Hva betyr feilkoden?

Shift fork 3 is jammed and stays put when the TCM asks for a shift. The cause may be a damaged shift fork, a damaged position sensor, or a lack of hydraulic pressure to the shifting system.

Mulige årsaker

Damaged shift fork
Damaged position sensor
No hydraulic pressure to the shifting system

Hva du kan gjøre

1Read out the fault codes from the transmission control module; if a code concerns hydraulics or a position sensor, trace that one first
2With diagnostic equipment, run the control routine with the engine on, the parking brake applied and the selector in P, and listen for a clonking sound
3If several forks stay put, the fault is in the mechatronic unit, which a workshop should replace
4If only the position sensor for shift fork 3 misses its position but the clonking sound is heard, the sensor is at fault
5If there is no clonking sound and the sensor does not move as required, a mechanical fault in the transmission is likely; a workshop should check it
6Have a workshop check that the control module has the latest software before the car is returned
