Special Tool(s) (Part 2):





Disassembly (Steps 1-26)
1. Using the special tools, remove torque converter.





2. Using the special tool, mount the transmission to the bench.





3. NOTE: If the transmission fluid pan gasket is not damaged, it may be reused.

Remove the bolts, transmission fluid pan and transmission fluid pan-to-case gasket.





4. Clean the transmission fluid pan and pan magnet.





5. CAUTION: If installing a new filter and grommet remains in the main control bore, carefully use a small screwdriver to remove the grommet. Use care not to damage the main control bore.

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

Remove the fluid filter and grommet.





6. CAUTION: Do not pull on the molded lead frame. This may cause damage to the connector ends. Carefully pry up on the locking tabs to disconnect the solenoids. Disconnect the molded lead frame from the solenoids.

Disconnect the molded lead frame from the solenoids.
1 Disconnect the shift solenoid SSA and SSB.
2 Disconnect the torque converter clutch (TCC).
3 Disconnect the electronic pressure control (EPC) solenoid.
4 Disconnect the bulkhead interconnector.





7. Remove the output shaft speed (OSS) sensor and the turbine shaft speed (TSS) sensor.
1 Remove the OSS sensor bolt.
2 Remove the OSS sensor.
3 Remove the TSS sensor bolt.
4 Remove the TSS sensor.





8. Remove the digital transmission range (TR) sensor.
1 Remove the bolts.
2 Remove the digital TR sensor.





9. Remove the manual control valve detent lever spring.
^ Remove the bolt.





10. Remove the 23 main control valve body bolts and the main control valve body.





11. Remove and discard the pump outlet screen.





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

Remove the manual lever shaft retaining pin.





13. Remove the manual lever shaft inner nut.
^ Slide the manual control lever shaft out of the case while removing the inner nut.





14. Remove the parking lever actuating rod.
1 Remove the manual valve detent.
2 Remove the parking lever actuating rod.





15. CAUTION: 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.





16. Remove the EPC solenoid.
1 Remove the bolt and EPC solenoid bracket.
2 Remove the EPC solenoid.





17. Remove the 2-3 accumulator spring retainer.





18. Remove the 2-3 accumulator piston.
1 Remove the 2-3 accumulator spring.
2 Remove the 2-3 accumulator piston.





19. Using the special tool, remove the reverse band servo retaining ring.





20. Remove the reverse servo assembly.
1 Remove the reverse band servo cover.
2 Remove the reverse band servo piston and rod.
3 Remove the reverse band servo spring.





21. NOTE: If tool is not available, extreme care must be taken. Spring pressure will force overdrive servo piston assembly out of case. Case bore damage may result from trying to pry on internal retaining ring.

Using the special tool, compress the piston spring, then remove the overdrive servo piston retainer.





22. Remove the overdrive servo piston.
1 Remove the overdrive servo piston.
2 Remove the overdrive servo piston return spring.





23. Compress the 1-2 accumulator cover and remove the retaining ring.

1 Remove the 1-2 accumulator spring cover.
2 Remove the inner and outer lower 1-2 accumulator spring.
3 Remove the 1-2 accumulator.
4 Remove the 1-2 accumulator upper spring.





25. Using the special tools, remove the extension housing seal.





26. 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 4 bolts and 2 nuts.
2 Remove the extension housing and the extension housing gasket.
