DISASSEMBLY

Position the valve body on a clean work surface to avoid contamination.

CAUTION: Do not clamp any part of the valve body assembly (Fig. 93) in a vise. This practice will distort the valve body and transfer plate resulting in valve bind. Slide valves and plugs out carefully. Do not use force at any time. The valves and valve body will be damaged if force is used. Also tag or mark the valve body springs for reference as they are removed. Do not allow them to become intermixed.

(1) Remove screws attaching adjusting screw bracket to valve body and transfer plate. Hold bracket firmly against spring force while removing last screw.

(2) Remove adjusting screw bracket, line pressure adjusting screw (Fig. 94).

(3) Remove switch valve and spring, pressure regulator valve and spring, kickdown valve and spring, and throttle valve from valve body (Fig. 94).

(4) Secure detent ball and spring in housing with Retainer Tool 6583 (Fig. 95).

(5) Remove manual shaft E-clip, washer, and seal (Fig. 96).

(6) Pull manual shaft and park rod assembly upward out of valve body and off throttle lever (Fig.

96).

(7) Remove manual valve from valve body (Fig. 97) (8) Remove Retainer Tool 6583. Then remove and retain detent ball and spring (Fig. 96).

(9) Remove throttle lever (Fig. 96).

(15) Turn valve body over so transfer plate is facing upward (Fig. 102). With valve body in this position, valve body check balls will remain in place and not fall out when transfer plate is removed.

(16) Remove screws attaching transfer plate to valve body (Fig. 102).

(17) Remove transfer plate and separator plate from valve body (Fig. 102). Note position of filter and clutch solenoid for reference. Remove valve body check balls.

(18) Position transfer plate on bench so separator plate, and filter are facing up. This will avoid having rear clutch and rear servo check balls fall out when plates are separated.
