Removal

Transmission

NOTICE: Whenever a transmission has been disassembled to install new parts, the transmission fluid cooler tubes must be cleaned and backflushed using suitable transmission fluid cooler tube backflushing and cleaning equipment. A new transmission fluid cooler must be installed.

When internal wear or damage has occurred in the transmission, metal particles, clutch plate material or band material may have been carried into the torque converter and transmission fluid cooler. These contaminants are a major cause of recurring transmission concerns and must be removed from the system before the transmission is returned to service.

NOTICE: After the transmission is removed for a major overhaul, it is important to clean all transmission components, including torque converter, cooler inlet tube, main control valve body, clutches and all coasting booster valve shuttle balls after any transmission service that generates contamination. These contaminants are a major cause for recurring transmission concerns and must be removed from the system before the transmission is returned to service.

The cleaning of foreign material from the direct clutch check ball is often omitted. This omission can lead to a repeat servicing of the transmission.

A new transmission fluid cooler must be installed under the following condition. For additional information, refer to Transaxle/Transmission Cooling Transmission Fluid Cooler.
- Evidence of broken transmission components or transmission fluid contamination found due to the following transmission or torque converter failure modes:
- Major metallic failure
- Multiple clutches or clutch plate failure
- Sufficient component wear which results in metallic contamination



1. Disconnect the battery ground cable. For additional information, refer to Battery, Mounting and Cables Battery Disconnect.

2. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Jacking and Lifting Service and Repair.

3. NOTE: Do not drain the transmission unless disassembly or installation of a new transmission is required. For additional information, refer to Fluid Pan, Gasket and Filter Service and Repair.

Drain the transmission fluid.

- Loosen the transmission fluid pan bolts and allow the transmission fluid to drain.

4. Install the transmission fluid pan and the old gasket.

1. Position the transmission fluid pan gasket.

2. Position the transmission fluid pan.





5. Remove the driveshaft. For additional information, refer to Driveshaft Removal and Replacement.

6. Remove the torque converter access cover plug at the left rear engine block.





7. Remove the torque converter access cover.

1. Remove the 2 bolts.

2. Remove the inspection cover.

3. Remove the bolt for the separator plate.





8. NOTE: Place an identifying mark on the torque converter stud and the flexplate for correct alignment during assembly.

Remove and discard the 4 torque converter-to-flexplate nuts.





9. Remove the exhaust system. For additional information, refer to Exhaust System [1][2]Diagrams.

10. Remove the selector lever cable from the manual control lever.





11. Remove the selector lever cable bracket and position aside.





12. Remove the ground wire.





13. Remove the starter electrical connector cap.





14. Disconnect the electrical connectors.





15. Remove the 3 starter bolts and the starter.





16. NOTE: The case connectors must be held in place to prevent them from moving.

Remove the transmission fluid cooler tubes.





17. Remove the transmission fluid cooler tube bracket and position aside.





18. Position a suitable jack under the transmission. Secure the transmission to the jack with safety straps.

19. Remove the transmission insulator and retainer nuts.





20. Remove transmission support crossmember. For additional information, refer to Transmission Support Crossmember Service and Repair.

21. Remove the transmission insulator and retainer bolts and the transmission insulator and retainer.





22. NOTE: It is not necessary to disconnect the transmission harness from all the transmission sensors at this time, the harness will come out with the transmission.

Disconnect the wire harness connectors and remove them from the transmission filler tube.





23. Remove the transmission filler bolt.





24. Position the transmission filler tube aside.





25. Remove the 6 transmission case bolts.





26. Separate and lower the transmission from the engine. Partially lower the transmission from under the vehicle.

27. Disconnect the electrical connectors.

1. Remove the catalyst monitor connector retainer from the stud.

2. Disconnect the transmission vehicle harness connector.





28. Disconnect the electrical connectors and remove the wire harness from the transmission.

1. Disconnect the TR sensor connector.

2. Disconnect the Output Shaft Speed (OSS) sensor connector.

3. Disconnect the Turbine Shaft Speed (TSS) sensor connector.

- Remove the catalyst monitor connector retainer from the stud.

- Disconnect the wire harness retainers and remove the harness.





29. Keep the transmission in a horizontal position, slide it back far enough to install the Torque Converter Retainer. Install the Torque Converter Retainer.





30. NOTE: Make sure the Torque Converter Retainer is in place and the transmission is securely fastened to the transmission jack before tilting the transmission.

Lower the transmission from under the vehicle.

31. If the transmission is being disassembled to install new parts, or if a new or remanufactured transmission is being installed, the transmission fluid cooler, the auxiliary transmission fluid cooler (if equipped) and the transmission fluid cooler tubes must be cleaned and backflushed to keep contaminants from entering the transmission. For additional information, refer to Transmission Fluid Cooler Tubes Backflushing and Cleaning Transmission Fluid Cooler Tubes Backflushing and Cleaning.
