The Mishimoto transmission cooler for the 2003-2009 Dodge Ram 2500/3500 5.9L and 6.7L Cummins is a direct-fit, stacked-plate upgrade with a massive 212% greater core volume and 244% greater fluid capacity than the stock cooler. It also solves a common failure point: where the factory thermostat fails closed and returns hot fluid to the transmission, Mishimoto's thermostat is fully serviceable through a port at the top of the cooler and can be easily bypassed for constant cooling. Replacement thermostats are available separately.
