Fig. Fig. 1: Removing the transaxle

The automatic transaxle can be removed with the engine installed in the car, but the transaxle and torque converter must be removed as an assembly. Otherwise, the drive plate, pump bushing or oil seal could be damaged. The drive plate will not support a load no weight should be allowed to rest on the drive plate as the unit is removed; it must be fully disconnected from the converter before the transaxle is shifted out of its normal position.

  1. Disconnect the negative battery cable.
  2.  
  3. Have someone apply the brakes and, with the car still resting on the wheels, loosen the hub nut and the wheel nuts.
  4.  
  5. Remove the axle end cotter pins and nut locks. Loosen the axle hub nuts.
  6.  
  7. Raise and support the vehicle safely high enough to work comfortably. Raise the vehicle just high enough to work under the vehicle and inside the engine compartment.
  8.  
  9. Remove both front wheel and tire assemblies.
  10.  
  11. Remove the axle nuts and spring washers.
  12.  
  13. Disconnect the throttle and shift linkage from the transaxle.
  14.  
  15. Put a drain pan underneath and then disconnect both the upper and lower oil cooler hoses. If the car has a lockup converter, unplug the electrical connector, which is located near the dipstick.
  16.  
  17. Install a suitable engine support fixture device.
  18.  
  19. Remove the upper bolts those that are accessible from above from the bell housing.
  20.  
  21. Remove both front wheel and tire assemblies.
  22.  
  23. Remove the left splash shield, and left engine mount from the transaxle.
  24.  
  25. Follow the procedures under "Halfshaft Removal and Installation'' in this section. Remove both halfshafts.
  26.  
  27. If working with the use of a lift, make sure the vehicle is properly placed on the lift. Raise the vehicle to standing level. If using a floor transmission jack, raise and support the vehicle safely, yet high enough to permit the removal of the transaxle.
  28.  
  29. Remove the dust cover from under the torque converter. Remove the access plug in the right splash shield to rotate the engine. Matchmark the torque converter and drive plate. Then, remove the torque converter mounting bolts, rotating the engine after each bolt is removed for access to the next one.
  30.  
  31. Disconnect the plug for the neutral safety/backup light switch.
  32.  
  33. Remove the engine mount bracket from the front crossmember.
  34.  
  35. Support the transaxle from underneath. It must be supported in a positive manner and without the weight resting on the pan; it should be supported by its corners.
  36.  
  37. Remove the front mount insulator through-bolts.
  38.  
  39. Remove the long through-bolt from the left hand engine mount.
  40.  
  41. Remove the starter. Then, remove any bell housing bolts that are still in position.
  42.  
  43. Pry the transaxle away from the engine to ensure that the torque converter will clear the drive plate. Lower the transaxle and remove it from the engine compartment.
  44.  

To install:
  1. To install the transaxle, first support the unit securely and raise it into precise alignment with the engine block. Then, move it toward the block. Make sure to align the lower bolt holes in the transaxle bell housing with those in the block.
  2.  
  3. Install the lower bell housing bolts and the starter. Bell housing bolts are torqued to 105 inch lbs. (12 Nm)
  4.  
  5. Turn the engine via the crankshaft pulley bolt as necessary to align the torque converter bolt holes with those in the drive plate. Make sure the matchmarks made prior to disassembly are aligned. Install each bolt and torque it to 40 ft. lbs. (54 Nm) on 1981-85 models, and 55 ft. lbs. (75 Nm) on 1986-88 models. Then, turn the crank for access to the next set of bolt holes and install the bolt in that position.
  6.  
  7. Install the long through-bolt into the left hand engine mount.
  8.  
  9. Install the front mount insulator through-bolts.
  10.  
  11. Remove the jack supporting the transaxle. Then, install the engine mount bracket onto the front crossmember.
  12.  
  13. Reconnect the electrical connector for the backup light/neutral safety switch.
  14.  
  15. Install the dust cover under the torque converter. Install the access plug in the right splash shield.
  16.  
  17. Install the driveshafts by reversing the removal procedure. Install the left side splash shield.
  18.  
  19. With the wheels remounted and the car back on the floor, install the remaining bell housing bolts and torque them to 105 inch lbs.
  20.  
  21. Remove the engine support fixture.
  22.  
  23. Connect both the upper and lower oil cooler hoses. If the car has a lockup converter, replug the electrical connector.
  24.  
  25. Reconnect the throttle and shift cables and adjust them.
  26.  
  27. Install the differential cover on those transaxles from which it was removed. Form a new gasket from RTV sealant when installing the cover. Fill the differential or combined transaxle and differential with the approved automatic transaxle fluid. Reconnect the battery.
  28.
