My 2018 Sierra (1 month old) has an issue on the first 10-15kms in the morning, its changing gears up and down constantly making the truck feel like it’s rocking back and forth, then completely goes away after the first 10-15 kms. It only has 4000 kms on it. It didn’t take me long to see it’s not all that un-common, and the dealer was extremely helpful during this ordeal. Hoping for the best.
