Was bedeutet der Fehlercode?

The transmission control module (TCM) has found that the adapted engagement pressure for one of the clutches is outside the permitted range. The transmission has two clutches, clutch 1 for odd gears and clutch 2 for even gears. The pressure is measured by pressure sensors and must stay within a tolerance.

Mögliche Ursachen

Leak in the hydraulic system
Dirt in the hydraulic system

Was Sie tun können

1Read out the fault codes from the transmission control module. If fault codes for the solenoids are stored, a workshop should replace the mechatronic unit
2Look for oil traces or signs of a leak under the transmission, since a leak or dirt in the hydraulic system can give the wrong pressure
3If the fault remains after the mechatronic unit has been replaced, the transmission must be replaced, and a workshop should do this

Symptome, die Sie bemerken können2
