PARKING FUNCTION

•

By setting the select lever to the P range, the parking pawl is engaged with the parking gear and fixes the

output shaft.

•

By the movement of the select lever, the manual shaft on the side surface of the AT is moved. The

manual plate and parking rod in the AT are interlocked with the manual shaft. When the manual shaft
moves, the parking rod end pushes up the parking pawl.

•

The parking pawl is engaged with the parking gear when pushed up, and fixes the output shaft.

•

When the clutch is disengaged, it returns to the original position by the force of the return spring fixed to

the parking pawl.

INHIBITOR SWITCH

•

The inhibitor switch is installed on the right side of the transmission main unit to detect the select lever

position.

•

The inhibitor switch is connected with the starter SW circuit. The engine cannot be started when the

select lever is at any position other than the P or N range.

•

By moving the select lever, the combination of the inhibitor switch pins is changed. The current range of

TCM is detected based on the combination of the pins.
