what type of leak is this and what should i do

Its either your automatic transmission cooler lines going to the lower portion of the radiator or your power steering hoses has started leaking, Have a mechanic take a look at this because driving low on transmission fluid can damage your transmission and cost around $2000 to rebuild, I see quite a few 5 star shops on http://repairpal.com/directory put in your zip code and click on rating three or four shops close to your area.
