Have the new 15 Denali with the 6.2. Have 2000 miles on the truck now and I'm starting to notice transmission slop. Mostly in traffic. It seems like it bangs gears a lot. Also when I slow down it seems like grade braking is active and that should only be on with tow mode.

Is anyone having the issues that I am facing? If yes what was done about it. The dealer said that this is normal.
