p1780
Have a 2003 550 Service Truck that when I just scanned it had code p1780. Transmission Control Switch (O/D cancel) Circuit out of Self Test Range. My Mechanic that drives the truck has complained that the truck has sporadic power loss. Would this code effect performance? What sets this code off? And what corrective messures can be taken.
