Remove oil pan using power tools, and oil pan gasket.
NOTE: Do not reuse oil pan bolts.
Check foreign materials in oil pan to help determine causes of malfunction. If the fluid 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.
NOTE: If frictional material is detected, replace radiator after repair of A/T. Refer to "RADIATOR ".
