Automatic Transaxle Cooling Line help!!
 

I have pictures that i took if anyone is interested in helping me! I have a tranny fluid leak coming from a crack in a copper piece that goes from the radiator to the Automatic transaxle cooling line, i've tried soldering it, but it only hold for maybe a few minutes before the line heats up and melts what i did.. what is this copper piece called?! and if anyone knows where i can get one that would be AMAZING! Dealership said they don't have just that piece and it doesn't come with the auto. trans. cooling lines they tried to sell me... i have an 02 eclipse GT 3.0 ,... if there's anyone who can help i would total appreciate it!!:(
