Main Control Valve Body 

3. Callouts
   1. 1: Check balls
   2. 2: Solenoid damper
5. NOTE: Remove the valves by tapping the valve body on the palm of the hand to slide the valves out of the bores or by threading a 4-mm bolt into the valves and pulling them out. If it is necessary to use a pick, use extreme caution to prevent damaging the valves or valve bores. If necessary, disassemble parts of the main control valve body in small groups. Arrange the parts as they are removed to avoid mixing similar pieces.

   Use the General Equipment: Flat Headed Screw Driver

   Use the General Equipment: Magnetic Socket

6. NOTE: Do not stone or polish any valves or damage to the valves can occur. If the valves do not move freely, install a new assembly.

   Clean the valves, springs and main control valve body.

7. For valve and spring locations.

   Refer to: MAIN CONTROL VALVE BODY  .

9. Callouts
   1. 1: Check balls
   2. 2: Solenoid damper
10. For disassembly and assembly of the solenoid body, refer to SOLENOID BODY  .

    Solenoid Body 

13. NOTE: If not previously done, separate the solenoid body from the valve body.
16. Compress the valve springs and remove the retainers with a magnet. Remove the individual valves and springs from the solenoid body by tapping it on the palm of the hand to slide the valves out of the bores.

    Use the General Equipment: Magnetic Socket

17. NOTE: Be careful not to bend or twist the transmission internal wiring harness frame or solenoid terminals when removing the transmission internal wiring harness frame or damage can occur.
18. NOTE: The solenoids are calibrated from the factory and are not all the same. Failure to mark the solenoids to the ports they were originally in can result in mixing the solenoids and cause damage to the transmission or a harsh shift.
19. Use the General Equipment: Long Nose Pliers
21. NOTE: Be careful not to wash the numbers from the solenoids or the solenoid body. Failure to install the solenoids in the ports they were originally in can result in damage to the transmission or a harsh shift.
    NOTE: Do not stone or polish any valves or damage to the valves can occur. If the valves do not move freely during assembly, install a new solenoid body.
22. Inspect the solenoid screens for debris that may restrict fluid flow through the screen.
23. NOTE: The solenoids are calibrated from the factory and are not all the same. Failure to install the solenoids in the ports they were originally in can result in damage to the transmission or a harsh shift.

    If new solenoid(s) are not being installed, position the solenoids in their corresponding solenoid body ports.

24. For information on component views and base part numbers.

    Refer to: MAIN CONTROL VALVE BODY  .

25. NOTE: If installing a new Variable Force Solenoid (VFS), determine the base part number of the solenoid(s). The TCC  solenoid, Shift Solenoid A (SSA) and Shift Solenoid C (SSC) are all normally low pressure solenoids. The Line Pressure Control (LPC) solenoid, Shift Solenoid B (SSB) and Shift Solenoid D (SSD) are all normally high pressure solenoids. Shift Solenoid E (SSE) is not a Variable Force Solenoid (VFS); it is an ON/OFF solenoid.

    Callouts

    1. 1: Line Pressure Control (LPC) solenoid (normally high) part number 7G383
    2. 2: Shift Solenoid C (SSC) (normally low) part number 7G136
    3. 3: TCC  solenoid (normally low) part number 7G136
    4. 4: Shift Solenoid E (SSE) (normally closed [OFF]) part number 7G484
    5. 5: Shift Solenoid A (SSA) (normally low) part number 7G136
    6. 6: Shift Solenoid B (SSB) (normally high) part number 7G383
    7. 7: hift Solenoid D (SSD) (normally high) part number 7G383
    8. 8: Solenoid body part number 7G391
26. NOTE: If installing new solenoids, note the color of the plastic nozzle and the large O-ring. High pressure solenoids, such as the Line Pressure Control (LPC) solenoid, Shift Solenoid B (SSB) and Shift Solenoid D (SSD), have black plastic nozzles and orange O-rings. Low pressure solenoids, such as the TCC  solenoid, Shift Solenoid A (SSA) and Shift Solenoid C (SSC), have brown plastic nozzles and green O-rings. The solenoids can only be replaced with the same color solenoid.
27. NOTE: Determine the part number suffix by checking the solenoid service band number etched on the side of the solenoid. The band number is next to the two-dimensional matrix barcode on the side of the solenoid and will be a 1, 2, 3, 4 or 5. Determine the part number suffix and match the new solenoid base part number and suffix with the old solenoid.

31. NOTE: Be careful not to bend or twist the transmission internal wiring harness frame or solenoid terminals when removing the transmission internal wiring harness frame or damage can occur.
32. Torque:  31 lb.in (3.5 Nm)
33. NOTE: If the valves do not move freely during assembly, install a new solenoid body. Failure to install a new solenoid body can result in a harsh shift or damage to the transmission.
