No...you are wrong Mike. As you start the car, the oil from the torque converter gets pumped out through the oil cooler and out through the pipe you have connected. I have just done this, and the first 4 litres or so of oil is black and dirty. As you top up the box with new fluid, it eventually runs clean out of the oil cooler outlet.
