Disassembly

1. NOTE: Note the location of the different length bolts for assembly.
Remove the 6 bolts and discard the transfer plate cover assembly.






2. NOTE: Note the location of the different length bolts for assembly.
Remove the 5 valve body bolts and the transfer plate assembly.






3. Remove and discard the valve body separator plate.





4. NOTE: Note the location of the check balls for assembly. Original valve bodies will have a valve latch circuit check ball and 6 other check balls. Valve bodies that have been replaced or updated will only have 6 check balls.
Remove the 6 check balls and if equipped, remove and discard the valve latch circuit check ball.

1. 6 check balls

2. Valve latch circuit check ball (vehicles equipped with the original valve body only)






5. Remove the lower valve body assembly.





6. Remove and discard the lower valve body separator plate and gasket.





7. Remove the manual valve from the valve body.





8. NOTICE: 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.

NOTE: Do not stone or polish any valves. If the valves do not move freely, install a new assembly.
Remove the individual valves and springs from the main control valve body and lower valve body by removing the retaining clips. See the Valve Body and Lower Valve Body illustrations at the beginning of this procedure for valve and spring locations. Clean valves, springs, main control valve body and lower valve body.






Assembly

1. NOTE: Do not stone or polish any valves. 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 and lower valve body. See the Valve Body and Lower Valve Body illustrations at the beginning of this procedure for valve and spring locations.


2. Install the manual valve in the valve body.





3. Install a new lower valve body separator plate and gasket on the main control valve body.





4. Install the lower valve body on the main control valve body.





5. NOTE: If the main control valve body had 7 check balls, do not install the valve latch circuit check ball removed during disassembly.
Install the 6 check balls in the valve body.






6. NOTICE: Do not reuse the valve body separator plate. Failure to install a new separator plate will result in transmission damage.

Install a new valve body separator plate and gasket.






7. NOTE: Install the different length bolts in the correct location as noted during disassembly.
Install the transfer plate assembly and hand-tighten the 5 bolts.

1. 63 mm (2.48 in) bolts

2. 35 mm (1.377 in) bolts






8. Tighten the 5 valve body bolts.
- Tighten to 12 Nm (106 lb-in).






9. NOTE: Install the different length bolts in the correct location as noted during disassembly.
Install the transfer plate cover assembly and hand-tighten the 6 bolts.

1. 63 mm (2.48 in) bolts

2. 35 mm (1.377 in) bolts






10. Tighten the 6 valve body bolts.
- Tighten to 12 Nm (106 lb-in).






11. If the valve body originally had 7 check balls and was assembled with 6 check balls, update the PCM (Powertrain Control Module) to the latest calibration.
