    INSPECT TORQUE CONVERTER ASSEMBLY


    1. A01CB2YE02

      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 heavily when turned counterclockwise.

        If necessary, clean the converter and recheck the one-way clutch.

        Replace the torque converter if the one-way clutch still fails the inspection.

    2. A01CBMTE12

      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 smooth or heavy in both directions.

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

        Tip:

        The sample shows approximately 0.025 liters (0.026 US qts, 0.022 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 and oil pipe line.


      1. A01CDFH

        If the torque converter is inspected or the fluid is changed, clean the oil cooler and oil pipe line.

        Tip:

        • Spray compressed air at 196 kPa (2.0 kgf/cm2, 28 psi) into the inlet hose.

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

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

    5. A01CFZGE21

      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.

    INSPECT DRIVE PLATE


    1. Check the drive plate for damage.

    2. A01CFPZE03

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

      Table 1. Text in Illustration
      *1 Measurement Point
      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).
