  5. Remove the transmission range switch.
  6. Make sure the selector control shaft is in the N position. If necessary, move the shift lever to the N position.
    NOTE: Do not use the selector control shaft to adjust the shift position. If the selector control shaft tips are squeezed together it will cause a faulty signal or position due to play between the selector control shaft and the switch. The clearance (A) between selector control shaft tips is 2.0 mm (0.08 in.).
