HELP..! 727 Tranny puking fluid from Dust Cover

Any idea what it could be..?

Trans is a 727 for Big Block. Been in use daily driving since 2005.

Just now started Leaking fluid from the front "Dust cover" at a steady Heavy drip once the car has been moving. When the car is still or OFF there is no drip..

Ya think maybe the Torque Converter fried..?..

Taking it to a very reputable Muscle Car Tranny Shop on Monday, but I would like a head's up so I don't sound like an idiot while talking to the man..

Thank you for your time.
