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.
A unique engagement sequence is provided for the torque-transmitting mechanisms
to minimize sun gear loading.
