Mishimoto transmission cooler line kit for 2001–2005 Chevrolet/GMC 6.6L Duramax (LB7/LLY) routes fluid to an upgraded cooler using PTFE inner lines wrapped in a high-strength nylon braid. The construction resists oil and heat, prevents expansion under high pressure, and protects against abrasion, while -10AN fittings ensure secure connections. These lines are intended to support reliable cooling for heavy-duty and performance applications.
