Secondary Valve Body Replacement

Secondary Valve Body Replacement

1. Do the battery removal procedure Removal and Replacement.

2. Remove the air cleaner Service and Repair.

3. Remove the intake air duct.

4. Remove the battery heat shield.

5. Remove the auxiliary under-hood fuse/relay box.

6. Remove the battery base.

7. Remove the ATF dipstick and the starter.

8. Disconnect these connectors:

- Shift solenoid valve A connector (A)
- Shift solenoid valve B connector (B)
- Shift solenoid valve C connector (C)
- Line pressure solenoid valve A connector (D)





9. Remove the harness clamps (E).

10. Disconnect these connectors:

- A/T clutch pressure control solenoid valve A connector (A)
- A/T clutch pressure control solenoid valve B connector (B)
- A/T clutch pressure control solenoid valve C connector (C)
- A/T clutch pressure control solenoid valve D connector (D)
- Transmission fluid pressure switch B (3rd clutch) connector (E)
- Transmission fluid pressure switch E (6th clutch) connector (F)
- Line pressure switch connector (G)
- Transmission range switch connector (H)





11. Remove the bolt (I) securing the harness cover (J), and remove the harness clamp (K).

12. Remove the harness cover bracket (A).






13. Raise the vehicle on a lift, and make sure it is supported securely.

14. Remove the engine undercover (A) and the front splash shield (B).






15. Disconnect the ATF temperature sensor connector (A), then remove the harness clamps (B).






16. Disconnect the transmission fluid pressure switch C (4th clutch) connector (A), then remove the harness clamp (B).






17. Disconnect the input shaft (mainshaft) speed sensor connector (A) and the output shaft (countershaft) speed sensor connector (B), then remove the harness clamps (C).






18. Remove the harness clamp (A), then remove the ATF dipstick guide tube (B) with the O-ring (C).






19. Remove the secondary valve body (A) and the gasket (B). Remove the ATF pipes (C).

NOTE: There are 11 ATF pipes. Do not drop the ATF pipes into the transmission. If an ATF pipe is dropped into the transmission, the transmission will need to be disassembled.





20. Replace the secondary valve body.

21. Clean the mounting surfaces of the transmission housing. Do not allow dust or other foreign particles to enter the transmission.

22. Apply ATF to new O-rings (A), and install the O-rings over the ATF pipes (B). Then install the ATF pipes with the filter ends (C) facing the secondary valve body (D) into the transmission.





23. Install a new gasket (E) to the transmission housing.

24. Install the secondary valve body while aligning the ATF pipes with the pipe holes on the secondary valve body, and secure the secondary valve body with the bolts.

25. Install the dipstick guide tube (A) with a new O-ring (B), and install the harness clamp (C).






26. Install the harness cover bracket (A).






27. Install the bolt (A) securing the harness cover (B), and install the harness clamp (C).





28. Connect these connectors:

- A/T clutch pressure control solenoid valve A connector (D)
- A/T clutch pressure control solenoid valve B connector (E)
- A/T clutch pressure control solenoid valve C connector (F)
- A/T clutch pressure control solenoid valve D connector (G)
- Transmission fluid pressure switch B (3rd clutch) connector (H)
- Transmission fluid pressure switch E (6th clutch) connector (I)
- Line pressure switch connector (J)
- Transmission range switch connector (K)

29. Install the harness clamps (A).





30. Connect these connectors:

- Shift solenoid valve A connector (B)
- Shift solenoid valve B connector (C)
- Shift solenoid valve C connector (D)
- Line pressure solenoid valve A connector (E)

31. Connect the input shaft (mainshaft) speed sensor connector (A) and the output shaft (countershaft) speed sensor connector (B), and install the harness clamps (C).






32. Connect the transmission fluid pressure switch C (4th clutch) connector (A), and install the harness clamp (B).






33. Connect the ATF temperature sensor connector (A), and install the harness clamps (B).






34. Install the front splash shield and the engine undercover.

35. Install the starter.

36. Install the ATF dipstick.

37. Install the battery base.

38. Install the auxiliary under-hood fuse/relay box.

39. Install the battery heat shield.

40. Install the intake air duct.

41. Install the air cleaner Service and Repair.
