CONTROL VALVE WITH TCM ASSEMBLY REMOVAL AND INSTALLATION

Removal
1. Disconnect the battery cable from the negative terminal.
2. Drain ATF through drain plug.
3. Remove front cross bar.
4. Disconnect heated oxygen sensor 2 harness connector.
5. Disconnect A/T assembly harness connector.

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 detected, perform A/T fluid cooler cleaning. Refer to AT-15, "A/T Fluid Cooler Cleaning". A/T Fluid Cooler Cleaning

10. Remove magnets from oil pan.
