Torque Converter And Drive Plate Inspection

Inspect the one-way clutch.

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

   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 clutch assembly.

1. Check that the following conditions are met:
   

   1. During the stall test or when the shift lever is in the N position, metallic sounds are not emitted from the torque converter clutch.
      
   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.
      If the results are not as specified, replace the torque converter clutch assembly.
      

   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 clutch.

Replace the ATF in the torque converter clutch.

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

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.
   

   1. Apply compressed air of 196 kPa (2 kgf/cm², 28 psi) from the inlet hose.
      
   2. 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. If 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 the torque converter clutch.
   

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

3. Washers must be used with the bolts.
   

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

Maximum runout:

0.20 mm (0.0079 in.)

Check the ring gear for any damage.
If the ring gear is damaged, replace the drive plate.
