Which component is responsible for transferring engine power to the transmission?

The component that is responsible for transferring engine power to the transmission is the torque converter. This hydraulic device is located between the engine flywheel and the transmission bell housing. Its primary function is to allow the engine to keep running while the vehicle is stationary and to smoothly transmit power to the transmission without physical connection, which can lead to engine stall or harsh shifting.

When the engine is running, the torque converter utilizes fluid dynamics to transfer power from the engine to the transmission. It consists of an impeller (connected to the engine), a turbine (connected to the transmission), and a stator (which helps improve efficiency). As the engine's flywheel spins, it rotates the impeller, pumping transmission fluid which, in turn, causes the turbine to spin and transfer the engine power to the transmission effectively.

In contrast, the planetary gear set is responsible for varying gear ratios within the transmission but does not directly transfer power from the engine. The hydraulic system plays a role in operating the transmission's functions, such as shifting gears, but again, it does not directly transfer engine power. Clutch packs serve to engage and disengage power transfer in manual and automatic transmissions but are not the primary component for transferring power from the engine to the transmission. Therefore, the
