Torque Converter Clutch And Drive Plate Inspection

Inspect the one-way clutch.

1. Set SST into the inner race of the one-way clutch.
   

   SST

   09350-32014(09351-32010)
   

2. Install SST so that it fits in the notch of the torque converter hub and the outer race of the one-way clutch.

3. Stand the torque converter up and turn the SST.
   

   Standard:

   If the one-way clutch is turned clockwise, it rotates freely and if turned counterclockwise, it locks.
   

Determine the condition of the torque converter clutch assembly.

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

   Malfunction:
   1. A metallic sound is emitted from the torque converter clutch assembly during the stall test or when the shift lever is moved to N.
      
   2. The one-way clutch is free or locked in both directions.
      
   3. The amount of powder in the ATF is greater 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 is taken out from the removed torque converter clutch.

Replace the ATF in the torque converter clutch.

1. If the ATF is discolored and/or has foul odor, stir the ATF in the torque converter clutch and drain it.
   

Clean and check the oil cooler and oil pipe line.

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

   1. Apply compressed air 196 kPa (2.0 kgf/cm2, 28 psi) into the inlet hose.
      
   2. 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 line again.
      

2. If the ATF is cloudy, inspect the oil cooler (radiator).
   

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

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

2. All of the bolts should be the same length.
   

3. Bolts with washers must be used.
   

Check the drive plate damage.

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

Maximum runout:

0.30 mm (0.0118 in.)
