Product Details

The Mishimoto MMTCL-DMAX-06 Transmission Cooler Line Kit is engineered to provide superior durability and performance for 2006-2010 Chevrolet and GMC 6.6L Duramax diesel trucks equipped with LLY, LBZ, and LMM engines. This direct-fit replacement kit eliminates the weak points of factory rubber lines with high-strength braided construction designed to handle the demanding conditions of heavy-duty towing and performance applications.

Key Features:

  • Direct bolt-on replacement for 2006-2010 Duramax LLY, LBZ, and LMM engines—no modifications required
  • High-flow -10AN lines and fittings maximize transmission fluid flow while preventing leaks
  • Extreme pressure rating with 2,000 psi working pressure and 6,000 psi burst pressure
  • High-strength nylon outer braid resists expansion under pressure and protects against abrasion and heat
  • Backed by Mishimoto's Lifetime Warranty for long-term peace of mind

This transmission cooler line kit is ideal for truck owners looking to upgrade from failure-prone factory lines or restore proper transmission cooling performance. The braided stainless steel construction with nylon outer protection ensures reliable operation even under the most demanding towing and performance conditions.
