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 our 2003?2009 Dodge Ram Cummins 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 warmup 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.<br><br>PURCHASE INCLUDES<br>(1) Mishimoto Stacked-Plate Transmission Cooler<br>(2) High-Pressure Transmission Cooler Lines<br>(1) Removable Thermostat<br>(1) Removable Thermostat Bypass<br>(2) CNC-Machined Stainless Steel Barbed Fittings<br>(2) CNC-Machined Aluminum 3/4"-16 ORB to Hose Barb Fittings<br>(6) Worm Gear Clamps<br>Mishimoto Lifetime Warranty<br>Eliminates corrosion-prone quick-disconnect fittings<br>Available -8ORB to -8AN adapters allow the use of AN transmission fluid lines.
