We purchased this SUV less than two years ago and at about 50k miles the transmission started shuttering while driving. Finally we were out and it was running fine then all of sudden the car would not go into gear,check engine light came on and we were stuck. Took directly to dealer after three weeks of no response from the local dealer nor Chevrolet they finally said that they thought the valve body and torque converter were bad. We wish we never would have bought this vehicle. Chevrolet didn't seem to mind that their 2 year old vehicle had transmission problems. I have never owned anything other than gm vehicles and I promised them this would be my last and they didn't care. She told me well we are all entitled to make those decisions.
