Peter (psfred) hit it on the head!!! It was ATF that traveled down from the exhaust hanger to the exhaust itself and got burned there; especially the incline I mentioned actually had a little off camber to the right (USPS side) where the exhaust is.
Drained and refilled tranny with Valvoline Maxlife ATF with stop leak. Gone from few drops a day to virtually no drops for months now. Just did a fluid swap to Mobil1 synthetic ATF so I'm crossing my fingers hoping the leak does not return

Frank.
