  • Maintains Optimal Transmission Temperature: This direct-fit bypass plug eliminates the stock thermal bypass valve, ensuring transmission fluid is always cooled. This promotes a consistently lower operating temperature, extending transmission lifespan and preventing costly repairs.
  • Precision CNC Machined for Perfect Fit: Crafted from high-quality T6061 aircraft-grade aluminum with precision CNC machining, this barbell guarantees a secure, leak-free connection into the stock cooler line housing, meeting or exceeding OEM standards.
  • Simple Plug-and-Play Installation: Designed as a direct replacement for a hassle-free upgrade. No professional tools are needed. For best results, clean the housing and apply transmission fluid to the included Buna O-rings during installation.
  • Enhanced Durability & Reusability: The robust aluminum construction is built to last. The serviceable Buna O-rings provide excellent sealing and corrosion resistance, and can be easily replaced if needed, offering long-term value.
  • Specific GM Vehicle Compatibility: Engineered for GM vehicles equipped with 6L80, 6L90, and 8L90 transmissions. Please verify your transmission model before purchase to ensure a correct fit for your GMC, Chevrolet, or Cadillac.
