It's responsible for transmitting large quantities of torque from your V8 diesel powerplant. This torque generates a lot of heat, and if that heat isn't dissipated, it can destroy your transmission. The transmission cooler does a good job of keeping trans fluid temperatures in check, but only if the fluid can reach it. The stock cooling system of the Allison 1000 transmission utilizes an in-line thermal bypass valve that controls fluid flow to the transmission cooler. The purpose of this valve is to prevent transmission fluid from flowing to the cooler until it reaches operating temperature. The thermostat inside this valve is prone to failure, however, and when that happens, the fluid never flows to the cooler, and the transmission can overheat. That's why Mishimoto has developed a full-flow thermal bypass valve upgrade for your 2017-2019 Chevrolet\/GMC 6.6L Duramax. Our CNC-machined aluminum full-flow thermal bypass valve not only looks better than the stock unit, but it performs better too. This Mishimoto thermal bypass valve eliminates the internal thermostat, providing full fluid flow to the transmission cooler in all running conditions. This setup is ideal for owners in warm climates, those performing heavy towing, and trucks needing the best possible cooling efficiency for their transmission. The Mishimoto thermal bypass valve features strategically machined internal passages, providing improved flow over the stock valve for more effective cooling. In addition, cooling fins machined into the valve body adds even more heat dissipation. This 2017-2019 Chevrolet\/GMC 6.6L Duramax L5P Full-Flow Thermal Bypass Valve Kit is built to last a lifetime with a durable black anodized finish and our Mishimoto Lifetime Warranty.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cli\u003eDirect fit for 2017-2019 Chevrolet\/GMC 6.6L Duramax L5P\n\u003c\/li\u003e\u003cli\u003eInstalls in less than 1 hour\n\u003c\/li\u003e\u003cli\u003eEliminates failure-prone bypass valve\n\u003c\/li\u003e\u003cli\u003eDurable CNC-machined billet-aluminum construction\n\u003c\/li\u003e\u003cli\u003eFull-flow bypass allows the transmission cooler to operate at maximum efficiency\n\u003c\/li\u003e\u003cli\u003eHelps extend transmission life and prevent overheating\n\u003c\/li\u003e\u003cli\u003eFits with stock transmission cooler piping, requiring no modification for installation\n\u003c\/li\u003e\u003cli\u003eIntegrated heat-sink fins provide unique styling and added heat dissipation\n\u003c\/li\u003e\u003cli\u003eDurable anodized finish\u003c\/li\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Includes:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cli\u003e(1) CNC-Machined Billet Aluminum Thermal Bypass Valve\n\u003c\/li\u003e\u003cli\u003e(2) 7\/8-inch X 14 Quick-Disconnect Transmission Line Fittings\n\u003c\/li\u003e\u003cli\u003e(1) Transmission Line Mounting Plate\n\u003c\/li\u003e\u003cli\u003e(1) Transmission Line Mounting Plate Bolt\u003c\/li\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eCompatible With:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cli\u003e2017-2019 GMC Sierra 3500 HD Sierra 2500 HD 6.6L\n\u003c\/li\u003e\u003cli\u003e2017-2019 Chevrolet Silverado 2500 HD Silverado 3500 HD 6.6L\u003c\/li\u003e","brand":"Mishimoto","offers":[{"title":"Default Title","offer_id":53059732504939,"sku":"MIS-MMTC-L5P-TBVFF","price":99.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1961\/1987\/files\/MIS-MMTC-L5P-TBVFF-1.jpg?v=1775537537","url":"https:\/\/caautoparts.com\/products\/chevy-silverado-gmc-sierra-2500-3500-hd-transmission-oil-coolers-mismmtc-l5p-tbvff","provider":"CA Auto Parts","version":"1.0","type":"link"}
