NOTE: Kent-Moore tool number "J8092", driver handle, weighs approximately 1.4 kilograms or three (3) pounds, may be a possible choice.

4. Verify that the transmission is in the "NEUTRAL" position.

5. Tighten screw, automatic transmission range selector rod swivel, (816) to 28 N.m (21 lb. ft.).

6. Inspect to ensure the steering column selector lever has not moved from the "N" (NEUTRAL) position.

7. Verify the transmission shift control system is properly adjusted.

a. With ignition key removed, while attempting to shift the steering column selector lever from "P" (PARK) into the "R" (REVERSE) position, verify the vehicle will not roll either by placing the vehicle on an incline or by pushing the vehicle.

NOTE: If the transmission shift control system is improperly adjusted, the column selector lever may NOT have to be completely out of the " P" (PARK) position in order for the vehicle to roll.

b. Verify the proper operation of steering column selector lever and transmission in all gear ranges.

If transmission control system is not functioning properly, repeat Steps 1 through 7.
