what benebob said - i insulated the temp sender (on top of my external filter) with some adhesive foam-backed aluminum tape (Home Depot, etc.) and it dropped the temps a bit. you're probably getting an inaccurate reading.

also, remove your plastic belly pan in the summer, and replace it in the winter (keep the heat in, and road slush and salt out ). this will have a pretty big effect on reducing your tranny temps in the summer. i usually change my oil twice a year (approx every 4k miles or so), before the under tray goes on, and then right after it comes off, for convenience.
