Was bedeutet der Fehlercode?

Shift fork 3 or 4 travels the wrong way compared with the one the TCM has requested. The cause lies in the second hydraulic valve for forks 3 and 4 or in the control solenoid for the valves, and the fault means the mechatronic unit must be replaced.

Mögliche Ursachen

Damaged second hydraulic valve
Damaged control solenoid for the hydraulic valves

Was Sie tun können

1Read out the fault codes from the transmission control module and deal first with any codes that may share the same cause
2The fault means the mechatronic unit must be replaced, and a workshop should do this
3If the control module is also replaced, it must be programmed by a workshop, because a replacement control module arrives without software
4Then read out the fault codes again to see whether the fault code remains
