INSPECTION
1. INSPECT TORQUE CONVERTER CLUTCH ASSEMBLY
SST 09350-30020 (09351-32020, 09351-32010)
a) Inspect the one-way clutch.

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

2) Press on the serrations of the starter with a finger and rotate the starter.
Clean the converter and retest the one-way clutch.
When the one-way clutch is turned clockwise, it rotates freely and when turned counterclockwise, it locks.
b) Determine the condition of the torque converter clutch assembly.

1) If the inspection result of the torque converter clutch assembly does not satisfy the standard conditions, replace the torque converter clutch assembly.
Malfunction item: A metallic sound is heard from the torque converter clutch during a stall test or when the shift lever is in the N position. The one-way clutch is free or locked in both directions.
Fine powder exceeding the sample limit is identified in ATF.

HINT: The sample shows the auto fluid of approximately 0.25 liters (0.26 US quarts, 0.22 Imp. quarts) of ATF that is taken out from the removed torque converter clutch.

c) Replace the ATF in the torque converter clutch.
1) If the ATF is discolored and/or has a foul odor, completely stir the ATF in the torque converter clutch and drain the ATF

2. INSPECT RUNOUT OF DRIVE PLATE AND RING GEAR SUB-ASSEMBLY

a) Set up a dial indicator and measure the drive plate runout.
Maximum runout: 0.20 mm (0.0079 inch)
If runout exceeds the maximum value or if the ring gear is damaged, replace the drive plate.
