What component transfers torque to the transmission flywheel?

The crankshaft is the correct component that transfers torque to the transmission flywheel. In an internal combustion engine, the crankshaft converts the linear motion of the pistons into rotational motion, which is essential for the operation of the vehicle. As the crankshaft rotates, it generates torque that is transmitted to the flywheel, an important part of the transmission system. The flywheel plays a crucial role in smoothing out the power delivery from the engine to the transmission, and it also helps with starting the engine and maintaining its momentum.

Other components listed do not play a direct role in transferring torque to the transmission flywheel. The transmission filter is responsible for filtering the transmission fluid, while the drive shaft transmits power from the transmission to the wheels. The camshaft controls the opening and closing of the engine valves, which is separate from the torque transfer process. Therefore, the crankshaft plays a central role in the function of the engine and its connection to the transmission system.
