If the dealer can't get 1306839 anymore, I'd try the 240 salvage specialists and eBay with that part number, since plenty of 240s are still being parted out. Plan B is taking your old line to a hydraulic hose shop. They can make up a new one with the right flare fittings, or do a steel section with high pressure trans cooler hose in the middle.I am looking for the 2 steel tubes that go from transmission to the radiator these are no longer available from Volvo
