Abstract
A powertrain for a motor vehicle includes an engine disposed in a front of the motor vehicle and having an output member, an automatic transmission disposed in a rear of the motor vehicle and having an input member, a torque converter connected to the input member of the automatic transmission, and a shaft disposed along a length of the motor vehicle and connected to the torque converter. A first damper is connected to the output member of the engine and is connected to the shaft. The first damper has a first spring set interconnected to the output member of the engine and a second spring set interconnected to the first spring set and to the shaft. The first damper is operable to isolate torsional vibration between the engine and the shaft and isolate the shaft from torsional resonant behavior.
