    WARNING: To prevent injury, wear eye protection when using pressurized air.
  8. With the special tool installed and air pressure applied to the valve on the special tool, inspect for leaks at the converter hub, seams, and studs. A soap bubble solution may be applied around those areas to aid in diagnosis. If any leaks are present, install a new or remanufactured torque converter.
  9. Remove the air hose. Release the pressure and then slowly release the press, and the tool. Remove the torque converter from the press.
