If necessary, clean the converter clutch and retest the clutch. Replace the converter clutch if the clutch still fails the test.





2. MEASURE DRIVE PLATE RUNOUT AND INSPECT RING GEAR Set up a dial indicator and measure drive plate runout.
Maximum runout: 0.20 mm (0.0079 inch)
If runout is not within the specification or if the ring gear is damaged, replace the drive plate. If installing a new drive plate, note the orientation of spacers and tighten the bolts.
Torque:

3. MEASURE TORQUE CONVERTER CLUTCH SLEEVE RUNOUT
a. Temporarily mount the torque converter clutch to the drive plate.
Set up a dial indicator and measure the torque converter clutch sleeve runout.
Maximum runout: 0.30 mm (0.0118 inch)
If runout is not within the specification, try to correct by reorienting the installation of the torque converter clutch.
