How Transmission Torque Converters Work

In general terms, a torque converter is a type of fluid coupling (torque multiplier) that is used to transfer rotation power from a prime mover, such as an combustion engine or electrical motor, to a rotating driven load.

If you have some knowledge of manual transmissions, you are aware that an engine is connected to a transmission by way of a clutch. Without a clutch, a car would not be able to come to a dead stop without killing the engine. The challenge with automatic transmission engines is that their transmissions have no clutch that disconnects the transmission from the engine. Rather, they use a device called a converter. It may not look like much, but there is a lot going on inside.
