It is not really a single part of Your car rather a group of drivetrain parts that interact with the engine to move the wheels and various parts of the vehicle to thrust it into motion which include the transmission, driveshaft, axles, differential, CV joints and the wheels.
If Your engine is shaking and there is reduced power or the vehicle is in limp mode, please DON’T drive and NEVER ignore a drivetrain malfunction warning. It is the transmission that changes the gearbox ratio to keep the engine speed relatively constant so without a drivetrain, the power your engine generates has no way of reaching the wheels and thus, your car won't move.
