What does this fault code mean?

Shift fork 3 moves away from the N position without the transmission control module (TCM) having requested it. The cause may be a hydraulic fault or a damaged position sensor, and both can be in the mechatronic unit.

Possible causes

Fault in the hydraulic system
Damaged position sensor

What you can do

1Read out the fault codes from the transmission control module again to see whether the fault is in the transmission or in the mechatronic unit
2If you have diagnostic equipment, check the position value for shift fork 3 in live data while the selector is in N
3A workshop should replace the mechatronic unit, since both possible faults are located there; then road test and check the code
