TORQUE CONVERTER CLUTCH AND DRIVE PLATE
INSPECTION
1. INSPECT ONE-WAY CLUTCH





a. Install SST so that it fits in the notch of the converter hub and outer race of the one-way clutch.
SST 09350-30020 (09351-32020)





b. Press on the serrations of the stator with a finger and rotate it.
c. Check if it rotates smoothly when turned clockwise and locks when turned counterclockwise.
If necessary, clean the converter clutch and retest the one-way clutch.
Replace the converter clutch if the clutch still fails the test.





2. MEASURE DRIVE PLATE RUNOUT AND INSPECT RING GEAR
a. Set up a dial indicator and measure the drive plate runout.
Maximum runout: 0.20 mm (0.0079 inch)
b. Check for damage to the ring gear.
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 the spacers and tighten the bolts.
