8. Remove the transmission fluid filler tube.
^ Remove the bolt and nut.





9. Disconnect the electrical harness connectors.





10. Remove the torque converter housing-to-engine retaining bolts. Position the fuel and electrical harness brackets aside.





11. NOTE: The case fittings must be held in place to prevent them from moving.

Disconnect the transmission fluid cooler tubes. Plug all fittings and position the transmission fluid cooler tubes aside.





12. NOTE: The output shaft and driveshaft are a balanced assembly.

Mark the driveshaft flange and the rear pinion flange for correct alignment during assembly.

20. Remove the flexplate inspection plate.
1) Remove the bolts.
2) Remove the flexplate inspection plate.
3) Remove the bolt.





21. Disconnect the catalyst monitoring sensor harness connectors.





22. Remove the bolts.





23. Secure the high lift transmission jack to the transmission.





24. Remove the crossmember.
1) Remove the crossmember-to-frame retaining nuts.
2) Remove the stud brackets.
3) Support the transmission support crossmember.
4) Remove the transmission insulator and retainer-to-crossmember retaining nuts and the transmission support crossmember.





25. Remove the bolts.





26. Remove the transmission from the vehicle.

^ CAUTION: Watch for clearance between the transmission and the right side heat shield, as well as other obstructions while lowering the transmission, or damage may occur.

Separate and back the transmission away from the engine, positioning the extension housing above the exhaust crossover pipe.





27. Disconnect the solenoid body connector.





28. Disconnect the electrical connectors and remove the wire harness from the transmission.
1) Disconnect the digital TR sensor electrical connector.
2) Disconnect the OSS sensor electrical connector.
3) Disconnect the TSS sensor electrical connector and remove the wire harness from the transmission.





29. Install the special tool.

^ WARNING: Secure the torque converter in the transmission during removal or installation. The torque converter is heavy and may result in injury if it falls out of the transmission. Failure to follow this instruction may result in serious personal injury.

CAUTION: Watch for clearance between the transmission and the engine, or damage may occur.

Carefully tilt the front of the transmission downward.

^ CAUTION: Watch for clearance between the transmission and the exhaust crossover pipe, or damage may occur.

Lower the transmission enough to clear the engine. Then, carefully pull the jack with the transmission toward the front of the vehicle, lowering the transmission as required until it is clear of the exhaust crossover pipe.
^ Tilt the front of the transmission upward until level.
^ Remove the transmission with the jack from under the vehicle.
