Inspection and Adjustment

INSPECTION AFTER REMOVAL

Check foreign materials in oil pan to help determine causes of malfunction. If the A/T fluid is very dark, smells burned, or contains foreign particles, the frictional material (clutches) may need replacement. A tacky film that will not wipe clean indicates varnish build up. Varnish can cause valves and clutches to stick and can inhibit pump pressure.

• If frictional material is detected, perform A/T fluid cooler cleaning. Refer to Cleaning.

INSPECTION AFTER INSTALLATION

Start the engine and check visually that there is no leakage of A/T fluid.

ADJUSTMENT AFTER INSTALLATION

When replaced the control valve & TCM, perform “ADDITIONAL SERVICE WHEN REPLACING CONTROL VALVE & TCM”. Refer to Description.
