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.
