transmission question 2020 canyon denali

[cuznjohn]

hi everyone, i go by cuznjohn, and lease a 2020 canyon. the first day i left the dealer, about 3 weeks ago, the transmission slipped from first to second gear. then after that, all was good. the next morning i went to go out in the truck, and it happened two more times. i went back to the dealer, told them what was going on, and a mechanic came out with a computer, hooked up to the car, took it for a ride, felt the slipping, and said the truck transmission is learning, and it could be 5k in miles to learn. i have never heard of this. is it true, and can the service dept. turn this feature off. i hate it. it happened once trying to get on a parkway, and the guy coming up on me, had to hit his brakes hard, and called me a pretty bad name. any help would be greatly appreciated. thanks

It’s an 8 speed most likely, they shift like that. No repairs right now for it. Do what they say for now and evaluate at 5k miles.
