5. Set manual shaft to “P” position.
6. Remove PNP switch.
7. Remove bracket from transaxle case.
8. Remove revolution sensor from transaxle case.
9. Remove O-ring from revolution sensor.
10. Remove turbine revolution sensor (power train revolution sen-
sor) from transaxle case.
11. Remove O-ring from turbine revolution sensor (power train revo-
lution sensor).
12. Remove oil pan fitting bolts.
13. Remove oil pan and oil pan gasket.
14. Check foreign materials in oil pan to help determine causes of
malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, frictional material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish 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.
15. Remove magnets from oil pan.
16. Remove control valve assembly according to the following procedures.
a. Remove snap ring from terminal body.
CAUTION:
Do not expand snap ring excessively.
b. Push terminal body into transaxle case and draw out terminal
cord assembly.
