2014-2018 Silverado & Sierra 1500 5.3L Transmission Coolers

The 2014-2018 Silverado and Sierra 1500 5.3L trucks are more than capable of going out and towing heavy, ripping around off-road, or driving hard on the on street, but they do get pretty hot when getting pushed hard, which isn't great for your Silverado or Sierra's 6L80 or 8L90 transmission. Tier One's selection of transmission coolers for 2014-2018 Silverado & Sierra 5.3L 1500s will keep your truck's transmission temperatures under control and in a safe operating range, even when you're towing heavy or really ripping around. Each of these transmission coolers is much more effective at dissipating heat than stock, and we have both Silverado & Sierra 1500 drop-in transmission coolers and Silverado & Sierra 1500 auxiliary transmission coolers so that you can find the perfect transmission cooler option for your Silverado or Sierra build.
