1. Drain A/T fluid through drain plug.
2. Remove torque converter by holding it firmly and turing while pulling straight out.
3. Check torque converter one-way clutch using a check tool as shown.
a. Insert a check tool into the groove of bearing support built into one-way clutch outer race.
b. While holding bearing support with a check tool, rotate one-way clutch spline using suitable tool.
c. Make sure that inner race rotates clockwise only. If not, replace torque converter assembly.
4. Remove bolts and converter housing from transmission case. CAUTION:
Do not scratch converter housing.

17. Install oil pan to transmission case. Refer to TM-199, "Oil Pan".
18. Install torque converter.
a. Pour ATF into torque converter. NOTE:
• Approximately 2 liters (2-1/8 US qt. 1-3/4 Imp qt) of fluid isrequired for a new torque converter.
• When reusing old torque converter, add the same amount of fluid as was drained.
b. Install torque converter while aligning notches of torque con- verter with notches of oil pump.
CAUTION:
Install torque converter while rotating it.
c. Measure distance "A" to make sure that torque converter is in proper position.
