Put some paper down on the floor in the area of the leak. You may be able to see color and feel texture of the fluid. The tranny connector is on the passenger side -- but kind of in the center. You'd know if it was tranny fluid. AC dripping would likely be more towards the front end, however if it's coming from the AC "system" it could be further back. Look at all hosed on right side in the area starting in the front and working your way back. Hope you find it soon.
