2023-2024 F250 & F350 6.7L Powerstroke Complete Transmissions

Your 6.7L F250 or F350 may be capable of making a ton of power and towing heavy, but its stock 10R140 transmission has a few critical design flaws—most notably the CDF drum bushing, which is prone to moving and blocking fluid flow, leading to catastrophic failure. Tier One's selection of built 10R140 transmissions are designed to address these internal weaknesses while handling the strain of big-time power modifications. Each of these built 10R140 transmissions feature updated OEM components, an updated CDF drum design, and aftermarket performance upgrades that all work together to improve power-holding, towing capability, and long-term reliability all in one transmission. These built 10R140 transmissions drop right into place of your stock transmission without the need for programming or other modifications. Even the best transmission build needs a reliable connection to the engine, so if you are piecing together your own build or need a specific stall speed, look at our 2023-2024 F250 & F350 6.7L Torque Converters.
