DISASSEMBLY
1. Remove and discard valve body gasket, then loosen and remove it bolts from reinforcement plates.

Detent Spring Guide Bolt Location:

2. Remove detent spring guide bolt from separator plate.

Location Of Separator Plate, Reinforcement Plates, And Separator Plate Gasket:

3. Remove separator plate, reinforcement plates, and separator plate gasket, discarding gasket.

Location Of Relief Valves And Check Balls:

4. Remove two relief valves and seven check balls from valve body.

NOTE: Note location of orange ball, as it is not interchangeable with other balls.

Removing Or Installing Throttle System Valves:

Removing Or Installing 2-3 Backout Valve:

Removing Or Installing Orifice Control And 2-3 Capacity Modulator Valves:

Removing Or Installing 3-4 Shift And 3-4 TV Modulator Valves:

Removing Or Installing TV Limit Valve:

Removing Or Installing 1-2 Shift Valve:

Removing Or Installing Overdrive Servo Regulator Valve:

Removing Or Installing 3-4 Shuttle Valve:

Removing Or Installing 1-2 Accumulator Valve:

Removing Or Installing 1-2 Capacity Modulator Valve:

Removing Or Installing Main Regulator And Pressure Boost Valves:

Removing Or Installing 2-1 Scheduling And Low Servo Modulator Valves:

Removing Or Installing 3-4 Backout Valve:

Removing Or Installing 2-3 Shift, 3-2 Control, And 2-3 TV Modulator Valves:

5. Complete disassembly of valve body as shown, noting the following:
a. Some bore plugs have threaded hole in center to facilitate removal by using M4 metric screw. These plugs must be installed with hole facing out.
b. The 1-2 accumulator valve and valve body diameter are not the same for all models.
c. Components may vary in size or shape for different applications.

ASSEMBLY
1. Assemble valve body components.
2. Install seven check balls.

NOTE: Orange ball is larger than others and must be positioned as shown in the Location Of Relief Valves & Check Balls image.
3. Install pressure relief valves.

Valve Body Alignment Pin Installation:

4. Install alignment pins T8OL-77100-A or equivalents, as shown in the Valve Body Alignment Pin Installation image. These two holes are smaller than other bolt holes to ensure proper alignment of gasket and separator plate with valve body. These two holes also align the valve body gasket and valve body assembly with the case.
5. Using new separator plate gasket, slide gasket and separator plate over the two alignment pins, then position three reinforcement plates and loosely install the 11 attaching bolts and the detent spring guide bolt.
6. Starting at center reinforcement plate and working outward, torque 11 attaching bolts, then the detent spring guide bolt, to 8O-100 in lbs.
