REMOVAL & INSTALLATION



  1. From the air cleaner, remove the air suction guide.
  2.  
  3. Disconnect both cables from the battery and the negative cable from the transaxle. Remove the battery and the battery tray.
  4.  
  5. From the transaxle, disconnect the solenoid coupler, the shift lever switch coupler and the wiring harness.
  6.  
  7. Separate the oil pressure control cable from the accelerator cable. From the transaxle, disconnect the accelerator cable and the shift selector cable.
  8.  
  9. Remove the starter motor. Place a catch pan under the transaxle and drain the fluid.
  10.  
  11. Disconnect and plug the oil cooler tubes at the transaxle.
  12.  
  13. Raise and support the vehicle safely. Remove the exhaust pipe and the lower clutch housing plate.
  14.  

Before removing the torque converter-to-drive plate bolts, make alignment marks on the torque converter and drive plate for assembly purposes.

  1. Using a prybar, insert it through the notch (underside of transaxle) to lock the drive plate gear. Remove the torque converter-to-drive plate bolts.
  2.  
  3. To remove the left halfshaft, perform the following procedures:
    1. From the wheel hub, remove the center cap, the split pin and the driveshaft nut.
    2.  
    3. Remove the lug nuts and the front wheels.
    4.  
    5. Using a prybar, position it between the differential case and the halfshaft's inboard joint, pry the joint until the snapring disconnects from the side gear.
    6.  
    7. Remove both stabilizer bar-to-chassis brackets and the ball stud-to-steering knuckle bolt. Pull the stabilizer bar downward to disconnect the ball joint from the steering knuckle.
    8.  
    9. Carefully remove the halfshaft from the differential case and the steering knuckle to prevent tearing the boots.
    10.  

  4.  
  5. Using a prybar, disconnect the right halfshaft from the differential case.
  6.  
  7. Remove the transaxle mounting member bolts and the member. Using a floor jack and a piece of wood, support the transaxle.
  8.  
  9. Remove the left transaxle mount.
  10.  
  11. Remove the transaxle-to-engine bolts. Slide the transaxle from the engine (to prevent damaging the crankshaft, drive plate or torque converter) and lower it from the vehicle.
  12.  

To install:
  1. Using grease, lubricate the cup around the center of the torque converter.
  2.  
  3. Measure the distance between the torque converter and the transaxle housing; it should be at least 0.85 in. (21.4mm). If the distance is less than specified, the torque converter is improperly installed; remove and reinstall it.
  4.  
  5. When installing the transaxle, guide the right halfshaft into the differential case; make sure the snapring seats in the differential gear.
  6.  
  7. To install the left halfshaft, perform the following procedures:
    1. Clean and lubricate the halfshaft splines with grease.
    2.  
    3. Carefully install the halfshaft into the steering knuckle and the differential case to prevent tearing the boots; make sure the snapring seats in the differential gear.
    4.  
    5. Install the ball joint stud into the steering knuckle and torque the bolt to 36-50 ft. lbs. (50-70 Nm).
    6.  
    7. Install the stabilizer bar-to-chassis brackets and torque the bolts to 22-39 ft. lbs. (30-55 Nm).
    8.  
    9. Torque the halfshaft hub nut to 108-195 ft. lbs. (150-270 Nm) and install the split pin (to the shaft) and the center cap.
    10.  
    11. Torque the lug nuts to 29-50 ft. lbs. (40-70 Nm).
    12.  

  8.  
  9. Torque the transaxle housing-to-engine bolts to 12-16.5 ft. lbs. (16-23 Nm), the mounting member-to-chassis bolts to 40 ft. lbs. (55 Nm), the mounting member-to-transaxle nuts to 33 ft. lbs. (45 Nm) and the transaxle-to-mount bolts to 40 ft. lbs. (55 Nm).
  10.  
  11. Using a prybar, insert it through the notch (underside of transaxle) to lock the drive plate gear and torque the torque converter-to-drive plate bolts to 13-14 ft. lbs. (18-19 Nm).
  12.  
  13. Install the oil cooler lines and the starter.
  14.  
  15. After connecting the oil pressure control cable to the accelerator cable, check and/or adjust the cable play.
  16.  
  17. Connect the wiring harness, the shift lever switch coupler and the solenoid coupler to the transaxle.
  18.  
  19. Install and adjust the select cable and shift switch.
  20.  
  21. Install the battery tray and the battery. Connect the battery cables to the battery and the negative battery cable to the transaxle.
  22.  
  23. Install the air suction guide to the air cleaner.
  24.  
  25. Refill and check the fluid level.
  26.
