ABSTRACT:
A powertrain has a planetary gear arrangement with a simple planetary gear set and a compound planetary gear set which are interconnected by a continuous drive connection and are controlled to provide five forward drive ratios, a reverse drive ratio and a neutral condition. A plurality of torque transmitting devices including four clutches and two brakes are engaged in combination of three for each drive ratio. Two of the torque transmitting devices are engaged during the lowest forward drive ratio, the reverse drive ratio and the neutral condition.
