Control Valve Body Disassemble

Control Valve Body Disassemble
^ Tools Required
- J 33163 Valve Tray Set

NOTICE:
^ Transmission damage may occur when control valve assembly springs and other parts are mistakenly interchanged. Interchanging parts can be avoided by observing the following precautions:
^ Tag each part as it is removed.
^ Use J 33163 Valve-Tray Set to organize parts and to simplify correct valve body reassembly.
^ Protect control valve assembly parts from damage by observing the following precautions:
^ Handle all valves carefully.
^ Protect control valve assembly parts during removal, cleaning, inspection, and reassembly.
^ Keep the parts in a clean container until the parts are installed.
^ When a valve is installed dry, the weight of the valve is sufficient to move the valve through the valve bore. If a valve does not move freely, the transmission may be damaged.





1. Position the control valve module on the work table so that the main valve body module is facing up.
2. Remove six bolts (1) and one bolt (2) retaining the reverse signal tube and pressure switch assembly to the main valve body.





3. Remove reverse signal tube (2) from main valve body (3).
4. Remove pressure switch assembly (1) from main valve body (3).





5. Remove two bolts (1) retaining the G solenoid valve body.
6. Remove G solenoid body (2 )assembly
7. Remove G solenoid retainer (5) from the bottom of the valve body.
8. Remove G solenoid (3 )
9. Remove two O-rings (4 ) from G solenoid (3 ).





10. Remove F trim solenoid retainer (1).
11. Remove F trim solenoid (7), sleeve (4), valve (3), and spring (2).
12. Remove O-rings (5 )and (6) from F trim solenoid (7 ).





13. Remove D ON/OFF shift solenoid retainer (1).
14. Remove D ON/OFF shift solenoid (4).
15. Remove O-rings (2) and (3) from D ON/OFF shift solenoid (4).





16. Remove E ON/OFF shift solenoid retainer (1).
17. Remove E ON/OFF shift solenoid (4).
18. Remove O-rings (2) and (3) from E ON/OFF shift solenoid (4).





19. Remove three bolts (1) that retain A/B solenoid bracket (2) to main valve body (3).





20. Remove A/B solenoid bracket (1), two accumulator springs (2), and two accumulator plugs (3).
21. Remove A trim solenoid (15), valve (13), spring (12), if present, valve (11), and spring (10).
22. Remove B trim solenoid (9), valve (7), valve (6), and spring (5).
23. Remove O-ring (14) from A trim solenoid (15).
24. Remove O-ring (8) from B trim solenoid (9).





25. Position the control valve module on the work table so that shift valve body (1) is facing up.
26. Remove C ON/OFF shift solenoid retainer (2).
27. Remove C ON/OFF shift solenoid (5).
28. Remove O-rings (3) and (4) from C ON/OFF shift solenoid (5).





29. Remove eleven bolts (1) retaining the shift valve body and the main valve body together.
30. Position the control valve module on the work table so that the main valve body is facing up. Reinstall four bolts (1) so that the bolts are partially threaded into the shift valve body and protrude from the main valve body.
31. Position the control valve module on edge so that the top and bottom are vertical.
32. Gently tap the bolts until the module separates.





33. Position the control valve assembly on the work table so that shift valve body (1) is facing up.
34. Separate shift valve body assembly (1), separator plate (2), and main valve body assembly (4).
