Abstract
A power transmission incorporates an input planetary gearset and an output planetary gearset, which are interconnected by a plurality of torque-transmitting mechanisms to establish at least seven forward speed ratios. The input planetary gearset has one member selectively connected with the input shaft and another member continuously connected with a stationary member. The output planetary gearset has one member continuously connected with the output shaft and a plurality of the members interconnected either with a stationary member through the torque-transmitting mechanisms or with the third member of the input planetary gearset to the torque-transmitting mechanisms, or with the input shaft through a torque-transmitting mechanism.
