Valve Body Replacement

Valve Body

The valve body can be removed for service without having to remove the entire transmission assembly.

The valve body can be disassembled for cleamng and inspection of the individual components. Refer to the procedures in the appropriate transmission overhaul section.

The only serviceable valve body components are the:
- manual lever
- manual lever washer/seallE-clip and shaft seal
- lever detent ball and spring
- throttle lever
- fluid filter
- switch valve, spring and adjusting screw bracket
- park rod and E-clip
- converter clutch solenoid
The remaining valve body components are serviced only as part of a complete valve body assembly.

Note: For Check Ball locations, refer to Valve Body/Component locations. Locations

Removal
1. Raise vehide.
2. Remove oil pan and drain fluid.
3. Loosen clamp bolts and remove throttle and manual valve levers from manual lever shaft.
4. Remove park/neutral position switch.
5. Remove filter from valve body.
6. Disconnect solenoid wire from case connector.
7. Remove valve body attaching screws.






8. Lower valve body enough to remove accumulator piston and piston spring (as shown).
9. Pull valve body forward to disengage park rod.
10. Push manual lever shaft and solenoid case connector out of transmission case.






11. Lower valve body, rotate it away from case, pull park lock rod out of sprag, and remove valve body (as shown).

Installation
1. Verify that park/neutral position switch has NOT been installed.
Valve body cannot be installed with switch in place.
Remove switch if necessary.
2. Install new seals on accumulator piston if necessary. and install piston in case.
Use small amount of petroleum jelly to hold piston in place.
3. Place valve body manual lever in low (1 position) to ease inserting park rod into sprag.
4. Use screwdriver to push park sprag into engagement with park gear.
This makes clearance for knob on lock rod to move past sprag when valve body is installed.
Rotate output shaft to verify sprag engagement.
5. Position accumulator spring between accumulator piston and valve body.
6. Position valve body on transmission and work knob on park lock rod past sprag.
Be sure accumulator piston and spring remain in position.
7. Hold valve body in position and install valve body attaching screws finger tight.
8. Install park/neutral position switch.
9. Tighten valve body attaching screws ALTERNATELY and EVENLY to 11 Nm (100 in. lbs.) torque.
10. Install new fluid filter on valve body.
Install and tighten filter screws to 4 Nm (35 in. lbs.) torque.
11. Connect solenoid wire to case connector.
12. Install manual lever and throttle lever on throttle lever shaft.
Tighten lever clamp screws and check for free operation.
Shaft and levers must operate freely without any bind.
13. Install oil pan and new gasket.
Tighten pan bolts to 17 Nm (150 in. lbs.) torque.
Install gasket dry; do not use sealer.
14. Connect park/neutral position switcb and converter clutch solenoid wires.
15. Install speedometer pinion gear, adapter and speed sensor.
16. Lower vehicle.
17. Fill transmission with MOPAR ATF+4, Type 9602 fluid.
