Transmission Position Switch/Sensor: Service and Repair
Removal Procedure
1. Apply the parking brake.
2. Shift the transmission into neutral.
3. Remove the nut securing the transmission control lever to the manual shaft.
4. Remove the transmission control lever from the manual shaft.
5. Disconnect the wiring harness connector at the wiring harness.
Important: Because of the park neutral position switch lead connector breaking when disconnected, disconnect the harness connector at a point near
the vehicle harness, not at the park neutral position switch lead.
6. Remove two bolts securing the park/neutral position switch to the transmission.
7. Remove the park/neutral position switch from the manual shaft.
Installation Procedure
1. If the park/neutral position switch did not slide off the manual shaft, file the outer edge of the manual shaft in order to remove any burrs.
2. Install the switch to the transmission manual shaft by aligning the switch hub flats with the manual shaft flats.
3. Slide the switch onto the transmission manual shaft until the switch mounting bracket contacts the mounting bosses on the transmission.
4. Install the switch to the transmission with two bolts. Do not tighten the bolts.
