  6.  

To install:

When connecting the torque converter to the transaxle, be sure to measure the distance between the mounting lug of the converter and the front edge of the transaxle.

  1. The measured distance between the converter and the front of the transaxle should be:
    1. 0.831 in. (21.1mm) or more for GA16DE engine vehicles
    2.  
    3. 0.626 in. (15.9mm) or more for SR20DE engine vehicles


    4.  

  2.  
  3. Raise the transaxle and install to engine drive plate.
  4.  
  5. Install the transaxle mounting bolts in the proper location as noted during removal.
    1. On 1.6L engines torque the 2 bottom bolts to 12-15 ft. lbs. (16-21 Nm) and all other bolts to 22-30 ft. lbs. (30-40 Nm).
    2.  
    3. On 2.0L engines torque the 2 bottom bolts to 12-15 ft. lbs. (16-21 Nm) and all other bolts to 51-59 ft. lbs. (70-79 Nm).
    4.  

  6.  
  7. Install or connect the following:

    Torque converter to the drive plate and torque the bolts to 33-43 ft. lbs. (44-59 Nm)
     
    Rear transmission mount
     
    Rear transmission bracket
     
    Front and rear gussets and the rear engine plate
     
    Center member
     
    Starter and torque the bolts to 31 ft. lbs. (42 Nm)
     
    Intake manifold support bracket
     
    Both half shafts
     
    Control cable
