Engineered For Efficiency With A Purpose Built Design

The ATS 310-900-2000 cooler kit is built for diesel owners who expect their truck to perform under pressure without compromise. It includes a high-efficiency transmission oil cooler paired with a fan-forced design that activates only when needed, thanks to an integrated thermostat system. This means you get precise temperature control without constantly running the fan or drawing unnecessary power. Designed for use with 1/2 inch lines, this kit includes all the necessary fittings, a thermostat kit, and a durable mounting bracket to make installation straightforward and reliable. The reversible fan can be configured for push or pull operation depending on your layout, offering excellent flexibility for custom or space-constrained builds. It’s particularly well suited for high-load scenarios like towing, off-road recovery, or stop-and-go traffic where transmission temps can spike quickly. By keeping fluid cooler, it helps prevent internal component wear, improves shift quality, and extends the overall life of the transmission. This is not just an add-on, it’s a precision upgrade for trucks that are built to work hard.
