Transaxle Removal & Installation

Print

  1. Before servicing the vehicle, refer to the Precautions section.
  2.  
  3. Drain the transaxle fluid.
  4.  
  5. Remove or disconnect the following:

    Battery and bracket
     
    Air duct assembly
     
    Transaxle solenoid harness connector, Park Neutral Position (PNP) switch connector and revolution switch connector
     
    Crankshaft Position (CKP) sensor from the transaxle
     
    Control cable and transaxle coolant lines
     
    Halfshafts, the intake manifold support bracket and the starter
     
    Upper bolts attaching transaxle to the engine
     

  6.  
  7. Support the engine with a suitable stand and use a suitable jack to support the transaxle.
    NOTE
    Bolts are of different lengths, note the locations that the bolts are removed from.

    Rear cover plate and the bolts securing the torque converter to the driveplate. Rotate the crankshaft to gain access to the bolts
     
    Transaxle mounts
     
    Lower transaxle mounting bolts and lower the transaxle
     

  8.  

To install:

  1. Place a straightedge across the bell housing of the transaxle and measure the distance to the mounting bosses on the torque converter. The distance should be 0.626 in. (16mm). If not, the torque converter is not installed correctly.
  2.  
  3. Check the driveplate run-out with a dial indicator. Maximum allowable run-out is 0.008 in. (0.2mm).
  4.  
  5. Raise the transaxle into position and install the transaxle mounting bolts. Tighten the 50, 55, and 65mm long bolts to 51-59 ft. lbs. (70-79 Nm). Torque the 35 and 45 mm long bolts to 12-15 ft. lbs. (16-21 Nm).
  6.  
  7. Install or connect the following:

    Torque converter bolts. Torque the bolts to 33-43 ft. lbs. (44-59 Nm). Rotate the crankshaft to gain access to the bolts
     
    Rear cover and center member

    CKP sensor to the transaxle
     
    Transaxle solenoid harness connector, PNP switch connector and revolution switch connector
     
    Air duct assembly
     
    Battery and bracket
