TORQUE CONVERTER CLUTCH AND DRIVE PLATE INSPECTION


  1. INSPECT TORQUE CONVERTER CLUTCH ASSEMBLY


    1. A01CDSVE02

      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.

        *b Turn
        *c Lock
        *d Free

        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 assembly.


      1. If the inspection result of the torque converter assembly satisfies one of the following conditions, replace the torque converter clutch 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 ATF is greater than the sample shown in the illustration (See the sample).

        Tech Tips

        The sample shows approximately. 0.025 liters (0.026 US qts, 0.022 Imp. qts) of ATF that is taken out from a removed torque converter clutch.

    3. Replace the ATF in the torque converter clutch.


      1. If the ATF is discolored and/or has a 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.


        • Apply compressed air of 196 kPa (2 kgf/cm2, 28 psi) into the inlet hose.

        • 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 any marks due to interference are found on the end of the bolt for the torque converter or on the bottom of the bolt hole, replace the bolt and torque converter.

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

      3. Bolts with washers must be used.

  2. INSPECT DRIVE PLATE

    2. 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.)

      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 Click here.
