DISASSEMBLE
1. Remove and discard valve body gasket, then loosen and remove 11 bolts from reinforcement plates.

Detent Spring Guide Bolt Location:

2. Remove detent 5 ring 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, noting location of orange ball, as it is not interchangeable with other balls.

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, in the Valve Body images, noting the following:
a. Some bore plugs have threaded hole in center to facilitate removal by using M4 metric screw. These pugs 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.

ASSEMBLE
1. Assemble valve body components as shown, in the Valve Body images.
2. Install seven check balls as shown in the Location Of Relief Valves And Check Balls image. Orange ball is larger than the others and must be positioned as shown.
3. Install pressure relief valves.

Installing Alignment Pins In Valve Body:

4. Install alignment pins T80L-7710-A, or equivalents, as shown in the Installing Alignment Pins In Valve Body 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 80-100 in lbs.
