Abstract
A transmission constructed according to the present invention includes a plurality of planetary gear sets, two inputs clutches being simultaneously engaged to establish an intermediate gear ratio within the transmission, each of the input clutches also being engaged together with additional friction devices in the transmission for establishing gear ratios either higher or lower than the intermediate gear ratio, the interconnection of the planetary gear units being selected for improved torque transmission, the input clutches being interrelated by means of a balancing mechanism to facilitate their operation either in unison or separately from each other.
