17 Silverado High Country Jerking

[highcountry09]

Hello I would like to get a couple suggestions or answers on my 2017 Silverado High country 6.2L , I just purchased it about month ago. When I first brought it , I had horrible vibrations on the steering wheel while hitting the gas slowly at low speeds and highway speeds. Dropped it off my dealership , they replaced torque converter, valve body and new trans fluid. I received it back and everything shifts normal , no more vibrations on low end or high ends speeds. Only problem I’m having now is if I do a quick stop/ go , you can feel the car jerk when applying gas at that low speed almost feeling like it’s banging in a low gear and if I go over speed bumps and hit the gas slowly , it almost feels like the truck throws me/ jerks me. If I come to a complete stop then take off , it won’t happen at all. It will happen here and there no always , must at quick stop/ go or going over speed bumps. Thank you

Sounds like they could have let the drive shaft loose or transmission mount loose
