Transmission Fluid Cooler Leaks at Radiator
WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
Transmission fluid may leak between the radiator transmission fluid cooler and the transmission fluid cooler fitting (not the cooler line into the fitting), which may result in a residue of transmission fluid on the radiator tank around the fluid cooler fitting. Insufficient thread sealer on the transmission fluid cooler fitting may cause this.
