I've got a 2005 Dakota (4.7) and I believe that one of my transmission line fittings is stripped on the radiator side. The connector won't thread on at all. It's the radiator side that is stripped. Threads on the male connector look to be fine. I assume this means I will need to replace the radiator? Just looking for some suggestions at this point. Also, if I do have to replace, any write-ups that folks would recommend?
