2007-2013 Silverado & GMC 1500 5.3L Transmission Coolers

Your 2007-2013 Silverado or Sierra 1500 5.3L is capable, but it can get really hot when pushing it hard. All that heat isn't great for your truck's transmission and can lead to limp modes or complete failure. Tier One's lineup of 2007-2013 Silverado & Sierra 1500 5.3L transmission coolers will help keep your truck's transmission in a safe temperature 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. 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 2007-2013 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 2007-2013 Silverado & Sierra 1500 5.3L Torque Converters. You can further improve fluid flow and shift quality by installing one of our 2007-2013 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 2007-2013 Silverado & Sierra 1500 5.3L Transmission Parts.
