2003-2009 Transmission cooler and lines kit

Keep the transmission cool in your 2003-2009 Dodge 5.9L/6.7L Diesel with the Mishimoto MMTC-RAM-03SL Transmission Cooler. There's no greater enemy for a transmission than heat. Whether your Ram 2500/3500 is a dedicated tow vehicle, hardworking fleet truck, or a daily driver, you need to ensure that your transmission runs cool. Luckily, Mishimoto has developed a direct-fit transmission cooler to do just that. Their transmission cooler utilizes a stacked plate core for durable and powerful cooling. With a massive 212-percent greater core volume, 244-percent increase in fluid capacity, this trans cooler is a huge improvement over stock trans cooler. 

The Mishimoto transmission cooler is not only larger than the stock cooler, but more reliable too. When the stock cooler's thermostat fails, it fails closed, bypassing the cooler and returning hot fluid to the transmission. Mishimoto has solved this common issue by making the thermostat in this transmission cooler fully serviceable and easily bypassed for constant cooling. A port located at the top of the cooler provides easy access to the thermostat for servicing in just a few minutes. Replacement thermostats can be purchased individually if needed;no more replacing the entire cooler if the thermostat fails. Owners in cold climates can still enjoy the fast warm-up times that the thermostat provides, while owners in hot climates can choose to bypass the thermostat by replacing it with the supplied stainless-steel bypass plug.

To make this cooler even easier to install and service, Mishimoto saves you the hassle of removing seized fittings. The provided CNC-machined, stainless steel hose barb fittings let you cut to the chase, literally. These fittings and the supplied transmission cooler hose allow you to remove the quick-disconnect fittings and connect the stock soft-line to the Mishimoto cooler. Like all Mishimoto products, this transmission cooler is backed up by their Lifetime Warranty

• Direct-Fit Replacement
• 212% Increase In Core Volume
