Key will not turn in ignition and shifter will not come out of park. Rocking car fixed problem once and jacking up front of car fixed it once. What needs my attention?

There is a procedure for adjusting the shift cable, as well as the park lock cable. I would start with those considering you can get it to function.

Range Selector Lever Cable Adjustment

Caution: Refer to Automatic Transaxle Range Selector Cable Caution in Cautions and Notices.

Notice: Adjust the automatic transaxle range selector cable while the transaxle and while the gear selector are in the Neutral position only. Failure to do so may cause mis-adjustment.

1.

Set the parking brake.

2.

Block the wheels.

3.

Disconnect the shift cables at both ends with the system in Neutral.

Notice: Do NOT attempt to separate the metal couplings. Replace both cable pieces if the metal couplings are separated. Both of the cable section will be damaged if the two metal couplings are disconnected.

4.

Push up to the adjustment position to release the adjuster until the cable housings separate.

5.

Depress the adjuster clip once. This mobilizes the adjuster housing toward the transaxle end fitting.

6.

Line up the end fittings so they slide together until you feel the parts cam together and lock.

7.

Depress the adjuster clip completely. This locks the cable into its adjusted service position.

8.

Pull the conduit in the opposite direction to assure full system adjustment of the shift cable.

Important: The horseshoe clip with the tab is flush when fully engaged.

9.

Ensure the conduit is fully engaged.

10.

The horseshoe clip with the tab is not flush when not fully engaged.

11.

Install the shift cable retainer and the wiring harness clip or wiring harness strap.

Park Lock Cable Adjustment

1.

Place the shift lever in the PARK position.

2.

Place the ignition key in the LOCK position.

3.

Ensure the shift lever cannot move to another position. The ignition key should be removable from the ignition lock cylinder.

4.

Place the ignition key in the RUN position.

5.

Place the shift lever in the NEUTRAL position.

6.

Ensure that the ignition key cannot turn to the LOCK position.

7.

The system is properly adjusted if the above conditions are met. Proceed to step 13.

8.

If the above conditions are not met proceed with the adjustment procedure.

9.

Pull the cable connector lock back to the UP position.

10.

Adjust the cable connector as outlined.

10.1

Push the cable connector nose forward to remove the slack.

10.2

Push the cable connector lock button down.

11.

Check the operation.

12.

If the ignition key cannot be removed in the PARK position, then pull the connector lock button to the UP position.

13.

Move the cable connector nose rearward until the key can be removed from the ignition.

14.

Push the lock button down.

15.

Install the cable into the clips to provide the correct routing.
