By adding more weight to your vehicle when towing, you're making its drivetrain do a lot of extra work. Extra weight leads to extra heat under the hood, which can add strain to your transmission and wear it out too quickly.
Adding a transmission cooler, especially if your tow vehicle is an automatic, will significantly reduce the temperature of the oil circulating through your vehicle's transmission. Also, simply adding a higher-capacity radiator or installing an additional cooling fan will help save you money in the long run on expensive repairs to worn-out systems.
