2010-2012 Ram 6.7L Cummins Transmission Coolers
It's not hard to get your Ram's transmission temperatures pretty high, especially if your truck is running around with a bunch of extra power or towing extremely heavy loads. To keep your transmission cool when you're pushing your truck to the limit, your best bet is an aftermarket Ram Cummins transmission cooler from Tier One. These Ram performance transmission coolers have more surface area and more efficient designs than the factory cooler to keep temperatures down and preserve your transmission's overall lifespan. Our transmission coolers for 2010-2012 Ram 6.7L Cummins trucks are extremely easy to install and make for hassle-free performance upgrades for your aggressive Ram Cummins build.
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 2010-2012 Ram 6.7L Cummins 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 2010-2012 Ram 6.7L Cummins Torque Converters. Sometimes overheating is caused by inefficient fluid routing or cross-leaks inside the case, but you can improve fluid flow and reduce operating temperatures by installing one of our 2010-2012 Ram 6.7L Cummins Valve Bodies. Another great way to help manage heat is by increasing your overall fluid volume, so add several quarts of extra capacity and help dissipate heat by adding a deep pan from our section of 2010-2012 Ram 6.7L Cummins Transmission Parts.
About 2010-2012 Ram 6.7L Cummins Transmission Coolers
Keeping your 2010-2012 Ram's transmission temperatures under control is critical for longevity, but these specific model years suffer from a significant factory design flaw. On the 2010-2012 trucks, the transmission cooler is integrated directly into the A/C condenser. This setup leads to "heat soak," especially during the summer months; when your A/C is working overtime to cool the cab, the condenser gets hot, making it nearly impossible to effectively cool your transmission fluid. This results in significantly hotter running temperatures that can ruin your trip and drastically shorten the lifespan of your transmission. To combat this, Tier One offers two distinct high-performance solutions designed to bypass or upgrade that inefficient factory system.
Types of 2010-2012 Ram 6.7L Cummins Transmission Coolers
Depending on how you use your truck, you can choose between a fan-assisted auxiliary cooler or a high-capacity direct-fit cooler. Both options are vast improvements over stock and help solve the A/C condenser heat issue. Auxiliary Fan-Assisted Coolers (The Tier One Kit): The Tier One Auxiliary Transmission Cooler Kit is designed for extreme duty. It separates the transmission cooling from the A/C system entirely using a Derale 15870 40-Row Hyper-Cool Extreme Remote Cooler.- Active Cooling: Features a 10" waterproof/dustproof electric fan pushing 800 CFM, ensuring cooling even when idling or moving slowly.
- Performance: Rated at 67,000 BTUs per hour with a stacked plate design.
- Best For: Heavy towing at slow speeds, off-roading, and trucks running in high-heat environments.
- Massive Surface Area: Boasts a 60% increase in core volume and an 86% increase in external fin area compared to stock.
- Bypass Capability: Works with an available optional line kit to bypass the OEM cooler and integrated A/C condenser, eliminating the heat soak failure point.
- Durability: Features a robust tube and fin design perfect for rapid load changes and comes with the Mishimoto Lifetime Warranty.
