Overview

Designed for the front (short) and rear (long) transmission line ports, this -6AN to 1/4in NPSM adapter enables connection to a dedicated transmission cooler. The threaded O.D. is 0.516 in, matching the standard GM case thread, ensuring compatibility with the GM 4L80E family.

Machined in Wichita, Kansas from aerospace-grade USA-produced billet aluminum, this adapter balances durability with precision. The bare aluminum finish is lightweight and resistant to corrosion, ideal for a clean, under-hood appearance.

Why this matters

  • Front and rear port compatibility for versatile routing
  • -6AN to 1/4in NPSM threading for AN hoses and cooler connections
  • GM 4L80E compatibility across LS/GM platforms listed
  • Precision-machined aerospace billet aluminum for a consistent fit
  • Includes O-rings for a reliable seal

Real-world use cases

In real-world installs, technicians often plumb an AN-6 line to an external cooler for improved transmission cooling, especially in performance or towing scenarios. The front (short) and rear (long) fittings support different routing paths, enabling a tidy, high-flow cooling loop. The standard GM thread size simplifies installation with common hoses and adapters.
