Installation

  1. Install the park/neutral position switch. When installing, tighten the bolts loosely to fix the inhibitor switch assembly (A) so that adjustment can be made as necessary.
  2. Install the manual control lever (A).
  3. Tighten the nut (B) to the specified torque.

    Tightening torque: 16.7 ~ 26 N·m

  4. After installing the manual control lever (A) in the "N" position, install the SST (09480-A3800) or a 0.1969 in (5 mm) bolt.
  5. Tighten the bolts (A) to the specified torque.

    Tightening torque: 9.8 ~ 11.8 N·m

  6. Remove the stainless steel bolt (09480-A3800) or 0.1969 in (5 mm) bolt.
  7. Install the shift cable and tighten the nut (A).
  8. Connect the park/neutral position switch connector (B).

    Tightening torque: 12.7 - 15.7 N·m
    Before tightening the nut, adjust the shift cable. (Refer to Automatic Transmission Control System - "Shift Cable")
  9. Connect the negative (-) battery cable.
