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

Your Silverado or Sierra 1500 3.0L Duramax and its 10L80 transmission pack a whole heck of a lot of punch, allowing your tough truck to tow extremely heavy, go on off-road adventures, and tear it up on the street. That being said, the 3.0L Duramax Silverado and Sierra 1500s produce a bunch of heat, which definitely isn't good news for its 10L80 transmission. Tier One's selection for 2022-2024 Silverado & Sierra 1500 3.0L Duramax transmission coolers will keep your Silverado or Sierra's transmission in a safe temperature range, even if you're towing extremely heavy, rocking some extra power, or throwing down out on the trail. These 3.0L Duramax transmission coolers are much more effective at dissipating heat than stock, and we have both Silverado & Sierra drop-in transmission coolers and Silverado & Sierra auxiliary transmission coolers available so that you can find the perfect transmission cooling solution for your truck.
