A power transmission system includes a multi-stage torque converter and an integrated vibration damper assembly. The torque converter fluid circuit includes, in series relation, an impeller, circulatory turbine, main turbine, and reaction member or stator. The vibration damper assembly includes an input member, an output hub assembly and a resilient member interposed between. The output hub assembly is operatively connected to the transmission output. A circulator turbine output is drivingly connected to an output shaft through the vibration damper assembly, rather than through the separate circulatory turbine drive plate of a conventional torque converter. In this matter, the vibration damper assembly where a conventional damper assembly would not provide a power output path.
