Park/Neutral Position Switch Replacement

^ Tools Required
- J 41364-A Neutral Position Adjustment Tool

Removal Procedure





1. Apply the park brake.
2. Shift the transmission into neutral.
3. If equipped with four wheel drive (4WD), remove the front propeller shaft.
4. Remove the transmission control lever to manual shaft nut.
5. Remove the transmission control lever from the manual shaft.
6. Disconnect the park/neutral position (PNP) switch electrical connectors.
7. Remove the PNP switch bolts.
8. Remove the PNP switch from the manual shaft. If the PNP switch did not slide off the manual shaft, file the outer edge of the manual shaft in order to remove any burrs.

Installation Procedure





1. Install the PNP switch to the transmission manual shaft by aligning the switch hub flats with the manual shaft flats.
2. Slide the PNP switch onto the transmission manual shaft until the switch mounting bracket contacts the mounting bosses on the transmission.

Important: If a new PNP switch is being installed, the switch will come with a positive assurance bracket. The positive assurance bracket aligns the new switch in its proper position for installation and the use of neutral position adjustment tool will not be necessary.

3. Install the PNP switch to the transmission with two bolts, finger tight.





4. Position the J41364-A onto the PNP switch. Ensure that the two slots on the switch where the manual shaft is inserted are lined up with the lower two tabs on the tool.

Notice: Refer to Fastener Notice in Service Precautions.

5. Rotate the tool until the upper locator pin on the tool is lined up with the slot on the top of the switch.
^ Tighten the bolts to 25 Nm (18 ft. lbs.).
6. Remove the J41364-A from the PNP switch. If installing a NEW switch, remove the positive assurance bracket at this time.
7. Connect the PNP switch electrical connectors.





8. Install the transmission control lever to the manual shaft with the nut.
^ Tighten the nut to 25 Nm (18 ft. lbs.).
9. If equipped with 4WD, install the front propeller shaft.
10. Check the PNP switch for proper operation. The engine must start in the P (Park) or N (Neutral) positions ONLY. If proper operation of the switch can not be obtained, replace the switch.
