Transmission Position Sensor/Switch: Service and Repair

REMOVAL PROCEDURE
1. Set the parking brake.
2. Set the gear selector to N (Neutral).
3. Remove the electrical connector.
4. Remove the linkage retaining nut.
5. Remove the cable and the lever.
6. Remove the park/neutral position switch.

INSTALLATION PROCEDURE






^ Tools Required:
- J 41545 PNP Switch Alignment Tool

1. Verify that the transmission still is in the N (Neutral) position. If the position has moved, rotate the shaft clockwise from P (Park) through R (Reverse) into N (Neutral). Be careful not to damage the shaft flats, corners, or threads.
- New replacement park/neutral position switches already are pinned in the N (Neutral) position.
- When installing a park/neutral position switch with a sheared pin, insert the alignment tool into the 2 slots on the switch in the area of the transmission shaft.
- Rotate the tool until the rear leg on the tool falls into the slot on the switch near the hose.
- Verify that the tool is seated properly in all 3 slots.
- Remove the tool.
- Check for a cracked carrier if either of the following conditions exist:
^ The pin is sheared
^ You are installing the original switch

Important: After the park/neutral switch installation, verify that the engine starts only in P (Park) or N (Neutral). If the engine starts in any other position, readjust the park/neutral position switch.

Important: Check the shifter for normal freedom of movement. Refer to POWERTRAIN MANAGEMENT for diagnosis if DTC(s) are present.

2. Install the park/neutral position switch.
- Align the flats in the park/neutral position switch with the transmission manual shaft flats.
- Press the park/neutral position switch onto the shaft. Fully seat the switch against the transmission.
3. Install the bolts.
4. With the alignment tool, verify the alignment of the switch before tightening the bolts.
- Tighten the bolts to 25 Nm (18 lb ft).

NOTICE: Always use the correct fastener in the correct location. When you replace a fastener, use ONLY the exact part number for that application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems.

5. Remove the alignment tool.
6. Install the cable and the lever.
7. Install the linkage retaining nut.
- Tighten the nut to 20 Nm (15 lb ft).
8. Connect the electrical connectors.
