The front (kickdown) band adjusting screw is located on the left side of the transmission case above the manual and throttle valve levers.

  1. Raise the vehicle.
  2.  
  3. Loosen the band adjusting screw locknut, and then back off locknut 3-5 turns. Be sure the adjusting screw turns freely in the case. Lubricate the screw threads if necessary.
  4.  
  5. Tighten the band adjusting screw to 72 in. lbs. (8 Nm).
  6.  


CAUTION
Torque is critical. If an extension is used on the torque wrench to reach the adjusting screw, adjust the torque to 50 in. lbs. (5 Nm).

  1. Back off the front band adjusting screw by the following amounts:

    42RE: 3 5 / 8 turns
     
    44RE: 2 1 / 4 turns
     
    46RE: 2 7 / 8 turns
     
    47RE: 1 7 / 8

Shift Linkage



Apply a small amount of clean engine oil to the kickdown and shift linkage points at 7,500 mile (12,000 km) intervals.

The following procedure applies to automatic transmission-equipped models fitted with a shift linkage. For cable-operated models, see below.

  1. Check the linkage adjustment by starting engine in PARK and NEUTRAL .
  2.  
  3. Engine must start in both positions, but no other.
  4.  
  5. If performance is not correct, the park/neutral switch is probably at fault.
  6.  
  7. Check linkage and replace any worn or bent component. Do NOT attempt adjustment if any components are loose, worn or damaged. Tighten all fasteners before attempting adjustment.
  8.  
  9. 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.
  10.  
  11. Shift the transmission into PARK .
  12.  
  13. Raise the vehicle and support it safely.
  14.  
  15. Loosen the lockbolt in the front shift rod adjusting swivel.
  16.  
  17. Ensure that the shift rod slides freely in the swivel. Lubricate the parts as necessary.
  18.  
  19. Move the shift lever fully rearward to the PARK detent.
  20.  
  21. Center the adjusting swivel on the shift rod.
  22.  
  23. Tighten the swivel lockbolt to 90 inch lbs. (10 Nm).
  24.  
  25. Verify the gearshift and linkage operation.
  26.

The following procedure applies to automatic transmission-equipped models fitted with a shift linkage. For cable-operated models, see below.

  1. Check linkage adjustment by starting engine in PARK and NEUTRAL .
  2.  
  3. Engine must start in both positions, but no other.
  4.  
  5. If performance is not correct, the park/neutral switch is probably at fault.
  6.  
  7. Shift the transmission into PARK .
  8.  
  9. Release the cable adjuster locknut (underneath the power brake booster) to unlock the cable.
  10.  
  11. Raise the vehicle and support it safely.
  12.  
  13. Slide the cable eyelet off the transmission shift lever.
  14.  
  15. Verify the transmission shift lever is in the PARK detent by moving the lever fully rearward to the last detent position.
  16.  
  17. Verify the positive engagement of the transmission park lock by attempting to rotate the driveshaft. The shaft will not rotate when the park lock is engaged.
  18.  
  19. Slide the cable eyelet onto the transmission shift lever.
  20.  
  21. Lower the engine and check engine starting, which should be in PARK and NEUTRAL only.
  22.  
  23. Lock the shift cable by pressing the cable adjuster clamp down until it snaps into place.
  24.

Throttle Linkage



  1. Turn the ignition switch OFF and shift into PARK .
  2.  
  3. Remove the air cleaner.
  4.  
  5. Disconnect the cable end from the attachment stud on the throttle body. Carefully slide the cable off the stud. Do NOT pull or pry the cable off.
  6.  
  7. Verify that the transmission throttle lever is in the idle (full forward) position. The n be sure the lever on the throttle body is at curb idle position.
  8.  
  9. Insert a small screwdriver under the edge of the retaining clip and remove the retraining clip.
  10.  
  11. Center the cable end on attachment stud to within 0.04 in. (1mm).
  12.  


NOTE
Be sure that as the cable is pulled forward and centered on the throttle lever stud, the cable housing moves smoothly with the cable. Due to the angle at which the cable housing enters the spring housing, the cable housing may bind slightly and create an incorrect adjustment.

  1. In stall the retaining clip onto the cable housing.
  2.  
  3. Check the cable adjustment. Be sure the transmission throttle lever and lever on the throttle body move simultaneously and as described in the cable adjustment checking procedure.
  4.
