      Description

      Efficiently Cool Your RAM’s Transmission. Heat is the enemy of any RAM automatic transmission, degrading the transmission fluid, reducing lubricity, and wearing critical components like clutch packs and valve bodies. Therefore, one of the best forms of protection for any automatic transmission is to maintain a cool operating temperature, most commonly accomplished with the addition of an oversized, high flow transmission cooler such as this Mishimoto Transmission Oil Cooler. 

      Premium Performance. This Mishimoto Cooler offers exceptional performance through its stacked-plate design and large form factor, exhibiting minimal pressure loss between the inlet and outlet. Additionally, this cooler features a 212-percent increase in core volume and a 244-percent increase in fluid capacity, allowing the cooler to pass over double the fluid as the OE unit for exceptional cooling performance. 

      Durable Construction. Featuring an all-aluminum construction and robust bar and plate design, this durable transmission cooler is undoubtedly up to the task of residing on your Cummins-equipped RAM. In addition, the rugged design makes this cooler highly resistant to impacts and road debris, preventing cracks and leaks. 

      Integrated Thermostat. This transmission cooler is equipped with an integrated thermostat, blocking the flow of transmission fluid to the cooler until the transmission has reached proper operating temperature. 

      Includes Everything Necessary For Installation. While this cooler is a direct bolt-on replacement as far as mourning is concerned, plumbing is a different story. This cooler requires you to cut the factory quick-disconnect ends to accept the included hose barbs from the factory lines. This kit also includes two additional lengths of oil-resistant hose and six worm-gear clamps. 

      Warranty. A limited lifetime warranty protects this product from manufacturing defects. 

      Application. This Mishimoto Transmission Oil Cooler fits all 2003-2009 RAM 2500s equipped with the 5.9L or 6.7L Cummins I6 turbo diesel engines.
