And I’ll add that I have a direct comparison in that she had a Denali with the 8 speed. The 8 speed was trash compared to the 10.

thank you

there is a massive amount of negative stuff on the 8 speed.

Dealer admits "not our best"...

for some people it doesn't bother them, it's the shifting

a luxury truck shouldn't shift harsh...it bothers me greatly
