  14.  
  15. Remove the bolts attaching the torque converter to the drive plate. Turn the flywheel as necessary to gain access to each of the bolts, which are spaced at equal intervals around it. Make sure to re-use the same bolts and retain the washers.
  16.  
  17. To remove the speed and reference mark sensors, remove the attaching bolt for each and remove each sensor. Keep the sensors clean.
  18.  
  19. Turn the bayonet type electrical connector counterclockwise and then pull the plug out of the socket. Then, lift the wiring harness out of the harness bails.
  20.  
  21. Support the transmission using the proper jack. Then, remove the crossmember that supports the transmission at the rear.
  22.  
  23. Disconnect the transmission shift rod. Then, remove the nuts and then the through bolts from the damper-type U-joint at the front of the transmission.
  24.  
  25. Unscrew the driveshaft spline locking ring at the center mount, if equipped, using the special tool designed for this purpose. Then, remove the bolts and remove the center mount. Bend the driveshaft downward and pull it off the centering pin. Suspend it with wire from the underside of the vehicle.
  26.  
  27. Lower the transmission as far as possible. Then, remove all the Torx® or standard type bolts attaching the transmission to the engine.
  28.  
  29. Remove the small grill from the bottom of the transmission. Then press the converter off with a large prybar passing through this opening while sliding the transmission out.
  30.  

To install:

  1. Install the transmission in position under the vehicle and raise it into position. Observe the following points:
    1. Make sure the converter is fully installed onto the transmission-so the ring on the front is inside the edge of the case. Only use M10x16mm bolts as originally equipped or damage will occur.
    2.  
    3. When reinstalling the driveshaft, tighten the lockring with the proper tool.
    4.  
    5. Make sure to replace the self-locking nuts on the driveshaft flexible joint and to hold the bolts still while tightening the nuts to keep from distorting it.
    6.  
    7. When installing the center mount, preload it forward from its most natural position 0.157-0.236 inches (4-6mm).
    8.  
    9. When reconnecting the bayonet type electrical connector, make sure the alignment marks are aligned after the plug it twisted into its final position.
    10.  
    11. When reinstalling the speed and reference mark sensors, inspect the O-rings used on the sensors and install new ones, if necessary. Make sure to install the speed sensor into the bore marked D and the reference mark sensor, which is marked with a ring, into the bore marked B.
    12.  
    13. Torque the crossmember mounting bolts to 16-17 ft. lbs. (21-23 Nm).
    14.  
    15. If O-rings are used with the transmission oil cooler connections, replace them.
    16.  
    17. Adjust the throttle cables.
