| Complaint: | It might be possible that - even if the transmission is correctly adjusted- a stiff and/or inexact shift mechanism occurs especially at cold conditions. As the transmission oil becomes warmer the shifting behavior improves. This is definitely not a transmission damage, the durability of the transmission is not affected. |
|---|---|
| Cause: | Problem might be caused by: - Sliding gears are out of tolerance. - Feathering at the synchronizers. - Oil stiffness. |
| Production: | Modified sliding gears have been implemented in production since June 2002 with transmission number A10721F17. |
Remedy:
In case of customer complaint install a modified sliding gear for gear for 1st and 2nd gear. The mentioned part is available through P&A under the following Partnumber: 13123502 / Catalognumber: 90 07 140. For further parts please refer to EPC (if required).
Note:
