Special Tool(s)

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 transmission fluid pan and transmission fluid pan gasket.
1 Remove the bolts.
2 Remove the 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 alter, 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 plastic 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 inter-connector.

7. Remove the Output Shaft Speed (OSS) sensor.
1 Remove the bolt.
2 Remove the OSS sensor.

8. CAUTION: Discard the manual lever shaft outer nut. Do not reuse.

Remove the outer manual control lever.
1 Remove the manual lever shaft outer nut.
2 Remove the outer manual control lever.

9. Remove the digital Transmission Range (TR) sensor.
1 Remove the bolts.
2 Remove the digital TR sensor.

10. Remove the manual control valve detent lever spring.
