Whine Noise

NOTE: Do not confuse this noise with pump whine noise, which is usually noticeable in Park, Neutral and all other gear ranges. Pump whine will vary with line pressure.

You may notice a torque converter whine when the vehicle is stopped and the transmission is in Drive or Reverse. This noise will increase as you increase the engine RPM. The noise will stop when the vehicle is moving or when you apply the torque converter clutch, because both halves of the converter are turning at the same speed.

Perform a stall test to make sure the noise is actually originating from the converter:

  1. Place your foot on the brake.
  2. Place the gearshift lever in the Drive position.
    3. CAUTION: You may damage the transmission if you depress the accelerator for more than 6 seconds.
  3. Depress the accelerator to approximately 1200 RPM for no more than 6 seconds.
