TORQUE CONVERTER CLUTCH AND DRIVE PLATE INSPECTION


  1. INSPECT TORQUE CONVERTER CLUTCH ASSEMBLY

    A01J445E01

    1. Inspect the 1-way clutch.


      1. Install SST in the inner race of the 1-way clutch.

        SST
        09350-32014   ( 09351-32020 )
      2. A01J6XUE01

        Press on the serrations of the starter with a finger and rotate it.

        Check if it rotates smoothly when turned clockwise and locks when turned counterclockwise.

        If the results are not as specified, clean the converter and recheck the 1-way clutch. If the results still are not as specified, replace the torque converter clutch assembly.

      Determine the condition of the torque converter clutch.


      1. Check that the following conditions are met:


        • During the stall test or when the shift lever is on N, metallic sounds are not emitted from the torque converter clutch.

        • The 1-way clutch turns in one direction and locks in the other direction.

        • The amount of powder in the ATF is not greater than the sample shown in the illustration.

        If the results are not as specified, replace the torque converter clutch assembly.

        Tech Tips

        The sample illustration shows approximately 0.25 liters (0.26 US qts, 0.22 Imp. qts) of the ATF taken 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 thoroughly and drain the ATF with the torque converter facing up.

      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.

        Tech Tips


        • 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).

    5. A01J4FKE05

      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 clutch and on the bottom of the bolt hole, replace the bolt and torque converter clutch.

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

      3. Make sure no spring washers are missing.

  2. INSPECT RUNOUT OF DRIVE PLATE AND RING GEAR

    A01J34KE01

    1. Set up a dial indicator and measure the drive plate runout.

      Maximum runout
      0.20 mm (0.0079 in.)

      If the runout is greater than the maximum or if the ring gear is damaged, replace the drive plate. If installing a new drive plate, note the orientation of the spacers and tighten the bolts.

      Torque:
      178 N*m  { 1,820 kgf*cm, 132 ft.*lbf }

  3. INSPECT RUNOUT OF TORQUE CONVERTER CLUTCH ASSEMBLY

    A01J3SKE01

    1. Temporarily mount the torque converter clutch to the drive plate. Set up a dial indicator.

      Maximum runout
      0.30 mm (0.0118 in.)

      If the runout is greater than the maximum, try to correct it by changing the installation direction of the torque converter clutch.

      If the runout cannot be corrected, replace the torque converter clutch.

      Tech Tips

      Mark the position of the torque converter clutch so that it can be installed correctly later.

    2. Remove the torque converter clutch.
