Air Induction System:
1. Remove Air Induction system.
Assembly View:
2. Disconnect electrical connectors from selector switch.
3. Disconnect shifter cable from control lever.
4. Place control lever in the full clockwise position.
NOTE: If manual shift shaft is rotated excessively, internal damage to the park/neutral position switch may occur.
5. Prevent the manual shift shaft from rotating by holding the control lever while removing retaining nut from manual shift shaft. Remove control lever.
6. Remove two switch-to-transaxle case bolts and remove switch.
INSTALLATION
1. Install switch to transaxle and install switch to case bolts. Do not tighten bolts at this time.
2. Install control lever-to-manual shift shaft.
