13. Remove the end cover, and then the clutch control valve accumulator valve, plug, reducing valve and springs.
REASSEMBLY
CAUTION: Clean all parts with ATF. Do not use shop towels during reassembly operation. Tighten all valve body screws to 4 - 5.5 Nm (3 - 4 ft.lbs.). Using torque set driver, etc., torque all screws evenly.
Upper Valve Body:
1. Install valves, springs and plugs shown in the valve body.
2. Then install front end plate or front end cover and tighten seven screws to specified torque.
Shift Valves:
3. Insert 2-3 shift plug and 1-2 shift valve into valve body, then install rear end cover by tightening four screws to specified torque.
Upper Valve Body:

Separating Plate:
11. Clean solenoid valve filter and install solenoid valve to plate.
12. Pull off guide pins from plate.
Transfer Plate:
13. Insert two Special Tools, Guide Pins, into guide pin holes in upper valve body. Using guide pins as a guide, install transfer plate or intermediate plate.
