The Ford TorqShift is a family of heavy-duty automatic transmissions engineered by Ford Motor Company for its Super Duty truck and commercial vehicle lineup. It was introduced for the 2003 model year to replace the aging 4R100 transmission, which had been paired with the 7.3L Powerstroke and other large-displacement engines in Ford's heavier trucks. The lineup has evolved across three primary generations, encompassing 5-speed, 6-speed, and 10-speed variants designed to manage high-torque commercial and heavy-towing applications.
The TorqShift family was engineered from the ground up to handle high output torque demands from modern turbo-diesel and high-displacement gasoline V8 and V10 engines. Unlike standard-duty passenger car and light truck units, all TorqShift iterations incorporate high-capacity planetary gearsets, heavy-duty fluid cooling systems, and specialized electronics designed to sustain continuous commercial hauling.
A key feature introduced with the platform was an integrated "Tow/Haul" mode. When enabled by the driver, the transmission control module alters shift logic to delay upshifts during acceleration, preventing gear hunting under load. It also enables automatic downshifting during deceleration to leverage engine braking on downward inclines, reducing wear on the service brakes.
The first transmission to carry the TorqShift name was the 5R110W, introduced for the 2003 model year to handle the increased torque of the 6.0L Power Stroke diesel engine. It featured a unique planetary gear arrangement containing six forward gear ratios, though it was electronically controlled as a 5-speed under standard operating temperatures. In extreme low-temperature scenarios (below −5 °F / −21 °C), the control module alters the shift sequence to utilize the 1.09:1 fourth ratio instead of direct drive (1.00:1) to allow faster fluid warm-up.

The second-generation TorqShift, designated the 6R140, was introduced for the 2011 model year. Built using a heavy-duty Ravigneaux gear train, it was designed to accommodate the significantly higher torque ratings of the in-house 6.7L Power Stroke V8 diesel and the 6.2L Boss V8 gasoline engines. It added a sixth gear for improved fuel efficiency during highway cruising and featured an optional Live-Drive Power Take-Off (PTO) output-shaft provision, allowing auxiliary equipment to run while the truck was stationary or moving.

- 2016-2019 Ford F-650 and F-750 medium-duty trucks
- 2017-present Ford E-Series chassis cabs and cutaways
The third-generation TorqShift, designated the 10R140, debuted for the 2020 model year. It expanded the architecture to a wide-ratio 10-speed layout featuring four overdrive gear ratios. Designed to keep engines operating within their optimal powerbands under extreme loads, the unit utilizes real-time adaptive shift controls and a lightweight aluminum case without compromising structural rigidity.
