1. Drain ATF through drain plug.
2. Remove torque converter.
3. Check torque converter one-way clutch using check tool as shown. Insert check tool into the groove of bearing support built into one-way clutch outer race. While fixing bearing support with check tool, rotate one-way clutch spline using flat-bladed screwdriver. Check to make sure the inner race rotates clockwise only. If not, replace torque converter assembly.
4. Remove oil charging pipe and oil cooler tube.
5. Set manual shaft to "P" position.
6. Remove PNP switch.
7. Remove oil pan and oil pan gasket. Always replace oil pan bolts as they are self-sealing bolts.

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 may inhibit pump pressure. If frictional material is detected, replace radiator after repair of A/T. Refer to «RADIATOR»(ref-213044-S22202889982005123100000) .
