The BD Diesel Xtrude double‑stacked auxiliary transmission cooler (cooler assembly only) delivers high cooling capacity with over 40,000 BTU/hr and substantial temperature drop versus factory units. Double stacked cores and 200 micro extruded passages increase surface area for effective heat transfer. The assembly uses large 5/8‑inch ports to avoid restrictions, furnace‑brazed rails rated to 300 psi and an IP54 motor with an 80‑watt, 10" 800 CFM fan for thermostatic automatic oil temperature control.
