The 8-speed automatic transmission in your 2019-2023 Ram 1500 3.0L EcoDiesel is a smooth operator, but it has its limits. When you start adding aggressive tuning, lift kits, massive tires, or tow heavy loads daily, the stock clutches and shafts can struggle to keep up with the EcoDiesel's low-end torque. Tier One offers high-performance, built 2019-2023 Ram 1500 3.0L EcoDiesel transmissions designed to handle the abuse that the stock unit can't. Whether you need a reliable replacement for a work truck or a built unit for a high-torque build, we have you covered. Our transmissions are engineered to fix common failure points and provide the holding power you need to drive with confidence. Even the best transmission build needs a reliable connection to the engine, so if you are piecing together your own build or need better towing response, look at our 2019-2023 Ram 1500 3.0L EcoDiesel Torque Converters. Protect your investment from heat while towing by adding one of our 2019-2023 Ram 1500 3.0L EcoDiesel Transmission Coolers. If you aren't ready for a complete transmission swap but want to fix shifting issues, a valve body replacement is a great place to start, so check out our 2019-2023 Ram 1500 3.0L EcoDiesel Valve Bodies. To get the most out of your new transmission, consider upgrading your fluid capacity or installing a thermal bypass valve from our section of 2019-2023 Ram 1500 3.0L EcoDiesel Transmission Parts.

About 2019-2023 Ram 1500 3.0L EcoDiesel Complete Transmissions

The transmission in your 2019-2023 Ram 1500 3.0L EcoDiesel is a workhorse, but every mechanical part has its limit. After years of heavy towing, high mileage, or aggressive driving, the stock transmission can start to slip, shudder, or fail completely. When that happens, you have a choice: go with a generic remanufactured unit that might have the same weak points, or upgrade to a built transmission from Tier One. We specialize in building 2019-2023 Ram 1500 3.0L EcoDiesel transmissions that are designed to handle real-world abuse, from heavy hauling to high-horsepower street builds.

Tier One's built transmissions feature upgrades where it counts. We use high-performance clutches with increased friction surface area, stronger steels, upgraded input shafts, and modified valve bodies to ensure reliable shifts and massive power-holding capability. We offer different "Stages" of transmission builds so you can match the transmission to your specific needsâ€”whether it's a reliable daily driver replacement or a fully billet competition unit. Don't settle for stock; get a transmission that's built to last from Tier One.
