Transmission cooler lines keep your 1965 or 1966 Chevy transmission pressure in check. Original lines can become crimped, restricting the tube. Rust is also a problem. Old lines can rust from the inside out or at the fittings causing leaks. All these factors can lead to pressure malfunction, and ultimately transmission damage. Our steel lines are prebent like the originals and feature the correct end fittings. Durable steel and CNC machining make these lines second to none.
