    Hi all,

    What is the function of the tube that crosses over from the inlet and outlet ports for transmission fluid cooling on the side of the Ford 4R100? I can slightly see into the tube while looking into the banjo fitting on one end and it looks like there may be a spring in there. The E4OD doesn't have this tube.
    The trans' torque convertor grenaded leaving a layer of metal in the pan. I'm hesitant to reuse this tube over again since I can't really seem to flush it. Any direction for me?

    Thanks,

    Nick

    Just a little more clarification: The trans is out of a 1998 Expedition equipped with a 5.4L engine.
