Best oil for G56

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??

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

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.
