2003 Saturn Vue Transmission cooling lines

My mechanic told me my transmission fluid cooling lines are leaking slightly at the connection of the metal to the rubber hose. He said it's a minor leak, however if it goes, it could damage the transmission. Now the bad part, he said e can't find the parts anywhere and they can't be made. This is a 2003 Saturn Vue with a V6 and FWD, it runs great so far, but if this issue goes it sounds like it will be junk. Any ideas that could help fix this?
