ABSTRACT:
A powertrain includes a power transmission having an input shaft continuously connected directly between an engine and a planetary gear member of a first planetary gearset. Another member of the planetary gearset is selectively grounded by a torque transmitting mechanism to establish a reaction member during the launch of a vehicle incorporating the powertrain. The reaction member is established during both the lowest forward drive ratio and the reverse drive ratio. A third member of the planetary gearset transmits the torque from the input shaft, as modified by the planetary gearset, to other planetary gearsets in down stream power flow arrangement with the first planetary gearset.
