A belt-driven transmission having an endless torque-transmitting member that is operatively connected with two power transmitting elements. The transmission includes at least one guide rail assembly that engages the endless torque-transmitting member with free play and that has an outer guide rail and an inner guide rail so that the endless torque-transmitting member runs within a guide rail channel defined by the outer and inner guide rails of the guide rail assembly. The endless torque-transmitting member includes one surface that is at least partially provided with outwardly-extending tabs and another, tab-free surface. The guide rail assembly is pressed against the endless torque-transmitting member on the tab-free surface to limit vibratory amplitude of the endless torque-transmitting member during operation of the transmission.
