  1. Determine the condition of the torque converter clutch.

    1. Check that the following conditions are met:

      1. During the stall test or when the shift lever is on N, metallic sounds are not emitted from the torque converter clutch.
      2. The 1-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.
