4454 LPD Transmission Cooler

The Tru-Cool 4454 is a Low Pressure Drop (LPD) transmission cooler engineered to enhance the longevity and performance of automatic transmissions, especially under demanding conditions such as towing, heavy hauling, or stop-and-go traffic. This cooler is built with quality hardware and includes necessary hose for a complete installation. With a BTU rating of 13,000, the 4454 is designed to effectively manage transmission fluid temperatures, supporting vehicles with a Gross Vehicle Weight Rating (GVWR) of up to 18,000 lbs. The manufacturer, Tru-Cool, is known as an original designer of Low Pressure Drop Technology, a feature adopted by many factory transmission coolers. Users have found the included hardware and hose to be suitable for various applications, with recommendations to securely bolt the cooler in place using the supplied metal brackets rather than zip ties. Proper transmission fluid temperature is crucial; temperatures between 160-200°F are considered normal. Exceeding normal temperatures significantly accelerates fluid oxidation, drastically reducing its lifespan and potentially causing damage to transmission components. This cooler helps maintain optimal operating temperatures, thereby preserving fluid integrity and extending transmission life. The Tru-Cool 4454 is an add-on transmission cooler and is not designed as a direct replacement for the original equipment (OE) cooler. It is recommended to check Tru-Cool's website for GVW ratings to ensure the selected cooler is appropriate for your specific towing or hauling needs.
