Hi, having an issue with the MTA transmission. The gearbox was removed to repair an oil leak.... Upon reinstsllation is now stuck in 3rd gear with the gear selection unavilable.... Scanning with multiecuscan is has given codes for eol not done and clutch bite point not set... The major fault is p1739-15 that says the clutch position sensor is short to positive or open circuit... Test proove wiring is good... But no signals are detected on the sensor pins.... The supply voltage and ground are connected.... Anyone got experience or suggestions for this fault
