CAUTION:
Do not damage connector.
28. Remove oil pan and oil pan gasket. Refer to
TM-172, "Removal and Installation"

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.
•

cleaning. Refer to

.
