Disassembly

CAUTION: Take care when removing the line pressure regulator valve. The pressure regulator cushion spring and valve spring have a tendency to shoot-out, resulting in potential injury.

IMPORTANT: The valve body should only be disassembled if directed by the diagnostic charts or if the transaxle is being overhauled. Care must be taken when removing valve body valves as these valves are not serviced separately. Whenever the valve body is disassembled, new spacer plate gaskets must be installed.





1. Remove solenoid cover-to-valve body bolts and remove solenoid cover.
2. Lift solenoid connector plate off solenoid valve pins using care not to damage connector plate.

IMPORTANT: Note position of solenoid valves before removing.

3. Remove solenoid valves by using a twisting motion.
4. Remove bolt retaining the two halves of the valve body.

IMPORTANT: Note ball check valve positions when taking two halves apart.

5. Remove valves from the upper and lower valve body halves.

IMPORTANT: Remove detent arm on upper valve body before removing line pressure regulator valve.

When diagnosing the valve body, the following is a list of possible areas of concern:
- Valve stuck or sticking in bore
- Torn or split gasket
- Irregular gasket surfaces on machined face of valve body
- Cracked housing (in or around fluid passages)
- Spacer plate damaged (warped, scored, holes elongated)
- Valve or housing bore scored
- Broken or collapsed springs
- Stripped bolt holes
- O-rings damaged (on valves)
- Valve assemblies incorrectly installed (valve installed in the wrong order, valve installed in the wrong direction, valve installed in the wrong bore)
- Solenoid inoperative
- Poor connection at connector plate

The valve body must be replaced if the valves cannot be freed up by cleaning, or if the valves or the housing are damaged. If there is no apparent damage to the valves or the housing, then it should be cleaned and reassembled. Make sure the valves move freely in their respective bores after cleaning and reassembly. Under no circumstances should you attempt to debur valves. Also, never use emery cloth or crocus cloth to polish or repair a valve or the housing bore. The abrasive material on the cloths will damage the surface finish of the valves and valve body.
