    5R55E Stuck Reverse Servo Piston

    Hah, yeah, that is probably what will happen. Looking again at the date codes, I think this one I bought might actually be an '04 and not an '01. That makes me feel a bit better, as my valve body has been solid in my '05... think they might have worked out the bugs by then. Lee
