Torque Converter Clutch And Drive Plate Inspection

Inspect the one-way clutch.

1. Press on the spline of the stator with a finger and rotate it. Check that it rotates smoothly when turned clockwise and rotates heavily when turned counterclockwise.
   If necessary, clean the torque converter and recheck the one-way clutch.
   Replace the torque converter if the one-way clutch still fails the check.
   

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 item :
   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.
      
   1. The one-way clutch is free or locked in both directions.
      
   1. The amount of powder in the ATF is not 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 the taken out from the removed torque converter.

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 exchanged, clean the oil cooler and oil pipe line.
   

   HINT:

   1. Spray compressed air of 196 kPa (2.0 kgf/ cm², 28 psi) into the inlet hose.
      
   2. If plenty of fine powders are identified in the ATF, add new ATF using a bucket pump and clean it 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 the 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.
If the runout is not within the specification or the drive plate is damaged, replace the drive plate.
If installing a new drive plate, be careful of the orientation of the spacers and tighten the bolts (CAMRY_ACV40 RM0000021ZR03MX_01_0116.html).

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

Maximum runout:

0.30 mm (0.0118 in.)
