Earl's – Straight Transmission Adapter -6 AN Male to 9/16-18 Threads (Short/Front)
Description

Improve clearance and simplify transmission plumbing with the Earl’s Straight Transmission Adapter, designed specifically for GM 4L80E applications using the long/rear 1/4-18 NPSM port. This high-quality steel adapter converts the factory thread to a -6AN male connection, allowing reliable integration with AN lines during engine swaps or custom builds. Its nickel-plated finish provides excellent corrosion resistance, while the direct-fit design ensures a secure, leak-free seal. By replacing restrictive factory hard lines, this adapter offers greater routing flexibility, improved clearance in tight transmission tunnels, and dependable performance in high-demand setups.

Features:

  • Direct-fit for GM 4L80E transmissions using 9/16-18 short/front threads
  • Converts factory port to -6 AN male for flexible line routing
  • Improves tunnel clearance during engine swaps
  • Steel construction with corrosion-resistant nickel finish
  • Compatible with custom and high-performance plumbing setups
  • Ideal for replacing factory hard lines with AN fittings
