Press on the serrations of the stator with a finger and rotate the stator. Check that it rotates smoothly when turned clockwise and locks when turned counterclockwise.

If necessary, clean the converter and recheck the 1-way clutch.

Replace the converter if the 1-way clutch still fails the inspection.

If the inspection result of the torque converter satisfies the following conditions, replace the torque converter.

Malfunction

A metallic sound is emitted from the torque converter during the stall test or when the shift lever is moved to N.

The 1-way clutch is free or locks in both directions.

The amount of powder in the ATF is more than the sample shown in the illustration (see the sample).

HINT:

The sample shows approximately 0.025 liters (0.026 US qts, 0.022 Imp. qts) of ATF that was taken out from a removed torque converter.

Replace the ATF in the torque converter.

If the ATF is discolored and/or has a foul odor, stir the ATF in the torque converter thoroughly and drain the ATF with the torque converter facing upward.

Clean and check the oil cooler and oil pipe line.

If the torque converter is inspected or the ATF is replaced, clean the oil cooler and oil pipe line.

HINT:

Apply compressed air at 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 oil cooler and oil pipe again.

If the ATF is cloudy, inspect the oil cooler.

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

When there is any damage to the end of a bolt for the torque converter and to the bottom of the bolt hole, replace the bolt and the torque converter.

All of the bolts should be the same length.

Bolts with washers must be used.

2. INSPECT DRIVE PLATE

Check the drive plate for damage.

Set up a dial indicator and measure the runout of the 6 portions around the torque converter contact surfaces.
