Transmission Cooler Line Set, 3/8" 3-Piece

The LinesToGo transmission cooler line set offers a direct-fit solution for your 2006 Chevrolet Silverado C/K 1500 equipped with the 5.3L engine and HD Cooling (RPO Code KNP). This set is specifically designed to exclude vehicles with the 4L80-E transmission (exc. RPO Code MT1), ensuring proper fitment for compatible models. Constructed with durability in mind, the lines feature Galfan® coated tubing for superior rust protection. This tubing is CNC (Computer Numerically Controlled) bent to match original equipment end forms, guaranteeing an easy and precise installation. The hoses themselves are made from robust Stainless Steel Braided Teflon and are equipped with OE-style fittings, ensuring reliable performance and longevity. This set includes three 3/8" lines: the upper inlet line (provided in two easy-to-install sections), the lower outlet line, and the auxiliary cooler outlet line. Installation is straightforward, with detailed instructions and videos available to guide you through the process. The lines connect from the upper radiator to the passenger side of the auxiliary cooler, the lower radiator to the lower transmission, and the auxiliary cooler outlet to the upper transmission.
