5. 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.
6. Remove the air hose. Release the pressure and then slowly release the press, and the tool. Remove the torque converter from the press.
