Product Details
✓[Improved 6L80 Cooler Flow] This 6L80 transmission thermal bypass valve improves fluid flow to the cooler, helping manage heat during towing, heavy loads, stop-and-go traffic, and hot-weather driving while supporting stable transmission performance.
✓[Replacement for OE 125068000] Designed as a 6L80 thermostat bypass kit for compatible 2014-2018 applications. Factory-style connections support straightforward replacement without cutting cooler lines or modifying the transmission.
✓[Durable Metal Construction] Precision-machined aluminum alloy and machined steel resist heat, corrosion, and wear. The solid metal design is built for demanding under-vehicle conditions and repeated transmission heat cycles.
✓[Serviceable Magnetic Plug] The integrated neodymium magnet helps capture ferrous wear particles in the transmission fluid. The removable service plug can be inspected and cleaned during routine maintenance for an added debris check.
✓[Verify Fitment Before Purchase] Compatible with select 2014-2018 Chevrolet Silverado 1500/Tahoe, GMC Sierra 1500/Yukon, and Cadillac Escalade models with the 6L80 6-speed transmission. Confirm OE 125068000 and cooler-line style before purchase.
