2WD : Inspection and AdjustmentINFOID:0000000006228121
INSPECTION AFTER REMOVAL
Check foreign materials in oil pan to help determine causes of mal-
function. If the ATF is very dark, smells burned, or contains foreign
particles, the frictional material (clutches, band) may need replace-
ment. 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 det ected, perform A/T fluid cooler
cleaning. Refer to TM-97, "
Cleaning".
INSPECTION AFTER INSTALLATION
Check A/T fluid leakage Refer to TM-175, "Inspection".
