CAUTION: Most valves are aluminum and cannot be removed using a magnet. Remove the valves by tapping the valve body on the palm of the hand to slide the valves out of the bores. It may be necessary to remove the valves and springs using a pick. If it is necessary to use a pick, use extreme caution to prevent damaging the valves or valve bores. If necessary, disassemble parts of the main control valve body in small groups. Take special care when handling the main control components, since they are the most precise and delicate parts of the transaxle. Neatly arrange the parts as they are removed to avoid mixing similar pieces.

CAUTION: Do not stone or polish any valves. If the valves do not move freely, install a new assembly.

Remove the individual valves and springs by removing the retaining clips and bore plugs. See the main control valve body assembly illustration (Figure) for valve and spring locations. Clean valves, springs and main control valve body.
Inspect the valve body sleeve for wear or damage.
- Verify that the hole in the valve body sleeve aligns with the hole in the circuit passage.
- Verify that the edge of the sleeve is 5.5 mm (0.21 in) above the valve body surface.

CAUTION: All the valves must be removed from the valve body during replacement of the sleeve to prevent possible damage.

CAUTION: The machined passage surfaces of the valve body that contact the press supports should be protected during sleeve replacement.

CAUTION: Do not press with excessive force when installing a new sleeve.

If a new sleeve is required, use the special tool and a suitable press to push the sleeve from the valve body.
