After only having this new truck for 2 days the transmission was taken out of it due to a ticking noise in the engine. The mechanic was advised by GM to take out the transmission and replace a flywheel. After 2 weeks of waiting for a part I picked up my truck. The next day the noise was back. I have had 2 GM reps listen to the noise. The secound rep told me that it was "entrained gasses" and that there was nothing they could do about it. I did not purchase this truck making the noise and do not want it anymore after the transmission has been taken out.
