Ensure your Dodge Ram 2003-2009 5.9L or 6.7L Cummins transmission stays cool under demanding conditions with the Mishimoto transmission cooler. Designed as a direct-fit replacement, this cooler features a stacked plate core that provides durable and efficient cooling performance. The significantly increased core volume and fluid capacity—212% and 244% respectively—make it a substantial upgrade over the stock cooler, helping to prevent overheating during towing, heavy hauling, or daily driving. This enhanced cooling capacity extends the lifespan of your transmission and improves overall vehicle reliability.
Unlike stock coolers, which can fail by bypassing hot fluid back to the transmission when the thermostat fails closed, the Mishimoto cooler is built with a fully serviceable thermostat. A conveniently located port at the top of the cooler allows for quick inspection or replacement of the thermostat, ensuring continuous cooling performance without the risk of bypass. The design simplifies maintenance and helps maintain optimal operating temperatures, even during intense workloads or extended towing sessions.
This transmission cooler is compatible with a broad range of Dodge Ram models from 2006 to 2009, including 2500 and 3500 series trucks. Its robust build and efficient cooling capacity make it a reliable choice for fleet operators, towing enthusiasts, or anyone looking to enhance their truck’s transmission cooling system. Proper installation ensures your vehicle maintains ideal operating temperatures, reducing wear and prolonging transmission life. The Mishimoto transmission cooler conforms to environmental standards and features a durable construction suitable for demanding driving conditions, backed by Mishimoto’s reputation for quality automotive parts.
