I have developed a fluid leak where the rubber meets the metal on the upper transmission line on the drivers side that runs under the breather filter from motor to air filter.
Transmission Lines started leaking after I had brake lines, fuel lines and radiator replaced. Transmission fluid puddles under RF fender. I hate this car!
