AUTO TRANS COOLER LINES-RADAKOOL

Ensure your GM automatic transmission runs smoothly and at the right temperatures with high-quality transmission cooler lines from Advance Adapters. This transmission tubing is essential to an optimal transmission cooling system, circulating hot fluid away to the radiator and returning the cooled fluid to the transmission. This process is essential not only in everyday road use but in off-roading and all-terrain driving.

GM Auto Transmission Coolant Lines

Advance Adapters has transmission cooler line replacements or upgrades to keep your cooling system in top condition. These transmission lines are an OEM fit for the GM TH-350, TH400 and 700R4 automatic transmissions used in dozens of vehicles from the 1960s to the 1990s. You can adapt them to other transmissions with the right fittings. Each transmission cooling line has a Teflon inner tubing and stainless steel braided outer cover to protect against rust, punctures, cracks and wear. Durable pre-crimped hose ends and fittings are included for easy installation. The lines are seven feet long, allowing them to reach the transmission comfortably without excess slack.

A set of aftermarket Radakool transmission cooler lines is an affordable way to replace broken factory lines or upgrade as part of drivetrain conversions and custom off-road builds. Check the "Specifications" tab to confirm compatibility with your transmission before ordering.
