6. Remove snap ring from A/T assembly harness connector.
7. Push A/T assembly harness connector.CAUTION:
Be careful not to damage connector.
8. Remove bracket (1) (VK45DE), clips (2), oil pan (3) and oil pan gasket.
 : Vehicle front
 : Bolt (22)
 Drain plug (4)
9. Check foreign materials in oil pan to help determine causes of malfunction. If the ATF 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.
 If frictional material is de tected, perform A/T fluid cooler
cleaning. Refer to AT-13, "
A/T Fluid Cooler Cleaning".
10. Remove magnets from oil pan.
