Wanting To Switch Trans, Diffs, & Transfer Case To Amsoil?

[iceman1998]

Hey guys, i have an 2007 GMC Sierra with a 5.3 and 4 speed auto. I want to change my fluids in the Trans, Diffs, and Transfer case to Amsoil. My question is do i need to and any additives to the diffs for the limited slip? Do i need to add anything to the the trans or Transfer case? Any help would be great.

No additive for the limited slip. There is a TSB out about it. All should be just drain and refill. Make sure that you change the trans filter.

If you have the Auto transfer case then you need to use the AutoTraK II, Here is the write up on how to do that. The rest is pretty easy, no additive to the differential oil and you can run the new ATL fluid which is the dexron VI fluid for the transmission.

AutoTrak II does not go in the 900 series, says my Owners Manual and the dealer, careful. 900's take Dex 6

 

The amsoil severe gear for the diff's is great, highly recommend!
