Manual Shift Linkage Adjust

Some General Motors units are equipped with anti-theft lock systems which lock not only the steering column but the transmission linkage as well. It is essential that this "back drive" linkage also be adjusted when any adjustment to the manual shift linkage is made. This adjustment must be precise as any inaccuracies may result in unit operation without controls in full detent which, in turn, will cause reduced oil pressure and subsequent failure of the transmission.

1. Loosen nut or screw on shift rod trunnion.

2. Pull trunnion lever upward to Park position, then downward to the third (Neutral) step.

3. Place steering column selector lever in Neutral position.

4. Tighten the shift rod trunnion nut or screw.

5. Check for proper operation.
