I've got a 2006 Expedition, with the 5.4L and heavy duty towing package. The transmission cooler lines have rusted out. My mechanic is trying to replace them and is having problems. The connectors to both the transmission cooler and the radiator are so rusted that the connectors are breaking. He says that if he could get the fittings to connect to the bottom of the radiator and the cooler he could just replace those, but Ford doesn't sell them separately. Unless I can find these fitting I'm looking at a new transmission cooler and radiator. Does anyone know of an after market company that might sell these fittings? Any other suggestions?

PS: I'm no mechanic myself (I'd much rather work in a computer) so please type slowly!!

Thanks for any advice
