TORQUE CONVERTER AND DRIVE PLATE INSPECTION


  1. INSPECT TORQUE CONVERTER ASSEMBLY


    1. A005TPLE03

      Inspect the one-way clutch.


      1. Press on the splines of the stator with a finger and rotate it. Check that it rotates smoothly when turned clockwise and rotates with difficulty 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 inspection.

      Determine the condition of the torque converter assembly.


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

        Malfunction:


        • A metallic sound is emitted from the torque converter assembly during the stall test or when the shift lever is moved to N.

        • The one-way clutch is free or locked in both directions.

        • The amount of powder in the fluid is greater than the sample shown in the illustration.

        Tech Tips

        The sample shows approximately 0.25 liters (0.26 US qts, 0.22 Imp. qts) of fluid that is taken out from the removed torque converter.

    3. Replace the fluid in the torque converter.


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

    4. Clean and check the oil cooler.


      1. If the torque converter is inspected or the fluid is changed, clean the oil cooler.

        Tech Tips


        • Spray compressed air at 196 kPa (2 kgf/cm2, 28 psi) into the hole of oil cooler.

        • If an excessive amount of fine powder is found in the fluid, add new fluid using a bucket pump and clean the oil cooler again.

      2. If the fluid is cloudy, inspect the oil cooler.

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


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

      2. Make sure all of the bolts are the same length.

      3. Bolts with washers must be used.

  2. INSPECT DRIVE PLATE


    1. Check the drive plate for damage.

      *1 Measurement Point

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

      Maximum runout
      0.30 mm (0.0118 in.)

      If the runout is more than the maximum or the drive plate is damaged, replace the drive plate Click here.
