Mishimoto 01-05 Chevrolet/GMC 6.6L Duramax (LB7/LLY) Transmission Cooler Line Kit

When you're pushing your 6.6L Duramax engine, especially the LB7 or LLY models found in 2001-2005 Chevrolet Silverado 2500 HD and 3500 trucks, keeping the transmission cool is just as important as keeping the engine cool. This transmission cooler line kit from Mishimoto is built to handle the demands of a hard-working truck. It features a PTFE inner liner that's really resistant to oil and heat, making sure the fluid can flow reliably even in tough conditions.

To handle the higher line pressures that can come with performance transmissions or heavy towing, these lines are wrapped in a strong nylon braid. This wrap prevents the lines from expanding under pressure and also protects them from abrasion, which is a common issue in the undercarriage. The lines are finished off with secure -10AN fittings, ensuring a leak-free connection to your transmission cooler setup. This kit is a solid option for anyone looking to upgrade their cooling system and ensure their transmission stays healthy.
