Specifically designed for vehicles operating in temperatures below \u003cstrong\u003e32¡F (0¡C)\u003c\/strong\u003e, this bypass valve ensures your transmission fluid reaches its optimal operating temperature as quickly as possible. In cold weather, transmission fluid becomes thick and viscous, which can lead to poor lubrication and increased wear. This assembly allows the fluid to bypass the external cooler until it warms up, protecting your drivetrain and improving shifting performance in winter conditions.\u003c\/p\u003e\n\u003cp\u003eThe Tru-Cool 4739P6 is a high-precision thermal valve that remains closed when the fluid is cold, directing it back to the transmission. As the fluid temperature reaches approximately \u003cstrong\u003e180¡F\u003c\/strong\u003e, the bypass begins to open, and it is fully open by \u003cstrong\u003e205¡F\u003c\/strong\u003e, allowing the external cooler to perform its job during high-stress or high-temperature operation. Engineered by Long Manufacturing, this \"no-fail\" component is the perfect insurance for heavy-duty trucks, towing rigs, and performance vehicles that see year-round use.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCold Weather Optimization:\u003c\/strong\u003e Essential for vehicles in climates reaching 32¡F and below to prevent fluid thickening and lubrication lag.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRapid Warm-Up:\u003c\/strong\u003e Directs cold fluid away from the cooler, allowing the transmission to reach efficient operating temperatures faster.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eThermal Precision:\u003c\/strong\u003e Starts activating at 180¡F and provides full cooling flow by 205¡F for balanced thermal management.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eUniversal Compatibility:\u003c\/strong\u003e Designed to work with any external transmission cooler using 5\/16\", 3\/8\", or 11\/32\" fluid lines.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eReliable Performance:\u003c\/strong\u003e A passive, mechanical design with no electronics to fail, ensuring consistent operation in the harshest environments.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDurable Construction:\u003c\/strong\u003e Built by Long Manufacturing (Tru-Cool) to meet rigorous performance and off-road standards.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEasy Installation:\u003c\/strong\u003e Slices into existing cooler lines, making it a simple but effective upgrade for any auxiliary cooling system.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpec\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Tru-Cool (Long Manufacturing)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 708-4739P6 \/ 4739P6\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eActivation Temp:\u003c\/strong\u003e Starts at 180¡F (Fully open at 205¡F)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLine Size Compatibility:\u003c\/strong\u003e 5\/16\", 3\/8\", and 11\/32\" Lines\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOperating Range:\u003c\/strong\u003e Optimized for sub-32¡F (0¡C) environments\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e External Thermal Bypass Valve\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Universal for Automatic Transmissions\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Trucool","offers":[{"title":"Default Title","offer_id":46137948471484,"sku":"SKU-2026200288","price":480.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0752\/4473\/2604\/files\/sku288.webp?v=1774981213","url":"https:\/\/4wk.ae\/products\/tru-cool-transmission-oil-cooler-cold-weather-thermostat-universal-fit","provider":"4WK | 4Wheel Kingdom","version":"1.0","type":"link"}
