The torque converter works by utilizing transmission fluid to transfer the power from the engine to the transmission. It consists of a pump , a reactor , and a turbine. The pump and turbine look very similar as they both feature metal fins fanned all around their circumference. The main difference between these two components is the orientation of the fins and the components they are attached to. The pump is driven by the engine, while the turbine drives the transmission.
