Abstract
A seven-speed transmission includes an input shaft, an output shaft, and three planetary gear sets. An interconnecting member continuously connects members of the second and third planetary gear sets. Six torque-transmitting mechanisms are provided between the planetary gear sets and a transmission housing. The six torque-transmitting mechanisms are engaged in combinations of two to establish seven forward speed ratios and a reverse speed ratio between the input shaft and the output shaft.
