Torque Converter Clutch And Drive Plate Inspection

Inspect the one-way clutch.

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

2. Stand the torque converter assembly up and turn the SST.
   Check that it rotates smoothly when turned clockwise and locks up when turned counterclockwise.

   If necessary, clean the torque converter assembly and check the one-way clutch.
   Replace the torque converter assembly if the one-way clutch still does not operate as specified.
   

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 greater than the sample shown in the illustration.
      

   HINT:

   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 assembly.

Replace the ATF in the torque converter assembly.

1. If the ATF is discolored and/or has a foul odor, rock the torque converter assembly to move the fluid around inside it. Drain the ATF with the mounting surface of the torque converter assembly facing upward.
   

Clean and check the oil cooler and oil pipe line.

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

   HINT:

   1. Spray compressed air of 196 kPa (2 kgf/cm², 28 psi) from the inlet hose.
      
   2. If excessive fine powder is found in the ATF, add new ATF using a bucket pump and clean it again.
      

2. If the ATF is cloudy, inspect the oil cooler (radiator).
   

Prevent deformation of the torque converter assembly 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 assembly and on the bottom of the bolt hole, replace the bolt and the torque converter assembly.
   

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

3. Washers must be used with the bolts.
   

Check the drive plate for damage.

Set up a dial indicator and measure the run out of the 6 portions around the torque converter assembly fitting surfaces.

Maximum runout:

0.30 mm (0.0118 in.)
