An engine mount, made of rubber and steel, has two purposes. One, it secures the engine and transmission to the frame of the car, and two, it absorbs the road shocks and engine vibrations so that the driver does not feel any engine movement. Transmission mounts secure the transmission. Most cars have multiple engine and transmission mounts. If one of the mounts breaks, you will feel significant engine movement (vibrations and/or shaking).
