Transmission Tunnels

The transmission tunnel is a critical structural component of your vehicle's floor pan, providing clearance for the transmission and driveline while maintaining chassis rigidity. Over time, these tunnels can rust, crack, or require modification to accommodate larger transmissions or custom drivetrains.

Our transmission tunnel collection includes replacement panels and customization options for a variety of applications. Whether you're restoring a classic muscle car, building a custom hot rod, or simply repairing collision damage, we have the sheet metal you need.

  • Replaces worn, rusted, or damaged factory transmission tunnels
  • Available in different material gauges and finishes to match your project
  • Options may include direct-fit OEM-style panels or universal weld-in sections

Not sure which tunnel is right for your build? Check the product specifications for measurements and compatibility details. If you need help selecting the correct part, our team of automotive specialists is here to assist.
