Transmission Fluid Thermal Bypass Valve For GM Trucks/SUVs 2014-2018 With 6L80 6-Speed - Replaces 125068000 (5.3L, 6.2L, 4.3L)

About This Product

Own a GM truck or SUV with the 6L80 6-speed automatic transmission? This thermal bypass valve helps regulate transmission fluid temperature for optimal performance and longevity. When the fluid is cold, it bypasses the cooler to warm up faster; once warm, it directs fluid through the cooler to prevent overheating.

Replaces OEM part number 125068000. Fits 2014-2018 models of Chevrolet Silverado 1500, Tahoe, Suburban; GMC Sierra 1500, Yukon; Cadillac Escalade with 4.3L, 5.3L, or 6.2L engines paired with the 6L80 transmission. Always verify your vehicle details before ordering.

Made from billet aluminum with corrosion resistance and includes a neodymium magnet to catch metal particles, plus an O-ring seal to prevent leaks. A well-designed upgrade or direct replacement for the factory valve.

If you’re experiencing transmission overheating, slow warm-up in cold weather, or just want to improve cooling efficiency, this valve can help. Installation requires some mechanical skill—drain transmission fluid, remove the old valve, and install this one. Consider having a trusted mechanic do the job if you’re not comfortable.

Keep your transmission running cooler and smoother. Especially useful for towing, hauling, or driving in extreme temperatures. A small part with a big impact on drivetrain health.

Note: Includes one valve with magnet and O-ring. Always use new transmission fluid and a new filter when servicing. Protect your investment!
