4. Apply air pressure to the valve on the special tool.
5. 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.
