7. Remove the bolt and the shift lever switch (1).
8. Remove the bolt and the turbine sensor (1).
9. Remove the bolt and the vehicle speed sensor (1).

Note:

• | Remove any residual sealant from the housing and case surfaces.

• | Ensure that all sealant has been removed.

10. With the converter housing facing (1) upward, remove the installation bolts. Then remove the housing, tapping it lightly with a plastic hammer.
11. Remove the differential assembly (1).

Note: When removing the oil pump, be careful not to drop the input shaft.

Note: For a transmission with lock-up function, be careful not to damage the O-ring between the input shaft and the torque converter.

12. Remove the O-ring of the input shaft, and then remove the bolts and the oil pump (2).
13. Remove the reduction gear (1).
14. Remove the stopper bolt, the parking pawl (4), pawl spring (3), the pawl shaft, and the pawl collar.
15. Remove the bolts and the support actuator (1).

Note: Do not separate the stiffener from the pan with a screwdriver.

Note: Ensure that all sealant has been removed.

16. Remove the oil pan (1) installation bolts with the pan facing upward. Then, remove the stiffener (2) and the pan, tapping lightly with a plastic hammer.
17. Remove any residual sealant from the pan and case surfaces.
18. Remove the magnets from the oil pan.
19. Remove the connector from each solenoid (2).
20. Remove the bolts which secure the oil temperature sensor (1) to the ground, and remove the control valve installation bolts. Then, remove the valve (3).

Note: Do not pull on the harness when removing the connector.

21. While pushing the tabs (2), pull the solenoid connector (1) out from the case.
22. Remove the nut while holding the width across flats of the manual shaft (1), then remove the manual plate (2).
23. Remove the manual shaft lock bolt (2), and pull out the manual shaft (1).
24. Remove the E-ring (1), then remove the parking lever and the parking rod as a unit.

Note: Remove the O-rings from the end and face of the case.

Note: Ensure that all sealant has been removed.

25. Remove the side cover installation (1) bolts with facing upward, and then remove the covers.
26. Do not separate the side cover from the case with a screwdriver.
27. Remove any residual sealant from the surfaces of the side cover and case completely.

Note: To prevent the case from being scratched when removing the snap ring with a screwdriver, smooth the surface of the case with sandpaper. (This also prevents the O-ring from being scratched when re-assembling.)

28. Remove the snap ring with a flat head screwdriver, and pull the band servo cover (1) out with a pair of pliers.

Note: Temporarily tighten the lock nut to prevent the air vent pin from coming out.

29. Hold the piston stem (1), and loosen the locknut.
30. Loosen the piston stem.
31. Remove the reverse clutch drum (1).

Note: To prevent cracking when expanding the brake band, bind it with wire.

32. Remove the brake.
33. Remove the anchor end pin (2).

Note: Be careful not to drop the bearings from the both sides of high clutch assembly.

34. Remove the high clutch assembly (1).
35. Remove the high clutch hub (1).

Note: Be careful not to drop bearings from the side cover side and the bearing race on the torque converter side of the front sun gear assembly.

36. Remove the front sun gear assembly (1).
37. Using DT 47523 (1) and DT 47522 (2), remove the snap ring (3) from the band servo piston.

Note: The band servo piston may spring out because of the piston spring force. Be careful not to drop the piston.

38. Lightly tap the piston stem (1) with a plastic hammer, and remove the band servo piston with the reaction force of the piston spring.

Note: Be careful not to drop the bearing from the side cover side and the race-combined bearing from the torque converter side of the front carrier.

39. Remove the snap ring; then remove the front carrier (1) and the low 1-way clutch as a unit.
40. Remove the rear sun gear (1).

Note: Be careful not to drop the bearing from the side cover side and the race-combined bearing from the torque converter side of the rear carrier assembly.
