Engineered specifically for 2013–2024 RAM 6.7L Cummins and 6.4L Hemi trucks, this upgrade replaces the failure-prone factory bypass valve assembly, ensuring continuous, unrestricted fluid flow through your transmission cooling stack at all times.\u003c\/p\u003e\n\u003cp\u003eFrom the factory, Dodge incorporated a thermal bypass valve into the cooling lines of the 68RFE, 66RFE, and Aisin AS69RC transmissions. Intended to warm up transmission fluid quickly in cold climates, the OEM valve routinely sticks, leaks, or fails in the bypass position. When this happens, transmission fluid bypasses the cooler entirely—recirculating superheated fluid directly back into the transmission. Over time, this extreme heat causes severe clutch slippage, burnt fluid, and premature transmission failure.\u003c\/p\u003e\n\u003cp\u003eThe ATS billet cooler block completely eliminates the failure-prone internal thermostatic valve, forcing 100% of your transmission fluid through the cooler circuit. The result is a dramatic drop in operating temperatures and long-term peace of mind, whether you're daily driving or pulling heavy loads.\u003c\/p\u003e\n\u003cp\u003eKey Features \u0026amp; Performance Benefits\u003cbr\u003eFull-Time Fluid Cooling: Eliminates the restrictive internal bypass valve to ensure 100% of transmission fluid is routed through the cooler.\u003cbr\u003ePrevents Thermal Damage: Significantly lowers fluid operating temperatures under heavy towing, high ambient heat, and steep grade conditions.\u003cbr\u003ePremium Billet Construction: Precision CNC-machined from high-strength billet aluminum for maximum durability, corrosion resistance, and a leak-free seal.\u003cbr\u003eSolves Factory Design Flaws: Stops the common issue of the OEM thermostat sticking closed and starving your transmission of proper cooling.\u003cbr\u003eComplete Upgrade Kit: Includes the ATS Thermal Bypass Block, robust Clamp Plate, Billet Filter Coupler, and required sealing hardware for a seamless installation.\u003cbr\u003eReplacement Hardware Available: Need extra or replacement seals down the road?

The OEM bypass valve on 2013–2024 RAM models is notorious for sticking closed, preventing fluid from ever reaching the cooler. Installing the ATS Billet Thermal Bypass Block ensures your cooling system is working 100% of the time to extend the life of your 68RFE or AS69RC transmission.\"\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eATS Thermal Bypass Valve Mounting Bracket\u003cbr\u003eFits 2019–2024 RAM 6.7L Cummins\u003cbr\u003eIf your truck is making a rattle sound or if you just looked under your truck and noticed a broken piece of metal near the thermal bypass valve, you’re most likely looking at a broken bracket that holds the thermal bypass valve securely in place. The factory brackets are thin, cheap, and subject to wearing prematurely due to the materials and finish used from the factory. If the bracket is broken on your truck, the lines vibrate with the engine, creating a weak connection at the lines and junctions that will eventually begin leaking.\u003c\/p\u003e\n\u003cp\u003eWhen this bracket breaks, the only OEM solution is to purchase an entire transmission line assembly for a few hundred dollars. Replacing that full line is a messy, time-consuming repair that leaves automatic transmission fluid (ATF) spilled on your garage floor while you try to calculate and refill the exact amount lost.\u003c\/p\u003e\n\u003cp\u003eATS has solved that hassle with the ATS Thermal Bypass Valve Mounting Bracket. Our heavy-duty bracket is made of thick 12-gauge steel and is completely corrosion resistant thanks to a high-quality zinc plating. This bracket is built to stay strong and sturdy for as long as you own the truck, holding everything firmly in place and keeping your transmission cooling system working efficiently.\u003c\/p\u003e\n\u003cp\u003eIt’s the perfect fix for true peace of mind—knowing your truck won't start rattling down the road on your next long trip or while driving down a remote washboard road. The installation is simple, and the fit and finish is just what your truck deserves to keep serving your every demand.\u003c\/p\u003e\n\u003cp\u003eKey Features \u0026amp; Benefits\u003cbr\u003eHeavy-Duty Upgrade: Built from thick, durable 12-gauge steel that outlasts fragile factory brackets.\u003cbr\u003eCorrosion Resistant: Finished with a quality zinc plating to prevent rust and degradation from harsh road conditions.\u003cbr\u003eSaves Time \u0026amp; Money: Solves the problem directly without needing to buy a costly, full OEM transmission line assembly.\u003cbr\u003eNo Messy ATF Spills: Avoids the hassle of disconnecting full transmission lines and spilling fluid on your floor.\u003cbr\u003ePrevents Leaks \u0026amp; Rattles: Locks the thermal bypass valve securely to eliminate line vibration and prevent future fluid leaks.\u003cbr\u003eSimple Bolt-On Installation: Direct-fit upgrade designed for a quick and straightforward installation.\u003c\/p\u003e","brand":"ATS Diesel Performance","offers":[{"title":"2013 - 2018","offer_id":48160807125153,"sku":"310-005-2392","price":99.99,"currency_code":"USD","in_stock":true},{"title":"2019 - 2024","offer_id":48160807157921,"sku":"310-005-2464","price":99.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0463\/5983\/8881\/files\/DSC06082.jpg?v=1792535202","url":"https:\/\/scovelmotorsports.com\/products\/ats-thermal-bypass-valve-up-grade-for-2013-2024-6-7l-cummins-6-4l-hemi","provider":"SCOVEL MOTORSPORTS","version":"1.0","type":"link"}
