    1. Tighten bolts labeled No. 1 and 2 to 29-36 ft. lbs. (39-49 Nm).
    2.  
    3. Tighten all other bolts to 22-29 ft. lbs. (29-39 Nm).Bolts are of varying lengths. Install the bolts in their proper positions.

If the detents cannot be felt or the pointer indicator is improperly aligned while shifting from the P range to range 1 , the linkage should be adjusted.

If the vehicle has an automatic transmission interlock system, the system will prevent the transmission selector from being shifted from the P position unless the brake pedal is depressed.

  1. Place the shifter in the P position.
  2.  
  3. Loosen the locknuts.
  4.  
  5. Tighten the outer locknut X until it touches the trunnion, pulling the selector lever toward the R range side without pushing the button.
