To install the cable, follow the reverse order of removal, being careful not to damage the rubber boot. For adjustment, apply the parking brake and remove the retaining clip from the rear support bracket. Separate the body-core adjuster from the range selector pin and place the transmission shift selector shaft and lever in Neutral. Remove the horseshoe retainer from the shift cable and the cable from the transmission oil pan clip. Reinstall the cable onto the transmission oil pan clip and the horseshoe retainer onto the shift cable. Ensure the transmission shift lever and selector shaft are still in Neutral and snap the body-core adjustment onto the transmission selector shaft. Push the locking tab into the body core until it snaps, and insert the horseshoe retainer into the shift cable. Finally, check the adjustment to ensure the shift lever goes into all positions and the engine starts only in the P or N positions. Readjust the shift cable and park/neutral switch if necessary to meet these criteria.
