DISASSEMBLY

CAUTION: All parts must be handled carefully to avoid nicking or burring the bearing or mating surfaces. Lubricate all internal parts with clean automatic transmission fluid before assembling them. Do not use any other lubricants except on gaskets and thrust washers. These may be coated with petroleum jelly to facilitate assembly. Always use new gaskets and seals when assembling transmission.

1.Remove screen from lower valve body.
2.Separate upper and lower valve bodies, and remove separator plate and gasket.
3.Remove manual valve retaining pin from upper valve body.

4.Slide manual valve out of body.
5.Cover downshift valve port with a finger. Then, working from underside of body, remove downshift valve retainer. Remove spring and downshift valve.
6.Apply hand pressure on pressure booster valve retaining plate and remove two screws. Slowly release pressure and remove plate, sleeve and pressure booster valve. Remove two springs and main regulator valve from same bore.
7.Apply pressure on throttle booster valve retaining plate and remove two screws. Slowly release pressure and remove plate, throttle boost valve and spring, and the manual low 2-1 scheduling valve and spring from the body.
8.Apply pressure on remaining valve retaining plate and remove eight screws.
9.Hold valve body so that plate is facing upward. Slowly release pressure and remove plate.
10.When removing various valves from valve body, keep all parts covered with your finger except the bore the valve is being removed from. Remove the 1-2 shift capacity scheduling and accumulator valves and springs, as shown in the Exploded View Of Upper Valve Body images.
11.Remove 2-3 backout valve and spring. Do not remove the 3-2 shift timing valve plug (manual low valve) if it is peened, preventing its removal. This condition will not affect transmission operation and is not cause for valve body replacement.
12.Remove 2-3 shift valve, spring, and throttle modulator valve.
13.Remove 1-2 shift valve, D2 shift valve and spring.
14.Remove coasting boost valve and spring.
15.Remove cut back control valve to complete the disassembly of the control valve.

CAUTION: All parts must be handled carefully to avoid nicking or burring the bearing or mating surfaces. Lubricate all internal parts with clean automatic transmission fluid before assembling them. Do not use any other lubricants except on gaskets and thrust washers. These may be coated with petroleum jelly to facilitate assembly. Always use new gaskets and seals when assembling transmission.

1.Remove screen from lower valve body.
2.Separate upper and lower valve bodies, and remove separator plate and gasket.
3.Remove manual valve retaining pin from upper valve body.

4.Slide manual valve out of body.
5.Cover downshift valve port with a finger. Then, working from underside of body, remove downshift valve retainer. Remove spring and downshift valve.
6.Apply hand pressure on pressure booster valve retaining plate and remove two screws. Slowly release pressure and remove plate, sleeve and pressure booster valve. Remove two springs and main regulator valve from same bore.
7.Apply pressure on throttle booster valve retaining plate and remove two screws. Slowly release pressure and remove plate, throttle boost valve and spring, and the manual low 2-1 scheduling valve and spring from the body.
8.Apply pressure on remaining valve retaining plate and remove eight screws.
9.Hold valve body so that plate is facing upward. Slowly release pressure and remove plate.
10.When removing various valves from valve body, keep all parts covered with your finger except the bore the valve is being removed from. Remove the 1-2 shift capacity scheduling and accumulator valves and springs, as shown in the Exploded View Of Upper Valve Body images.
11.Remove 2-3 backout valve and spring. Do not remove the 3-2 shift timing valve plug (manual low valve) if it is peened, preventing its removal. This condition will not affect transmission operation and is not cause for valve body replacement.
12.Remove 2-3 shift valve, spring, and throttle modulator valve.
13.Remove 1-2 shift valve, D2 shift valve and spring.
14.Remove coasting boost valve and spring.
15.Remove cut back control valve to complete the disassembly of the control valve.
