One way is you start to accelerate and then you don;t give it much gas and then you accelerate and it shudders ( vibrates ) . Happens alot going up inclines , between 1200-2000 rpm . Another incident happenend the other day on the highway , was in middle lane and had to slow down because of a car in front of me while I was looking to change lanes , so rpms went into that range again and when I was able to change lanes and accelerated the car shook for about 5-6 seconds then the car kicked in and took off , It seems that when the transmission wants to either go into a lower or higher gear and you give it gas it shakes/shudders ( you can actually feel it in the steering wheel) . when I made the appoinment the other day I briefly described the problem and that I have the Technical service bulletin from GM that was given on this thread ( this is such a valuable website for us owners ) and the delaer said to bring it in . From reading other posts I hope I don;t get a run around - but I know the sales manager who ordered the car for me back in Oct 2011 . I will keep you all posted on what happens .
