CONTROL VALVE WITH TCM REMOVAL AND INSTALLATION
Removal
1. Disconnect the battery cable from the negative terminal.
2. Drain ATF through drain plug.
3. Disconnect heated oxygen sensor 2 harness connector.
4. Disconnect A/T assembly harness connector.
5. Remove snap ring from A/T assembly harness connector.
6. Push A/T assembly harness connector.
CAUTION:
Be careful not to damage connector.
7. Remove oil pan and oil pan gasket.
8. 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- 1 4 , "
A/T Fluid Cooler Cleaning" .
