/90 in the front.

I am running amsoil in all my orifices. I had good luck with my 03 6 spd using it. It seemed to shift a little easier.
