  7. 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, 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 A/T FLUID COOLER CLEANING  under A/T FLUID.
  8. Support transmission assembly with a transmission jack.
    CAUTION: Remove setting transmission jack, place wooden blocks to prevent from damaging control valve and transmission case.
