: Bolt (22)

Drain plug (3)
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 5 , "
A/T Fluid Cooler Cleaning" .
9. Support A/T assembly with a transmission jack. CAUTION:
When setting transmission jack, place wooden blocks to
prevent from damaging control valve with TCM and trans-
mission case.
10. Remove rear engine mounting member with power tool. Refer to AT- 2 6 6 , "
