Wipe the transmission down with a rag! Clean up all the Transmission Fluid. Now start the vehicle and look under it see where it is leaking from. The front, the pan, or the rear? The front and rear will need a new seal. The pan will need a new gasket. You have to remove the transmission to replace the front seal. You may also want to change the filter while your this far along. Youre only talking about 1-2 hrs even for a first timer to replace the pan gasket and re seal and under $25..
