I got 2014 Silverado with 35k been having similar issue since purchased. Dealer Tech said it was due to the low RPM vs speed the tyranny and the computer are caught like in-between actions. Applying more pressure on accelerator helps alleviate it. OK, but when in slow city traffic that action is not the answer, so you have to slow vehicle down to stop the vibration, this is very annoying. Other than that no issues accelerating for hwy entry or passing. Still, it is very annoying.
