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 converter, 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 converter while rotating it.

76. Measure dimension “A” to make sure that torque converter is in

proper position.

Inspection

INFOID: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"

.

one-way clutch outer race.

2.

When fixing bearing support with a check tool, rotate one-way
clutch spline using a screwdriver.

3.

Make sure that inner race rotates clockwise only. If not, replace
torque converter assembly.

1st One-way Clutch

Check operation of 1st one-way clutch.

1.
