      Efficient. The Transmission Cooler Line Set is meticulously designed to significantly enhance the cooling efficiency of transmission fluid. It effectively reduces the operating temperature during high-load conditions, such as heavy towing or long periods of driving in hot climates. This improved cooling capability is vital for preventing the transmission fluid from overheating, which can degrade its quality and reduce performance.

      Durable. This Transmission Cooler Line Set plays a crucial role in extending the longevity of your transmission by maintaining lower transmission fluid temperatures. Cooler temperatures prevent the chemical breakdown of the fluid, which in turn reduces wear on the transmission's internal components such as gears, bearings, and seals. This maintenance of a cooler operational environment helps to prevent common issues like fluid oxidation and varnish deposits, which can lead to costly repairs.

      Installation. Putting this Transmission Cooler Line Set on your Duramax Sierra 3500 HD takes 2 hours to install.

      Application. The Transmission Cooler Line Set fits 2017-2019 6.6L Duramax Sierra 3500 HD models.
