Seems like others are having the same issue on other forums too. The “fix” is an aftermarket tuner is what I’m being told. Only happening in the 5.3 8 speed. This is my 7th Chevy Silverado. It’s a very noticeable lag and jerk when I’m at low speeds. Also told it may be the engine relearning. I only have 1500 miles on mine so, I guess time will tell.

Anyone else experiencing a hard shift or hesitation of the engine when you first hit the gas. For example, I start the truck, reverse out of the driveway, put the car in drive and when I hit the gas, the truck goes toward and then i feel the truck completely stop for a second (hesitation) and then it continues forward, I only expierence this when I’m going from reverse to forward. I come to a complete stop and do not shift to drive when moving backwards still. ?
