Installation Procedure

^ Tools Required
- J41545 Park/Neutral 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). Do 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





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. With the alignment tool, verify the alignment of the switch before tightening the bolts.
4. Install the bolts.

Notice: Refer to Fastener Notice in Service Precautions.

^ Tighten the bolts to 25 Nm (18 ft. lbs.).
5. Remove the alignment tool.
6. Install the shift cable and the lever.
7. Install the linkage retaining nut.
^ Tighten the nut to 20 Nm (15 ft. lbs.).
