Just had to replace circulate T/O bearing on a selespeed cfc319 transmission that gave the code p7139-15....the clutch was working prior to the gearbox removal to attend to a oil leak on a cover and tcen being reinstalled ..... After queries at Valeo the manufacturer of the 55239548 they say the position must be set before dismantling.... Can anyone comment or advise

What did transpire was the post cat sensor and the cps have identical connectors snd were swopped at a stage of the diagnosis... Could that be the cause of the failure.... And incidentally niw gives intermittent o2 sensor errors... Maybe that ecu is dammaged by the cps bring erroneusly connected to it...
