Yeah, I have a feeling you are right. If the dipstick tube, selector seal and speedo drive don't leak, and the pan gasket is intact and torqued right, then it doesn't matter if the level in the trans is high when parked.

I put a loop in the rubber hoses and cable-tied them up a bit higher than the cooler and this helped a lot. It seems to stop (or slow) the drain back to the trans from the cooler. I suppose you could find a low location for the cooler, but the radiator is a good spot in the airflow.
