If necessary, clean the torque converter assembly and recheck the one-way clutch.

Replace the torque converter assembly if the one-way clutch still fails the inspection.

Inspect the torque converter assembly.

If any of the following problems are present, replace the torque converter assembly.

Malfunction:

A metallic sound is emitted from the torque converter assembly during the stall test or when the shift lever is moved to N.
The one-way clutch turns smoothly or locks in both directions.
The amount of powder in the ATF is more than the sample shown in the illustration (refer to the sample).

HINT:

The sample shows approximately 0.025 liters (0.026 US qts., 0.022 Imp. qts.) of ATF in Petri dish, which has been taken from the removed torque converter assembly.

HINT:

If the torque converter assembly is inspected or the ATF is replaced, it is necessary to clean the transmission oil cooler and oil pipe line.
Apply compressed air of 196 kPa (2.0 kgf/ cm² , 28 psi) into the inlet hose.
If a large amount of powder is found in the ATF, add new ATF using a bucket pump and clean the transmission oil cooler and oil pipe line again.
If the ATF is cloudy, inspect the transmission oil cooler.

Prevent deformation of the torque converter assembly and damage to the oil pump gear.

NOTE:

Make sure that all of the bolts are the same length and that the specified bolts are used.

HINT:

If there is any damage to the tip of a bolt for the torque converter assembly or to the bottom of a bolt hole, replace the bolt and torque converter assembly.

*a	Correct
*b	Incorrect
*c	Bottom is damaged

INSPECT DRIVE PLATE

Check the drive plate for damage.

Measurement Point

Set up a dial indicator and measure the runout at the 6 areas on the drive plate surface that contact the torque converter assembly.
Maximum runout

0.30 mm (0.0118 in.)

HINT:
- If the runout is more than the maximum or the drive plate is damaged, replace the drive plate.
- If installing a new drive plate, confirm that the spacers are oriented properly before tightening the bolts.
