Transmission fluid everywhere

I filled a C4 once while it wasn't running. Put the 14 pints in or whatever and most of it went out the top vent as the convertor never filled. Same result. Im hoping you threw the convertor plug, that would be 2 bucks and the cost of new fluid. sector shaft seal would only leak about a pint as the level is not much higher than that location Im thinking lower than that to siphon out.
