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 

TM-173, "Inspection"

.

• Check A/T positions after adjusting A/T positions. Refer to 

TM-180, "Inspection and Adjustment"

.

ADJUSTMENT AFTER INSTALLATION

Adjust A/T positions. Refer to
