Control Valve Body Disassemble

Control Valve Body Disassemble (Disassembly of Control Valve Assembly)

Disassembly of Control Valve Assembly

^ Tools Required
- J 33163 Valve Tray Set





Important:
^ 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 Train 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 body assembly on the work table so that the main valve body assembly is facing up.
2. Remove the six bolts (1) and one bolt (2), holding 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 F trim solenoid retainer (1).
6. Remove F trim solenoid (7), sleeve (4), valve (3), and spring (2).





7. Remove D ON/OFF shift solenoid retainer (1).
8. Remove D ON/OFF shift solenoid (4).
9. Remove O-rings (2,3) from D ON/OFF shift solenoid (4).





10. Remove E ON/OFF shift solenoid retainer (1).
11. Remove E ON/OFF shift solenoid (4).
12. Remove O-rings (2,3) from E ON/OFF shift solenoid (4).





13. Remove three bolts (1) holding AID solenoid bracket (2) to main valve body (3).





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





Important: Do not damage the solenoid(s) when turning over the control valve assembly.

19. Position the control valve assembly on the work table so that shift valve body (1) is facing up.
20. Remove C ON/OFF shift solenoid retainer (2).
21. Remove C ON/OFF shift solenoid (5).
22. Remove O-rings (3,4) from C ON/OFF shift solenoid (5).





23. Position the control valve assembly on the work table so that the main valve body is facing up
24. Remove fourteen bolts (1) holding the shift valve body to the main valve body.
25. Position the control valve assembly on the work table so that the assembly is on edge (sideways).
26. Reinstall four bolts (1) so that the bolts are partially threaded into the shift valve body and protrude from the main valve body.
27. Gently tap on the bolts until the assembly separates.





28. Position the control valve assembly on the work table so that shift valve body (1) is facing up.
29. Remove shift valve body assembly (1) and separator plate (2).
