Installation Procedure

Tools Required
^ J 41545 Alignment tool





1. Verify that the transmission still is in the N (Neutral) position. If the position has moved, rotate the shaft clockwise from Park (P) through Reverse (R) into Neutral (N). 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 (PNP) 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 PNP switch installation, verify that the engine starts only in Park (P) or Neutral (N). If the engine starts in any other position, readjust the switch. Check the shifter for normal freedom of movement. Refer to Powertrain Management for diagnosis if DTC(s) are present.

2. Install the PNP switch.
^ Align the flats in the PNP switch with the transmission manual shaft flats.
^ Press the PNP 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 ft. lbs.).
