74. Pour ATF into torque converter. Approximately 2 liter (2-1/8 US qt, 1-3/4 Imp qt) of ATF is
required for a new torque converter.
 When reusing old torque co nverter, add the same amount
of ATF as was drained.
75. Install torque converter while aligning notches of torque con- verter with notches of oil pump.
CAUTION:
Install torque converte r while rotating it.
76. Measure dimension “A” to make sure that torque converter is in proper position.
InspectionINFOID:0000000006226919
INSPECTION AFTER REMOVAL
Oil Pan
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, perform A/T fluid cooler
cleaning. Refer to TM-97, "
Cleaning".
