I would like to find someone in the DC area with a new GT, manual transmission, to compare to mine. I still get a 'thunk' sound (like drivetrain lash) when I go from decelerating to accelerating. I can hear it especially in 3rd gear going around 15-20 mph.
The dealer told me it's just the way they are. But I'd sure like to hear it in another GT to feel a little more confident about what the dealer says.
