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
.

TRANSMISSION ASSEMBLY
Check torque converter one-way clutch using a check tool as shown
at figure.
1.
Insert a check tool into the groove of bearing support built into
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.
Install 1st one-way clutch (1) to front brake hub (with under drive
carrier).
2.
Hold 1st one-way clutch.
3.
Check front brake hub for correct locking and unlocking direc-
tions. If necessary, replace 1st one-way clutch.
Under Drive Sun Gear
Check for deformation, fatigue or damage. If necessary, replace the under drive sun gear.
Mid Carrier Assembly
Check for deformation, fatigue or damage. If necessary, replace the mid carrier assembly.
Rear Carrier Assembly
Check for deformation, fatigue or damage. If necessary, replace the rear carrier assembly.
Reverse Brake Drive Plates
Check facing for burns, cracks or damage. If necessary, replace the plate.
Reverse Brake Retaining Plate, Driven Plates and Dish Plates
Check facing for burns, cracks or damage. If necessary, replace the plate.
