Shift Interlock: Service and Repair

NOTE: The following procedure applies to vehicles with steering column mounted shift levers only.

REMOVAL

Fig. 66:

1. Remove the fuse panel cover from the left end of the instrument panel (Fig. 66).

Fig. 67:

2. Remove the two screws behind the fuse panel cover attaching the lower instrument panel cover to the instrument panel (Fig. 67).
3. Remove the lower instrument panel cover. The lower instrument panel cover is attached by retaining clips along the top and right edge.

NOTE: The upper shroud on this steering column is retained to the steering column by a snap fit to the lower shroud. When removing the upper shroud from the steering column lower shroud, DO NOT use a hard or sharp tool. This will damage the shrouds. If a tool must be used, use a soft tool such as a trim stick.

4. Remove the steering column upper shroud from the steering column using the following procedure: First, on the right seam between the upper and lower shrouds, push in on seam at the forward end. When the upper shroud unsnaps, pull the upper shroud upward away from the lower. Repeat this procedure on the opposite side of the column to release the upper shroud from the lower. Remove the upper shroud from the steering column.

5. Remove the tilt lever (Fig. 68) from the steering column.

6. Remove the 2 screws attaching the lower shroud to the steering column (Fig. 69). Remove the lower shroud from the steering column.

7. Disconnect the wiring harness connector from the Brake Transmission Shift Interlock (BTSI) solenoid (Fig. 70).

Fig. 71:

8. Remove the retainer clip from the end of the BTSI solenoid (Fig. 71).
9. Slide the BTSI solenoid straight off the shift lever mounting stud.

INSTALLATION

Fig. 72:

1. Align the flat inside the Brake Transmission Shift Interlock (BTSI) solenoid (Fig. 72) with the flat on the shift lever mounting stud.

Fig. 73:

2. Slide the solenoid completely onto the shift lever mounting stud aligning the plastic guide formed into the solenoid housing with the flange on the shift lever mechanism bracket (Fig. 73).

Fig. 74:

3. Install the retainer clip until it snaps into place in the slot cut into the shift lever mounting stud (Fig. 74).
4. Verify the BTSI solenoid is locked in place and will not slide off the mounting stud.
5. Connect the wiring harness connector to the BTSI solenoid.
6. Verify the BTSI is operating properly. With the ignition on (engine not running) and the parking brake applied, try shifting the transmission shift lever out of the PARK position with and without the brake pedal being applied. The shift lever should only shift out of PARK with the brake pedal being depressed.
7. Install the lower shroud (Fig. 69) on the steering column. Install and securely tighten the 2 screws attaching the lower shroud to the steering column.
8. Install the tilt lever (Fig. 68) on the steering column.
9. Install the upper shroud on the steering column by snapping it onto the lower shroud.
10. Install the lower instrument panel cover.
11. Install the two screws behind the fuse panel cover attaching the lower instrument panel cover to the instrument panel (Fig. 67).
12. Install the fuse panel cover on the left end of the instrument panel (Fig. 66).
