Not sure why this member dosnt. My wife went from a ‘15 slt (6 speed) to a ‘16 Denali with the 8 speed. The 8 speed is hands down better in every way. Not sure if it has anything to do with the 6.2 vs the 5.3 or not, but the 8 speed in her car shifts fantastic and just floats along at all speeds. I am willing to bet the 10 speed is even better yet.
Sorry for the delay in responding, my 8 spd has an occasional hesitation in lower gears, often when pulling away from a stop. Had the dealer flash it so it would “relearn” shift points but it’s still there. I did drive a 10 speed Expedition as a rental and that was flawless.
With respect to the wheels, we’re due for new rubber shortly so hopefully things improve there as well.
