8. Check foreign materials in oil pan to help determine causes of
malfunction. If the ATF 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, perform A/T fluid cooler
cleaning. Refer to AT- 1 4 , "
A/T Fluid Cooler Cleaning" .
9. Remove magnets from oil pan.
10. Disconnect A/T fluid temperature sensor 2 connector.
CAUTION:
Be careful not to damage connector.
11. Straighten terminal clip to free terminal cord assembly A/T fluid
temperature sensor 2 harness.
12. Disconnect revolution sensor connector.
CAUTION:
Be careful not to damage connector.
