Disassembly And Assembly: Disassembly
Remove the valve body from the transmission and place the valve body on a clean oil absorbent work surface. Position wood blocks at each end of the valve body to provide a stable work fixture.
- Remove the solenoids (1 - 4) from the valve body.NOTE:
Each type solenoid has a unique color end cover.
- 1 = System Pressure Regulator Solenoid
- 2 = Pressure Regulator Solenoids
- 3 = Dog Clutch Solenoids
- 4 = Limp Home Mode Solenoid
- 5 = Pressure Sensor
- 6 = Manual Valve
- Remove the pressure sensor (5) and manual valve (6) from the valve body.
- Position the valve body on the wooden blocks with outer side up.
- Remove the screws holding the valve body halves together.
- Separate the outer valve body from the separator plate.
- Lift the separator plate upward and off of the inner valve body.
- Remove the guide pins from the inner valve body.
- Remove the color coded check valves and the single check ball from the inner valve body.
- Position the outer valve body on the work surface inside up to gain access to the valve retaining spring clips.NOTE:
DO NOT damage the filter screen during removal.
- Using a suitable prying tool, remove the filter screen from the bore in the outer valve body.
- Remove the bullets, sleeves, and dog clutch switch valves from the bores in the outer valve body.
- Using a suitable prying tool, remove the spring clips holding the pressure control valve plugs from the cast ports in the outer valve body.
- Remove the plugs, pressure control valves and springs from the bores in the outer valve body.
- Rotate the outer valve body to gain access to the pressure regulator and lubrication valves.
- The retaining plates (3) and spring clip (6) are located in pockets (8) in the outer valve body (1).
- Remove the support plate (3) holding the spring and converter pressure valve (2) in the bore in the outer valve body (1).
- Remove the spring and TCC switch valve (2) from the bore in the outer valve body (1).
- Remove the retainer (3) holding the plug (5), spring and system pressure regulator valve (7) in the bore in the outer valve body (1).
- Remove the plug (5), spring and system pressure regulator valve (7) from the bore in the outer valve body (1).
- Remove the spring clip (6) holding the plug (5), spring and lubrication valve (4) in the bore in the outer valve body (1).
- Remove the plug (5), spring and lubrication valve (4) from the bore in the outer valve body (1).
- Place the inner valve body on the clean work surface with the valves bores facing up.NOTE:
The spring clips holding the plugs in the inner valve are located in pockets on the separator plate side of the inner valve body.
- Press each of the valve plugs downward and remove the spring clips holding the valves in the bores in the inner valve body.
- Remove the plug, spring and boost valve from the bore in the inner valve body.
- Remove the plug, spring and solenoid limit valve from the bore in the inner valve body.
- Remove the plugs, plug valves, pressure control valves, and springs from the bores in the inner valve body.
- Remove the plug, spring, and Limp Home Mode latch valve from the bore in the inner valve body.
- Perform the cleaning and inspection procedures.
