BD Diesel Transmission Cooler Bypass Valve Delete Kits

BD Diesel has been a leader in heavy-duty powertrain components since 1972. They focus on getting the most power and durability out of your diesel-powered truck—and to help eliminate costly transmission failure, they offer these transmission cooler bypass valve delete kits. The factory cooler valve can be stuck in recirculation mode if any type of debris jams the internal valve; this will increase temperatures dramatically and cause transmission failure. These cooler bypass delete valves always keep transmission fluid flowing to the cooler regardless of speed or load of the truck—ensuring your transmission will stay cool and eliminate costly repairs. Look to BD Diesel to push your truck to be all it can and should be. Order the kit recommended for your vehicle, engine, and transmission application.
