-6 AN To 1/4NPS Transmission Cooler Adapter Fittings For GM 4L80E 1997-2007

Calling all GM 4L80E transmission owners! These -6 AN to 1/4NPS adapter fittings are exactly what you need for your transmission cooler lines. Specifically designed for 1997 through November 28, 2007 GM 4L80E transmissions, these aluminum alloy fittings provide the perfect connection between your transmission and cooler lines. The -6 AN x 1/4 NPS thread size is correct for most GM 4L80E applications, but definitely measure your factory fittings to be sure - these measure 0.520 inches across the 1/4 NPS threads. The package includes both a short and long fitting to accommodate different installation needs. The black aluminum alloy construction is both durable and corrosion-resistant, ensuring long-lasting performance under your vehicle. These aren't cheap plastic or weak metal fittings - they're precision-machined to provide a secure, leak-free connection for your transmission fluid lines. Proper transmission cooling is crucial for longevity, especially if you're towing, racing, or driving in hot conditions. The AN to NPS conversion allows you to use modern AN-style transmission cooler lines with your factory transmission ports. The installation is straightforward if you're comfortable working on transmission components, though we recommend consulting a professional if you're unsure. The precise threading ensures a tight seal without cross-threading or leakage issues that can plague inferior fittings. Having the right adapters makes transmission cooler line upgrades or repairs much simpler and more reliable. The aluminum material is strong enough to handle transmission fluid pressure and temperature variations without failing. The black finish isn't just for looks - it provides additional corrosion resistance compared to bare aluminum. Whether you're building a performance vehicle, repairing existing cooler lines, or upgrading your transmission cooling system, having the correct adapters is essential. The package including both short and long versions gives you flexibility for different clearance situations in your vehicle's undercarriage. Don't risk transmission damage from inadequate cooling or leaky fittings - use the proper adapters designed specifically for your application. The quality machining is evident in the clean threads and precise dimensions that match OEM specifications. For such a small component, having the right transmission cooler fittings can make a huge difference in reliability and performance. If you're working on your GM 4L80E transmission cooling system, these adapters are a must-have for a professional, leak-free installation that will stand up to the demands of your vehicle!
