Using A New Switch

  1. Align the holes in the park/neutral position switch with the holes in the transmission control.
  2. Ensure that the transmission control is still in the Neutral position.
  3. Do not rotate the switch.
  4. The new switch is pinned in the neutral position. If the pin is missing or broken and the switch has been rotated, proceed to "Using The Old Switch".
  5. 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.

    Important: Ensure that the vehicle will only start in the park or neutral position. Readjust the switch if the engine will start in any other position.
