Powder Method

  1. Thoroughly clean the suspected leak area.
  2. Apply an aerosol type powder, such as foot powder, to the suspected leak area.
  3. Allow the transaxle to reach the normal operating temperature of 176-194°F (80-90°C).
  4. Turn the engine OFF.
  5. Inspect the suspected leak area and trace the leak path through the powder to find the source of the leak.
  6. Make the necessary repairs to correct the leak. Once the leak point is found, the source of the leak must be determined and repaired.
