    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 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 more 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 0.025 liters (0.026 US qts, 0.022 Imp. qts) of ATF taken from a removed torque converter clutch.
  1. Replace the ATF in the torque converter clutch.

    1. AT 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 upward.
