GM was having a hell of a time getting their 6 speeds tuned correctly too when they first came out. A friend of mine had a 2007 Yukon Denali with the 6.2 and 6 speed, that thing was non stop with tranny issues, driveline lash issues, they eventually had to replace the engine block because it had a slight crack somewhere and was leaking coolant. I always remember it being the weirdest thing when he first got it, if you were cruising and floored it the trans would try to upshift, then get confused, then downshift.
That truck swore him off GM after owning a few GM products and that's not even getting into all the other issues it had.
Yeah my 2016 Colorado was horrible! Clunks and bangs. You'd give it gas and it wouldn't want to go. Or you'd be cruising at about 25 and give it gas and it would clunk real loud and start going. This 8 speed is a breath of fresh air.
