27. Push A/T assembly harness connector.CAUTION:
Do not damage connector.
28. Remove oil pan and oil pan gasket. Refer to TM-170, "
Oil Pan".
29. Check foreign materials in oil pan to help determine causes of malfunction. If the A/T fluid is very dark, smells burned, or con-
tains foreign particles, the frictional material (clutches, band)
may need replacement. A tacky film that will not wipe clean indi-
cates varnish build up. Varnish can cause valves, servo, and
clutches to stick and can inhibit pump pressure.
• If frictional material is de tected, perform A/T fluid cooler
cleaning. Refer to TM-152, "
A/T Fluid Cooler Cleaning".
30. Remove magnets from oil pan.
31. If an A/T fluid temperature sensor 2 is attached, disconnect the A/T fluid temperature sensor 2 connector
as shown below.
a. Disconnect A/T fluid temperat ure sensor 2 connector (A).
CAUTION:
Do not damage connector.
b. Straighten terminal clips ( ) to free terminal cord assembly and A/T fluid temperature sensor 2 harness.
