Shift Cable: Adjustments
4T80-E - Automatic Transaxle
Range Selector Lever Cable Adjustment
Notice: Adjust the shift control cable only while the transaxle and the gear selector are in NEUTRAL. Failure to do so may cause mis-adjustment.
1. Set the parking brake and chock the wheels.
2. Remove the shift cable terminal from the transmission manual shaft lever pin.
3. Pry on the shift cable terminal at the manual shaft lever pin with an appropriate tool. Prying or pulling up on any other part of the shift cable may
result in damage to the shift cable.
4. Fully lift the adjuster lock button. Ensure that the adjuster is free to move.
5. Place the transmission manual shaft lever in (N) Neutral. In order to find (N) Neutral, rotate the lever fully counterclockwise to (P) Park, and then
clockwise 2 clicks into (N) Neutral.
6. Place the gear shifter inside the car to the (N) Neutral position. Use the transmission shift indicator on the console to find (N) Neutral.
7. From under the hood, grasp the shift cable terminal and pull it toward the pin on the manual shaft lever. The shift cable adjuster spring should
compress as the terminal is moved toward the pin.
8. Attach the pin to the lever by pushing down carefully until it snaps.
Do not pull the terminal beyond the pin and then push back. This action could move the shifter out of (N) Neutral.
9. Press the adjuster lock button down flush with the adjuster body.
10. Shift to (P) Park and release the parking brake while applying the service brake.
11. Start the engine and assure all of the indicated gear positions match the vehicle response.
