Yeah my SEP09 G6 Lim Edit is doing the same thing. Severe clunk both into and out of neutral or park. My vehicle also has a very annoying vibration whenever the lock up clutches lock up,, read constant vibration at cruise speed. Ford have declared that it is a "CHARACTORISTIC" of the 5SPD and that they will not do anything about it. Will see them in court if we have too,, unfortunately. Love the car in every other regard
