Problem is your leak may be nowhere near where you see the fluid gathering, it may be well to the front of that and being blown back to where it collects.
I recommend adding dye to the transmission before you take it in, as then the tech can use a UV and a darkened stall to trace forward to where it might be coming from.
RU sure it is transmission fluid, or possibly is it power steering, etc?
I'd check your fluids, particularly the transmission, as some dealers or just prior owners will overfill on purpose to make it look good just long enough to get rid of.
