Gear Shift Changes, particularly in first and second gears Information: Rough gear changes with unmatched engine and transmission revs can be attributed to an unadapted PDK. Transmission performance issues characterized by unmatched, abrupt shifts, particularly in first and second gears may require a driving adaption.
