Sounds like a seal leaking under pressure (at the cooler), rather than a static leak (pan gasket). Pan gasket leaks get a little worse when driven, but slow down when the vehicle is stopped. They don't usually stop. Pressure leaks, well, they are! No pressure, no leak. You have already done most of your own diagnosing. Now, find a replacement set of Tranny cooler seals.

Subject: Can Permatex React with ATF?

Also, only leaks aggressively under load.� When parked after a drive, the
drip slows and pretty much stops.

Any thoughts appreciated.
