Torque Converter Check Valve: Description and Operation
The drainback valve is located in the transmission cooler outlet (pressure) line. The valve prevents fluid from draining from the converter into the
cooler and lines when the vehicle is shut down for lengthy periods. Production valves have a hose nipple at one end, while the opposite end is threaded
for a flare fitting. All valves have an arrow (or similar mark) to indicate direction of flow through the valve.
