So I'm just wondering what everybody else is running for oil in their G56??

What is the best fluid for longevity, smooth shifts and cold weather operation??

 

I got smoother shifts with amsoil atf.

 

ATF in a manual? Maybe there is something I dont know, but why would you put ATF in a manual transmission? Thanks

That is what is required in both the tranny and t-case.

 

Really? Interesting. Haven't researched it enough apparantley I know that is was the transfer cases take. Well thanks for the heads up!

Many manual trannys have been calling for ATF since Chevy (GM) first redesigned how they work back, in 1991. Tighter tolerances plus a few other changes contribute to the reason for it.

Problem with gear lubes is the EP additives eat (corrode) brass, copper parts.

I went with the synthetic amsoil ATF for tranny and TC, severe gear 75-90 in F&R Diffs.
It is better shifting even when cold (9 this week)

 

If you do lots of towing 75/140 Severe gear is better. 75/110 is also available.
