Answer
Well, start by cleaning everything of fluid then double check your pan bolts, the plug, dipstick tube fitment and it's o-rings and the modulator fitment and o-ring.  If the stick shows a level cold then start the engine allow it to run to temperature then cycle from drive to reverse a few times then park.  Check the level warm and idling to get the accurate level.  If you filled it to level while off and cold you may have overfilled the system and thus it expanded and forced excess fluid out under pressure.
