P0780 HONDA Description
The Transmission Control Module (TCM) monitors the transmission mechanical shifting through various sensors. This malfunction is detected when the A/T does not shift as instructed by the TCM. This is not caused by electrical malfunction (circuits open or shorted) but by mechanical malfunction such as control valve sticking,improper solenoid valve operation, etc.
