The #1 cause of automatic transmission failures is overheated transmission fluid. Today's cars generate extremely high under-the-hood temperatures. Add to that the heat generated by an automatic transmission, and you'll see why adding an auxiliary transmission oil cooler is a must for guarding against costly transmission repair.
Automatic transmission fluid cools, lubricates and cleans transmission components. A transmission cooler is basically an auxiliary radiator that provides extra cooling for automatic transmission fluid. When transmission temperatures exceed 200° F, transmission fluid is strained to its limit. Overheated fluid won't properly protect transmission seals and moving parts. When oil temperatures exceed 200° F, oil breaks down, causing seals to crack and leaks to occur.
Many owner's manuals now point out the need for a transmission cooler when towing. In fact, some owner's manuals recommend a cooler if you plan to regularly drive with additional occupants (carpool for instance).
Protect yourself from a costly transmission repair bill with a U-Haul transmission cooler. Each 20° drop in temperature doubles oil and equipment life, thereby extending the life of your vehicle. U-Haul transmission coolers constantly swirl, agitate and cool oil as it flows, to provide maximum heat dissipation and are pressure tested to ensure reliability and durability.
