2014-2018 Silverado & Sierra 1500 5.3L Transmission Coolers

The 2014-2018 Silverado and Sierra 1500 5.3L trucks are capable, but they run notoriously hot due to the factory thermal bypass valve, which restricts cooler flow. Tier One's selection of transmission coolers and bypass upgrades helps keep your transmission temperatures under control and in a safe operating range. We offer thermal bypass valves that ensure full-time cooling flow, as well as high-efficiency auxiliary coolers that shed heat much faster than the stock unit. These upgrades are essential for preventing fluid breakdown and torque converter failure. If your truck has already suffered from heat damage and is slipping in gear, a cooler alone won't fix the internal clutches, so you may need to look at replacing the unit with one of our 2014-2018 Silverado & Sierra 1500 5.3L Complete Transmissions. An unlocking torque converter creates significant friction and heat, so to reduce heat generation at the source while improving towing performance, consider upgrading to one of our 2014-2018 Silverado & Sierra 1500 5.3L Torque Converters. You can further improve fluid flow and shift quality by installing one of our 2014-2018 Silverado & Sierra 1500 5.3L Valve Bodies. Another great way to help manage heat is by increasing your overall fluid volume with a deep pan from our section of 2014-2018 Silverado & Sierra 1500 5.3L Transmission Parts.
