Transmission Position Sensor/Switch: Service and Repair

TRANSAXLE RANGE SWITCH




The transaxle range switch contains four switches that ground four different circuits. These circuits are 771 (switch A), 772 (switch B), 773 (switch C) and 776 (switch D). (The switch also contains the backup lamp switch and the neutral/start switch.)

The transaxle monitors these four circuits and determines what gear the operator has selected by the combinations of opens and grounds. Each combination indicates a specific selection in the manual shift quadrant (PRND32).

Refer to "DTC P0705 - Trans Range Switch Circuit" in the Automatic Transaxle.

REMOVAL




1. Remove air induction system.
2. Disconnect electrical connectors from selector switch.
3. Disconnect shifter cable from control lever.
4. Place control lever in the full clockwise position.

NOTE: If manual shift shaft is rotated excessively, internal damage to the transaxle range switch may occur.

5. Prevent the manual shift shaft from rotating by holding control lever while removing retaining nut from manual shift shaft. Remove control lever.
6. Remove two switch-to-transaxle case bolts and remove switch.

INSTALLATION




1. Install switch to transaxle and install switch to case bolts. Do not tighten bolts at this time.
2. Install control lever-to-manual shift shaft.

NOTE: If manual shift shaft is rotated excessively, internal damage to the transaxle range switch may occur.
