Product Information

The Mishimoto transmission cooler line kit for the 2001-2005 Chevrolet/GMC 6.6L Duramax LB7/LLY routes transmission fluid to the cooler with high-performance PTFE lines wrapped in a high-strength nylon braid. The PTFE inner liner is highly oil- and heat-resistant, while the braid prevents expansion under pressure and resists abrasion. Capped with -10AN fittings for a secure, leak-free connection, the lines carry a 2,000 psi working pressure and 6,000 psi burst rating, ideal alongside a performance transmission cooler.
