Why am i getting transmission fluid in the big black hose with circles on it where the gas should be coming through? At first it was coming through the coolant holder so i had a new radiator put on now this. And how much is this going to cost? I am having to add unsually fluid and looses power,and smokes when i start up or take off

Trans fluid line leaking where it hooks to the' top' of the radiator most likely... take it back to whomever installed the new radiator and get them to check it out!
