The Mishimoto transmission cooler for the 1994-2002 Dodge Ram 2500/3500 5.9L Cummins is a direct-fit, tube-and-fin upgrade that lowers fluid temperatures for towing, fleet, and daily-driven 2nd-gen trucks. It delivers 116% greater core volume, a 141% increase in fluid capacity, and 134% greater fin surface area than the stock cooler. Because the factory quick-disconnect fittings often seize, Mishimoto includes two CNC-machined stainless steel hose-barb fittings and transmission hose so you can bypass the old fittings and connect the stock soft-line directly to the cooler.
