Park/Neutral Position Switch: Installation

  1. Install the switch to the transmission manual shaft by aligning the switch hub flats with the manual shaft flats. Slide the switch onto the transmission manual shaft until the switch mounting bracket contacts the mounting bosses on the transmission. See Fig 1.
  2. NOTE: Do not tighten the bolts at this time.
  3. Install the switch to the transmission with two bolts finger tight. Position the tool (J-41364-A) onto the PNP switch. See Fig 2. 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. Rotate the tool until the upper locator pin on the tool is lined up with the slot on the top of the switch.
  4. Tighten the bolts securing the switch to specification. See TORQUE SPECIFICATIONS . Remove (J-41364-A) from the switch. Connect the electrical connectors to the switch. Install the transmission control lever to the manual shaft with the nut.
  5. Tighten the control lever nut to specification. See TORQUE SPECIFICATIONS . Lower the vehicle. Check the switch for proper operation. The engine must start in the PARK or NEUTRAL positions only. If proper operation of the switch can not be obtained, replace the switch.
