2. Remove the 2 bolts and remove and discard the separator plate.





3. Remove the 3 check balls and the damper.
1. Check balls

2. Solenoid damper






4. Remove the manual valve.





5. NOTICE: Remove the valves by tapping the valve body on the palm of the hand to slide the valves out of the bores or by threading a 4-mm bolt into the valves and pulling them out. 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.

NOTICE: Do not stone or polish any valves or damage to the valves can occur. If the valves do not move freely, install a new assembly.

NOTE: The bypass valve is held in with a spring-loaded retainer. Be careful not to lose the retainer when removing it.
Compress the valve springs with a screwdriver and remove the retainers with a magnet. Use a pick to remove the bypass valve retainer. Remove the individual valves and springs from the main control valve body by tapping the valve body on the palm of the hand to slide the valves out of the bores. If needed, use a 4-mm bolt to thread into the valves to remove the valves. See the Valve Body illustration for valve and spring locations. Clean valves, springs and main control valve body.






Assembly

1. NOTICE: Do not stone or polish any valves or damage to the valves can occur. If the valves do not move freely during assembly, install a new valve body.

Install the valve body valves, springs and retaining clips in the main control valve body. See the Valve Body illustration at the beginning of this procedure for valve and spring locations.






2. Install the manual valve in the valve body.





3. Install the 3 check balls and the damper.
