Incredible pile of shit... yes i totally agree. Wot it shifted okay... but I'm.sorry I don't drive wot all day long... or at all like a performance car that is 2000 lbs lighter will be driven. Now it's been superseded by the 10 speed which all the Vettes and Camaros will run .. so why bother lol. Wouldn't surprise me much if gm drops the thing completely lol.

Yeah but the trans as a solitary piece of hardware is great imo. Just think GM really screwed up the tuning and electronic controls of it.

It’s not like a problamatic trans for everybody either. Which leads me to believe there were some manufacturing defects a long with the worlds worst tuning.

Seriously I think GM has some of the worst factory tuning out of any company out there. It’s amazing how good the hardware can be and how bad the end result can be.

Oh I agree... it's why I made the statement I did about the 10 speed. The 6R80 in the Ford shifts pretty good...and it's basically a 6L80e as an example. The 10 speed may be the same way.. shift great in Ford's and then Gm will make a mess of it with their shitty tuning. I said years ago they should fire whatever clowns they have write their maps and hire the Ford guys lol. They aren't perfect either but it's leaps and bounds better than the rubbish gm does. That said tuning did not fix my 8 speed pile and gm wouldn't put a new trans in the truck so I fixed it by unloading it lol.

I drove my brother in law's 6.2 sierra Denali 8 spd and was not impressed. Definitely like the 6spd in my 5.3 Silverado better.
