SYSTEM DESCRIPTION

The TCM uses the vehicle speed signal to determine the actual gear position (1st, 2nd, 3rd, 4th, 5th or 6th gear).

Then the TCM compares the actual gear with the shift schedule in the TCM memory to detect mechanical problems of the shift solenoid valves and

valve body.

MONITOR DESCRIPTION

The TCM commands gear shifts by turning the shift solenoid valves on or off. According to the input shaft revolution, intermediate (counter) shaft

revolution and output shaft revolution, the TCM detects the actual gear position (1st, 2nd, 3rd, 4th, 5th or 6th gear position). When the gear position

commanded by the TCM and the actual gear position are not the same, the TCM illuminates the MIL.
