      Description

      Enhanced Transmission Cooling. The Mishimoto Full-Flow Transmission Thermal Bypass Valve Kit improves transmission fluid cooling by replacing the internal thermostat with a fully-serviceable thermostat and a bypass option. This design allows for fast warm-up in cold climates and full flow to the transmission cooler in warm climates, helping prevent transmission overheating and extending the lifespan of your vehicle's transmission system.

      Durable CNC Construction. Crafted from billet aluminum with precise CNC machining, this valve features integrated heat-sink fins for increased heat dissipation. It is finished with a black anodized coating, ensuring long-lasting corrosion resistance and a premium appearance.

      Simple Installation. The kit installs easily with minimal effort and requires no drilling or modification to stock transmission cooler piping. Most users can complete installation in under an hour.

      Lifetime Warranty. This product is backed by a comprehensive lifetime warranty covering the life of the vehicle.

      Application. Specifically engineered to fit the 2017-2019 Chevrolet Silverado 2500 HD equipped with the 6.6L Duramax L5P engine and Allison automatic transmission. Not recommended for cold climates when the thermostat bypass is installed to avoid overcooling of the transmission fluid.
