Product Description
The BD DIESEL 1030606-DS-58 Xtrude Transmission Cooler with Fan is a high-performance auxiliary cooler designed to dramatically reduce transmission fluid temperatures on heavy-duty trucks equipped with 5/8 inch cooler lines. Featuring a double-stacked, micro-extruded core and a powerful thermostatically controlled 800 CFM electric fan, this complete kit delivers superior cooling capacity and reliability for Silverado/Sierra diesel applications.
Built with large surface area micro-extruded passages and turbulent oil flow design, the Xtrude double core cooler offers over 350 % greater temperature drop versus the factory transmission cooler system. The included fan automatically activates via a built-in thermostat, helping maintain optimal transmission fluid temperatures under heavy load, towing, or performance use.

FAQ
What makes this cooler more effective than stock?
The double-stacked, micro-extruded cores provide much more cooling surface area than factory coolers, leading to significantly lower transmission oil temperatures under load.
Does the fan run all the time?
No — the thermostatically controlled fan only engages when transmission fluid temperatures exceed its temperature threshold, helping keep temps in check without unnecessary power draw.
Is this a standalone cooler?
No — this kit is designed to supplement your factory cooler, not replace it. It’s intended to work alongside stock systems for maximum cooling performance.
