Special Features

  • "1. 【Compatible with 5/16"" and 3/8"" Transmission Cooler Lines】 Designed for universal inline installation, this external thermal bypass valve fits transmission coolers with 5/16-inch or 3/8-inch fluid lines. Ideal for most aftermarket cooler systems requiring bypass functionality. "
  • "2. 【Optimized for Cold Climate Operation】 Provides smoother cold starts by bypassing the cooler when transmission fluid is cold (approx. below 180°F). Ideal for vehicles operating in below-freezing environments, helping maintain proper pressure and warm-up behavior."
  • "3. 【Stand-Alone or Add-On Use】 This component can be added to existing cooler systems such as those similar in configuration to the 47391 series. Note: This bypass valve is already included in some complete cooler kits."
  • "4. 【Durable Inline Design for Reliable Performance】 The thermal valve body is built for continuous fluid flow and thermal control, using robust materials to ensure long-lasting operation under temperature cycling and pressure fluctuations."
  • "5. 【Brand Assurance】 Enjoy a 1-year warranty and dedicated after-sales support. At Gagsu, we are committed to making your shopping experience enjoyable—feel free to contact us for any assistance."
