This is a very basic question. I understand that the torque is passed from the engine onto the transmission via the flywheel in manual transmission or flexplate in case of automatic. The transmission converts the input torque to an gear who size corresponds to the current vehicle movement. What I do not understand is how the processed torque output of the transmission gets passed onto the differential, which I understand is the ultimate conveyor of power to the wheels.
Please correct any possibly incorrect assumptions above.
