The customer states the check engine light is on.

Connected a scan tool and found codes: P0810 – Clutch Position Control Error; P0909 – Gate Select Control Error and P0919 – Gear Shift Position Control Error. With the key on, tried to select a gear and found the gear selector display flashed N. Viewed live scan tool data and found the release fork actuator current data exceeded desired values. Raised the vehicle on a hoist and removed the gearbox to gain access to the clutch. Removed the clutch from the engine and found it was worn. Inspected the clutch release bearing and found it was damaged. These tests verified that the clutch release bearing and clutch kit were faulty.

Replaced the clutch release bearing and the clutch kit, cleared codes, performed a road test and verified the vehicle operated properly. The check engine light did not illuminate and no fault codes returned.
