My mother N Law has an 89 tarus wagon with the 3.0 motor. I just replaced the Radiator in the car and now I can't get that top tranny line to stop leaking. It isn't coming out the threads, just out the back of the flare nut were the medal line goes in. There appears to be a plastic clip on the inside. Does anybody know how to take this apart if possible and/or I can fix this without replacing the hole line.
