The BD Diesel 1030606-5/8 inch transmission oil cooler is engineered for heavy-duty diesel applications, providing enhanced cooling capacity and reliable performance under severe operating conditions. Designed specifically for models like the 2010 GMC Sierra 2500 HD and 3500 HD, this cooler features a robust extruded core with 200 micro passages that promote turbulent oil flow for more effective heat transfer. The large 5/8-inch ports ensure minimal inlet and outlet restrictions, facilitating increased oil volume flow and improved cooling efficiency. This design helps maintain optimal transmission fluid temperatures, extending component life and ensuring consistent operation during towing, hauling, or high-performance driving.
The cooler assembly includes a galvanized bracket kit for easy installation, eliminating the need for custom fabrication. The pre-wired harness with fuse and relay provides a straightforward connection, while the thermostatically controlled 80-watt, 10-inch electric fan with an 800 CFM airflow rating offers active cooling when needed. The fan’s thermostatic control ensures it operates only when necessary, reducing electrical load and noise. Furnace-brazed rails withstand pressures up to 300 psi, ensuring durability in demanding environments. All fittings, clamps, hoses, and hardware are included for a complete installation. The turbulent oil flow design, combined with large surface area and high airflow capacity, delivers 22% more cooling efficiency compared to conventional designs, preventing heat soak and reducing operating temperatures to improve transmission longevity.
Built to meet the demands of fleet and heavy-duty trucks, this cooler supports vehicles with a gross vehicle weight of over 30,000 pounds and is rated for 33,930 BTU per hour. It is suitable for use with Chevy Allison 1000 transmissions and is constructed to meet rigorous standards, including the Prop 65 requirement. Backed by a 12-month or 24,000-mile warranty, the BD Diesel extruded transmission oil cooler ensures long-term reliability and optimal transmission performance in demanding driving conditions.
