CAUTION:

Do not damage connector.

28. Remove oil pan and oil pan gasket.

29. Check foreign materials in oil pan to help determine causes of

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 

AT-15, "A/T Fluid Cooler Cleaning"

 .
