J 41545 Park/Neutral Switch Alignment Tool

If a new PNP switch has been rotated and the pin is broken or if you are installing an old PNP switch, adjust the PNP switch.

  1. Place the shift selector shaft into Neutral.
  2. Use the J 41545 in order to align the slots of the PNP switch to the Neutral position.
  3. Align the flats of the shift shaft to the flats in the PNP switch.
  4. Install the PNP switch to the transaxle.
  5. Important: If the PNP switch bolt holes do not align with the threaded holes in the transaxle, verify that the shaft is in the Neutral position.

  6. Assemble the PNP switch bolts/screws loosely.

  7. Object Number: 161078  Size: SH
  8. Use the J 41545 in order to align the PNP switch.
  9. 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.

  10. Install the PNP switch bolts/screws.
  11. Tighten
    Tighten the PNP switch bolts/screws to 25 N·m (18 lb ft).
