yeah I hear ya w/ the tranny lines. mine had a small crack and all of the tranny fluid eventually leaked out of it. not good at all.
anyways, I had to replace that whole line also. costed me about the same price that everyone else here is saying. it's too bad that you cant replace just the rubber hose and not having to replace the whole line
