Buddy has a 2005 ford expedition Eddie bauer Edition was leaking transmission fluid from a rusted line on the bottom of the radiator or cooler on the left side going to the auxiliary trans cooler. Bought some parts from Rock auto and they weren't even for the auxiliary cooler, can't find what part it is. Here's a pic from another thread it's the #3 line please any help would so appreciated not trying to hack this thing together.
