Hi guys, long story short, 2022 Denali, 6.2, runs great, shifts fine, UNTILL I give it the juice. If I'm at lower speeds and hit it, the trans feels weird , like it's bumping or almost slipping, does it 80 percent of the time, normal city driving it seems fine, but when I punch it to get on the highway, etc I get the weird bump/slip. Anyone else have this issue or heard of it?
