Has anyone replaced the transmission cooler line that has the rubber portion? The entire line bolts to the top of the radiator and has a rubber segment near the bottom of the radiator that looks like it should be replaceable. Is this something that I should attempt, or is it best left to a transmission specialist or professional mechanic. Any information on the replacement of the line would be appreciated. Mine on my 2003 Grand Cherokee Laredo QTII (4.0L) is leaking.
