Was bedeutet der Fehlercode?

The transmission control module (TCM) has received a signal that two odd gears are engaged at the same time. The transmission has a mechanical interlock function that is meant to prevent this, so the fault is hard to trace. The position sensor or the interlock function may be damaged, but the fault often occurs together with a hydraulic fault.

Mögliche Ursachen

Damaged position sensor
Interlock function damaged along with a hydraulic fault

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
2Checking the sensor alone is not enough, because the fault often occurs together with a hydraulic fault
3Since the hydraulic fault may be inside or outside the mechatronic unit, the whole transmission has to be replaced; have a workshop do this
