A belt driven automatic transmission for producing a continuous range of drive ratios includes an input pully rotatably mounted on the axis of an engine crankshaft and an output pulley rotatably supported on the axis of the transmission output shaft. The pulleys are driveably connected by an endless drive belt, whose radial position on the pulleys varies in accordance with the position of axially displaceable sheaves that move in accordance with the magnitudes of pressure in actuating cylinders. The pulley system is driveably connected to the impeller of a hydrokinetic torque converter whose turbine is driven from the impeller. The turbine is continously connected to the output shaft. A forward and reverse planetary gearset is driven from the transmission selectively in accordance with the position of synchronizer sleeve. The carrier of the gearset is integrally formed with a driving sprocket engaged by an endless drive chain that is driveably connected to an output sprocket rotatably supported on the axis of a differential mechanism. Right-hand and left-hand axle shafts that support the drive wheels of the vehicle are driven differentially by the differential mechanism through a constant velocity joint.
