The vast majority of automatic transmission failures are a direct result of overheating. Because your transmission relies solely on the transmission fluid to keep it cool, you need to ensure that the fluid is always at the optimum temperature. Even a relatively small drop in fluid temperature can almost double the life of your transmission and will increase its performance.
Most factory cooling systems are adequate at best, rarely causing your fluid to reach even an appropriate temperature, let alone the ideal operating temperature range of 160 to 200 degrees. If you have a modified engine, or if you often tow with your vehicle, then reaching that optimum range can be even more difficult because your system is likely being overtaxed.
A supplemental cooling system can work to ensure that proper temperatures are maintained so that your vehicle's transmission functions at its best.
The heat exchanger is the cooler itself, the core that works to maintain proper fluid temperatures. There are three basic types of heat exchangers.
The cooler kits are designed to be mounted flush against either the radiator or the AC condenser core. For maximum cooling ability, the heat exchanger must receive the most airflow possible.
Mount cooler between your vehicle's grille and the AC condenser core for the greatest efficiency.
Mounting the cooler between the condenser and the radiator still allows for ample airflow, but cuts effectiveness by 25 percent. Installation of a larger cooler unit in this position may help make up for that loss.
Mounting the cooler between your engine and radiator considerably decreases the available airflow and causes the cooler to be 40 percent less efficient than if mounted in Position A. It is recommended that you purchase a larger cooler to make up for that loss if using in Position C.
Absolutely. Most of Derale's coolers can be used not only for transmissions, but for engine oil, power steering and fuel systems as well. A power steering cooler will extend the life of both the pump and seal, drastically reducing heat-related pump failures. Installation for power steering and fuel systems requires only the heat-exchanger core and basic accessories.
