Leaking trans line on Jeep

You will not know the answer until you look at it. If it has just one small area where the metal line is leaking then cut out the bad part and put rubber trans cooler hose (not fuel hose) on it and clamp it. If it is really rough looking the replace the metal lines. It won't get any better on its own, only worse.

It's warmer if you do it with the engine running. A little messy, though. O:)
