Show original supplier description
The Tru-Cool OC-4454 is a high-performance stacked plate automatic transmission oil cooler engineered to maintain optimal transmission fluid temperatures, even under demanding conditions. With a substantial 18,000 lbs Gross Vehicle Weight Rating (GVWR), this cooler is ideal for trucks, towing vehicles, and other applications that frequently push their transmissions to the limit. Constructed with 36 stacked plates, the OC-4454 offers superior cooling capacity compared to traditional tube-and-fin designs. Its efficient heat exchange helps prevent transmission fluid breakdown, extending the life of your transmission and reducing the risk of costly repairs. The unit features a 11/32" hose barb for straightforward connection to your vehicle's existing fluid lines. Key specifications include a 13,000 BTU rating, indicating its robust capability for dissipating heat. The cooler's dimensions are approximately 7 1/4" x 11" x 3/4", making it a versatile fit for a wide range of vehicle installations. Some sources indicate a weight of around 4.00 lbs and other package dimensions such as 10" width and 3" height.
