2022-2024 Silverado & Sierra 1500 3.0L Duramax Transmission Coolers

Your Silverado or Sierra 1500 3.0L Duramax packs a punch, but all that torque generates heat that isn't good for your 10L80 transmission. Tier One's selection of transmission coolers for 2022-2024 Silverado & Sierra 1500 3.0L Duramax trucks will keep your transmission in a safe temperature range, preventing limp mode and fluid breakdown. These coolers are much more effective at dissipating heat than stock, giving you lower transmission temperatures even when you're towing heavy or pushing your truck hard. We have both drop-in replacement coolers and auxiliary units available so that you can find the perfect setup for your truck. 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 2022-2024 Chevy & GMC 1500 3.0L Duramax 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 2022-2024 Chevy & GMC 1500 3.0L Duramax Torque Converters. You can further improve fluid flow and shift quality by installing one of our 2022-2024 Chevy & GMC 1500 3.0L Duramax Valve Bodies. Another great way to help manage heat is by increasing your overall fluid volume with a deep pan from our section of 2022-2024 Chevy & GMC 1500 3.0L Duramax Transmission Parts.
