TRANSMISSION FLUID LEAK

Cadillac Deville

In my 2003 Cadillac Deville, 60,000 miles, standard Northstar engine, I have a transmission fluid leak of about a quart a week. If I keep the fluid level up, the car runs well. Is this serious, like a new seal required, or could it be something simple?
Thanks.
