In modern usage, a torque converter is generally a type of fluid coupling that is used to transfer rotating power from a prime mover, such as an internal combustion engine or electric motor, to a rotating driven load. The torque converter normally takes the place of a mechanical clutch in a vehicle with an automatic transmission, allowing the load to be separated from the power source. It is usually located between the engine’s flexplate and the transmission.

Imagine you have two fans facing each other. Turn one fan on, and it will blow air over the blades of the second fan, causing it to spin, even though the two aren’t physically connected. But if you hold the second fan still, the first fan will keep right on spinning.

That’s exactly how a torque converter works. One “fan,” called the impeller, is connected to the engine. The other fan, the turbine, is connected to the transmission input shaft. Unless the transmission is in neutral or park, any motion of the turbine will move the vehicle.

At its core, a torque converter transmits torque from an engine’s crankshaft to the transmission input shaft using hydraulic fluid.
