Trans cooler questions...

I have a Moroso heat sink-type trans cooler and was thinking of using it rather than a traditional cooler.

Questions are: Has anyone ran a heat sink type of cooler?

Has anyone been successful mounting it (or any cooler) under the car somewhere? I'd really like to not have it up front for clutter reasons and was also thinking about the heat transfer running lines near the hot headers and motor.
