Any time you replace an automatic transmission you're doing so because you smoked the last one. Usually it's because you overheated the fluid from towing, engine upgrades, or running large tires. In our case it was all three. To protect our new transmission from fluid failure, we ordered the largest ATF cooler we could get from Flex-a-lite. This 32,000-pound-GVW unit (PN 45321) measures 10 1/2x21x1 1/2 inches. We plan to fit it where the factory auxiliary cooler mounted and adapt the original Ford cooler lines to work with its 1/2-female NPT fittings.
