Built for workshops and performance builds, the assembly focuses on durability, leak resistance and easy routing through engine bays. The stainless braid and 6AN adapters make the kit compatible with a wide range of classic and modern automatic gearboxes while offering improved heat-shedding capacity compared with many stock rubber lines.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this kit affect transmission cooling performance?\u003c\/h3\u003e\n\u003cp\u003eThe larger 6AN diameter and longer 70\" hose length increase fluid flow and surface area exposed to ambient air, helping transmission fluid shed heat faster during heavy use.
