First off, there is no overkill when it comes to keeping transmissions cool IMO. General rule of thumb is "put the biggest damn tranny cooler that you can fit in there." The B+M 70264 is the most popular cooler on this site that I know of. It does work well. I recently switched to B+M 1.5x10.5x11. Its about 1/3 bigger. I like it so far, temps have been completely in check.
You want to make sure the trans fluid gets up to and stays around operating temperature... I think that's a minimum of around 180 degrees.

I've been running Derale part number 13104. Runs nice and cold. During the cooler months here in OK while at 30 mph and up, the temp gauge won't go over 120. Will bump against 150 at idle if I've been driving a lot or romping on it.
