It might seem like a lot of fluid, but with any kind of oil based fluid, a little goes a long way. I would wash everything down really good, start up your vehicle without moving it or taking out of park and see if you can see a leak.
If you have to drive it to get it to leak, that is a different story, since fluid will travel backwards a lot because of the forward motion and air blowing on a driven vehicle. If you have to drive it, drive it for a short distance and stop and re-inspect to see if you can locate the leak and report back.
