5. Clean the transmission fluid pan and pan magnet.





6. NOTICE: If installing a new transmission fluid filter and the seal remains in the main control bore, use a small screwdriver and carefully remove the seal. Use care not to damage the main control bore.

NOTE: If the transmission is being repaired for a contamination-related failure, use a new transmission fluid filter and seal. The transmission fluid filter can be reused if no excessive contamination is present.

Remove the transmission fluid filter and seal.





7. Disconnect the transmission internal harness from the solenoids.

1. Disconnect Shift Solenoid A (SSA) and Shift Solenoid B (SSB).

2. Disconnect the Torque Converter Clutch (TCC).

1. Remove the OSS sensor bolt.

2. Remove the OSS sensor.

3. Remove the TSS sensor bolt.

4. Remove the TSS sensor.





9. NOTE: Discard the outer manual control lever shaft nut. Do not reuse. The old nut will not retain the proper torque specification.

Remove the outer manual control lever.

1. Remove and discard the manual control lever nut.

2. Remove the outer manual control lever.





10. Remove the Transmission Range (TR) sensor.

1. Remove the bolts.

14. Remove and discard the pump outlet screen.





15. NOTE: Use a shop cloth to protect the transmission case surface.

Remove the manual control lever shaft retaining pin.





16. Remove the manual control lever shaft inner nut.
- Slide the manual control lever shaft out of the case while removing the inner nut.





17. Remove the manual control valve detent lever and parking lever actuating rod.





18. NOTICE: Use care not to damage the manual control lever shaft bore. If the bore is damaged, the new seal may leak.

Remove the manual control lever shaft seal.





19. Remove the EPC solenoid.





20. Remove the 2-3 accumulator spring retainer.





21. Remove the 2-3 accumulator piston.

1. Remove the 2-3 accumulator spring.

2. Remove the 2-3 accumulator piston.

23. Remove the reverse band servo.

1. Remove the reverse band servo cover.

2. Remove the reverse band servo piston and rod assembly.

3. Remove the reverse band servo spring.





24. NOTICE: If the tool is not available, extreme care must be taken. Spring pressure will force the Overdrive (O/D) servo piston assembly out of the case. Case bore damage may result from trying to pry on the internal retaining ring.

Using the Servo Piston Remover/Installer, compress the piston spring, then remove the Overdrive (O/D) servo piston retainer.





25. Remove the O/D servo piston.

1. Remove the O/D servo piston.

2. Remove the O/D servo piston return spring.

1. Remove the 1-2 accumulator spring cover.

2. Remove the inner and outer 1-2 accumulator springs.

3. Remove the 1-2 accumulator.

4. Remove the 1-2 accumulator upper spring.





Rear Wheel Drive (RWD)

28. Using the Transmission Fluid Seal Remover and Slide Hammer, remove the extension housing seal.





29. NOTE: These bolts have been coated with a sealant. High break torque may be required to remove these bolts.

Remove the extension housing.

1. Remove the 6 bolts.

2. Remove the extension housing and the extension housing gasket.





Four-Wheel Drive (4WD)

30. Using the Input Shaft Oil Seal Remover and Slide Hammer, remove the extension housing seal.





31. NOTE: These bolts have been coated with a sealant. High break torque may be required to remove these bolts.

Remove the 6 extension housing bolts.





32. Remove the extension housing and gasket.





All transmissions

33. Remove the park pawl.

1. Remove the park pawl shaft.

2. Remove the park pawl return spring.

3. Remove the park pawl.





34. Rotate the transmission to the vertical position with the output shaft toward the floor.

35. NOTICE: Extreme care must be taken during transmission connector removal. Do not pull on wires or use a hammer on the connector body.

Place a screwdriver on the flat portion of the connector and push the connector out through the bottom of the case.





36. Using the Torque Converter Fluid Seal Remover and Slide Hammer, remove the front pump seal.





37. NOTE: These bolts have been coated with sealant. High break torque may be required to remove the bolts.

Remove the front pump support bolts.





38. Using the Transmission Fluid Pump Remover and Slide Hammer, remove the front pump support.





39. Remove and discard the pump gasket.
