Check linkage adjustment by starting engine in PARK and NEUTRAL. Adjustment is acceptable if the engine starts in only these two positions. Adjustment is incorrect if the engine starts in one position but not both positions
If the engine starts in any other position, or if the engine will not start in any position, the park/neutral switch is probably faulty.
Check condition of the shift linkage (Linkage Adjustment Components). Do not attempt adjustment if any component is loose, worn, or bent. Replace any suspect components.
Replace the grommet securing the shift rod or torque rod in place if either rod was removed from the grommet. Remove the old grommet as necessary and use suitable pliers to install the new grommet.
