Park/Neutral Position Switch Replacement and Adjustment
« on: February 18, 2008, 13:58:39 PM »

Park/Neutral Position Switch Replacement

Tools Required
J 41364-A Park Neutral Switch Aligner

Removal Procedure



1. Apply the park brake.
2. Shift the transmission into neutral.
3. If equipped with 4-wheel drive (4WD), remove the front propeller shaft.
4. Raise and suitably support the vehicle.
5. Disconnect the park/neutral position (PNP) switch electrical connectors (2).
 


6. Remove the manual shaft lever nut.
7. Remove the transmission control lever from the manual shaft.
8. Remove the PNP switch bolts.
9. 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 the park neutral switch aligner will not be necessary.


3. Install the PNP switch bolts finger tight.
 


4. Install J 41364-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
Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.


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 lb ft).

6. Remove the J 41364-A from the switch. If installing a new switch, remove the
    positive assurance bracket at this time.
 


7. Install the transmission control lever to the manual shaft with the nut.

    Tighten the nut to 25 Nm (18 lb ft).


 
8. Connect the PNP switch electrical connectors (2).
9. If equipped with 4WD, install the front propeller shaft.
10. Lower the vehicle.
11. Check the switch for proper operation. The engine must start in the park (P) or
      neutral (N) positions only. If proper operation of the switch can not be obtained,
      replace the switch.

Important
  • The following procedure is for vehicles that have not had the park/neutral position (PNP) switch removed or replaced. If the PNP switch has been removed or replaced, refer to Park/Neutral Position Switch Replacement for the proper adjustment procedure.
  • Apply the park brake.
  • The engine must start in the park (P) or neutral (N) positions only.
  • Check the PNP switch for proper operation. If adjustment is required, proceed as follows:


1. Place the transmission range selector in the neutral (N) position.
2. With an assistant in the drivers seat, raise and suitably support the vehicle.
3. Loosen the park/neutral position (PNP) switch bolts.
4. With the vehicle in the neutral (N) position, rotate the switch while the
    assistant attempts to start the engine.
5. Following a successful start, turn the engine off.

Notice
Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.



6. Tighten the PNP switch bolts.

    Tighten the bolts to 25 Nm (18 lb ft).

7. Lower the vehicle.
8. Check the PNP switch for proper operation. The engine must start in the park
    (P) or neutral (N) positions only.
9. Replace the PNP switch if proper operation can not be achieved.
