Torque Converter Clutch And Drive Plate Inspection

Inspect the one-way clutch.

1. Install SST into the inner race of the one-way clutch.
   

   SST

   09350-32014(09351-32010)
   

2. Set SST so that it fits in the notch of the torque converter hub and the outer race of the one-way clutch.

3. With the torque converter assembly standing on its side, check that the clutch locks when SST is turned counterclockwise and rotates freely and smoothly when SST is turned clockwise.

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

Determine the condition of the torque converter assembly.

1. Check that the following conditions are met:
   

   1. During the stall test or when the shift lever is in N, metallic sounds are not emitted from the torque converter assembly.
      
   2. The one-way clutch turns in one direction and locks in the other direction.
      
   3. The amount of powder in the ATF is not more than the sample shown in the illustration.
      
   If the results are not as specified, replace the torque converter assembly.
   

   HINT:

   The sample illustration shows approximately 0.025 liters (0.026 US qts, 0.022 Imp. qts) of ATF taken from a removed torque converter assembly.

Replace the ATF in the torque converter assembly.

1. If the ATF is discolored and/or has a foul odor, stir the ATF in the torque converter assembly thoroughly and drain the ATF with the torque converter assembly facing upward.
   

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

1. When any marks due to interference are found on the end of a bolt for the torque converter assembly and on the bottom of the bolt hole, replace the bolt and torque converter assembly.
   

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

3. Make sure no spring washers are missing.
   

Check the drive plate for damage.

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.)
