1. Position the selector lever in the OD position against the rearward stop. The shift lever must be held in the rearward position using a constant force of 3 lbs. (1.4 Kg) while the linkage is being adjusted.
2. Loosen the manual lever-to-control cable retaining nut.
3. Move the transaxle manual lever to the OD position, second detent from the most rearward position.
4. Tighten the retaining nut to 11-19 ft. lbs. (15-26 Nm).
5. Check the operation of the transaxle in each selector lever position. Make sure the park and neutral start switch are functioning properly.

1. Position the selector lever in the D position against the drive stop. The shift lever must be held in the D position while the linkage is being adjusted.
2. Loosen the transaxle manual lever-to-control cable adjustment trunnion bolt.
3. Move the transaxle manual lever to the D position, second detent from the most rearward position.
4. Tighten the adjustment trunnion bolt to 12-20 ft. lbs. (16-27 Nm).
5. Check the operation of the transaxle in each selector lever position. Make sure the neutral start switch functions properly in P and N and the back-up lights are on in R.

Transaxle downshift control is controlled through the throttle position switch on 1991-95 vehicles equipped with the electronic automatic overdrive transaxle.

See Figures 1 and 2

The Throttle Valve (TV) cable normally does not need adjustment. The cable should be adjusted only if one of the following components is removed for service or replacement:

• Main control assembly
• Throttle valve cable
• Throttle valve cable engine mounting bracket
• Throttle control lever link or lever assembly
• Engine throttle body
• Transaxle assembly

1. Connect the TV cable eye to the transaxle throttle control lever link, then attach the cable boot to the chain cover.
2. If equipped with the 3.0L engine, with the TV cable mounted in the engine bracket, make sure the threaded shank is fully retracted. To retract the shank, pull up on the spring rest with the index fingers and wiggle the top of the thread shank while pressing the shank through the spring with the thumbs.
3. If equipped with the 3.8L engine, the TV cable must be unclipped from the right intake manifold clip. To retract the shank, span the crack between the two 180 degree segments of the adjuster spring rest with a suitable tool. Compress the spring by pushing the rod toward the throttle body with the right hand. While the spring is compressed, push the threaded shank toward the spring with the index and middle fingers of the left hand. Do not pull on the cable sheath.

4. Attach the end of the TV cable to the throttle body.
5. If equipped with the 3.8L engine, rotate the throttle body primary lever by hand, the lever to which the TV-driving nailhead is attached, to the wide-open-throttle position. The white adjuster shank must be seen to advance. If not, look for cable sheath/foam hang-up on engine/body components. Attach the TV cable into the top position of the right intake manifold clip.

The threaded shank must show movement or "ratchet'' out of the grip jaws. If there is no movement, inspect the TV cable system for broken or disconnected components, then repeat the procedure.

The Throttle Valve (TV) Control Linkage System consists of a lever on the throttle body of the injection unit, linkage shaft assembly, mounting bracket assembly, control rod assembly, a control lever on the transaxle and a lever return spring.

The coupling lever follows the movement of throttle lever and has an adjustment screw that is used for setting TV linkage adjustment when a line pressure gauge is used. If a pressure gauge is not available, a manual adjustment can be made.

A number of shift troubles can occur if the throttle valve linkage is not in adjustment. Some are:

• Symptom: Excessively early and/or soft upshift with or without slip-bump feel. No forced downshift (kickdown) function at appropriate speeds.
• Cause: TV control linkage is set too short.
• Remedy: Adjust linkage.
• Symptom: Extremely delayed or harsh upshifts and harsh idle engagement.
• Cause: TV control linkage is set too long.
• Remedy: Adjust linkage.
• Symptom: Harsh idle engagement after the engine is warmed up. Shift clunk when throttle is backed off after full or heavy throttle acceleration. Harsh coasting downshifts (automatic 3-2, 2-1 shift in D range). Delayed upshift at light acceleration.
• Cause: Interference due to hoses, wires, etc. prevents return of TV control rod or TV linkage shaft. Excessive friction caused by binding grommets prevents the TV control linkage to return to its proper location.
• Remedy: Correct the interference area, check for bent or twisted rods, levers. or damaged grommets. Repair or replace whatever is necessary. Check and adjust linkage is necessary.
• Symptom: Erratic/delayed upshifts, possibly no kickdown, harsh engagement.
• Cause: Clamping bolt on trunnion at the upper end of the TV control rod is loose.
• Remedy: Reset TV control linkage.
• Symptom: No upshift and harsh engagements.
• Cause: TV control rod is disconnected or the linkage return spring is broken or disconnected.
• Remedy: Reconnect TV control rod, check and replace the connecting grommet if necessary, reconnect or replace the TV return spring.

The TV control linkage is adjusted at the sliding trunnion block.

1. Operate the engine until normal operating temperature is reached. Adjust the curb idle speed to specification.
2. After the curb idle speed has been set, shut off the engine. Make sure the choke is completely opened. Check the throttle lever to make sure it is against the hot engine curb idle stop.
3. Set the coupling lever adjustment screw at its approximate midrange. Make sure the TV linkage shaft assembly is fully seated upward into the coupling lever.

4. To adjust, loosen the bolt on the sliding block on the TV control rod a minimum of one turn. Clean any dirt or corrosion from the control rod, free-up the trunnion block so that it will slide freely on the control rod.
5. Rotate the transaxle TV control lever up using a finger and light force, to insure that the TV control lever is against its internal stop. With reducing the pressure on the control lever, tighten the bolt on the trunnion block.
6. Check the throttle lever to be sure it is still against the hot idle stop. If not, repeat the adjustment steps.

1. Position the selector lever in DRIVE against the rear stop.
2. Raise the car and support it safely on jackstands. Loosen the manual lever to control lever nut.
3. Move the transaxle lever to the Drive position, second detent from the rear most position. Tighten the attaching nut. Check the operation of the transaxle in each selector position. Readjust if necessary. Lower the car.

1. Position the selector lever in the OVERDRIVE position against the rearward stop.
2. If the vehicle is equipped with a floor shift selector the shift lever must be held in the rearward position using a constant force of about 3 lbs. as the linkage is being adjusted.
3. Loosen the manual lever to control cable retaining nut. Be sure that the transaxle lever is in the OVERDRIVE position. Tighten the retaining nut to 11-20 ft. lbs. (15-26 Nm).
4. Check operation of the transaxle in each range. Be sure that the park switch and neutral safety switch are working properly.
