Initial publication
• Rough gear changes, both when accelerating and when slowing down.
• There is a rough driving power disruption that occurs sporadically and lasts for less than a second.
Technical Background
After a mechatronics, torque converter, or complete gearbox replacement, the clutches must be adapted to the
new component. 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.

Service
1. As with any shift concern, check the fluid level and condition.
• If the fluid level is low, correct the level then test drive to confirm the issue still exists.
• If burnt or contaminated fluid is found, call the Technical Assistance Center before doing any repairs.
• If fluid level and condition are okay, proceed to step 2.
2. If a mechatronics unit, torque converter, or complete gearbox were replaced, ensure that the clutches have
been adapted. Adaptation of the clutches may also be necessary after certain software updates or if the
adaptations have been cleared. Follow the procedure in Elsa or through Guided Fault Finding to start the clutch
adaptations toward full adaptation.
