Apply air pressure to valve on the special tool.
With air pressure applied to the valve, inspect for leaks at the converter hub, the seams, drain plug, and the studs. A soap bubble solution can be applied around those areas to aid in the diagnosis. If a leak is found around the drain plug install a new drain plug and recheck the torque converter. If any other leaks are present, install a new or remanufactured converter.
Remove the air hose. Release the pressure, and then slowly release the press. Remove the converter. Remove the tool.
