4. Set manual shaft to position P.
5. Remove park/neutral position (PNP) switch.
6. Remove bracket from transaxle case.
7. Remove revolution sensor from transaxle case.
8. Remove O-ring from revolution sensor.
9. Remove oil pan and oil pan gasket.

Do not reuse oil pan bolts.
10. Check foreign materials in oil pan to help determine causes of
malfunction. If the fluid is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indicates
varnish build up. Varnish can cause valves, servo, and clutches
to stick and can inhibit pump pressure.

If frictional material is detected, replace radiator after
repair of A/T. Refer to CO-12, "
RADIATOR" .
11. Remove magnets from oil pan.
12. Remove control valve assembly according to the following procedures.
a. Remove snap ring from terminal body.
b. Push terminal body into transaxle case and draw out terminal
cord assembly.
