  • 1 - High-quality OE style direct replacement Allison transmission cooler.

Tech Tip: Does your truck have higher mileage and higher than normal transmission temps? Its probably time to freshen up the Transmission cooler. Over time the stock torque converter and internal clutch material can plug your trans cooler and reduce its cooling capabilities. We highly recommend our new OE or performance transmission cooler anytime you rebuild or upgrade your transmission. This will insure transmission efficiency and longevity.

DmaxStore Note: When replacing the transmission cooler, you will lose about 1-2 quarts of transmission fluid. We recommend using Transynd Transmission Fluid
