This requires a gradual move of the clutch linings toward the optimal operating points in the most diverse load conditions. As a result, sporadic driving power disruptions lasting for less than a second or reduced shift comfort are possible over the first 500 miles. This is normal, and these issues will decrease over time. The issues can also occur if the adaptation values of the gearbox were deleted.
