INFOID:0000000008285915
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 detected, replace radiator after repair of
A/T. Refer to
CO-13, "Removal and Installation"
.
INSPECTION AFTER INSTALLATION
• Check A/T fluid leakage. Refer to
.
• Check A/T positions after adjusting A/T positions. Refer to
TM-180, "Inspection and Adjustment"
.
