Seven torque transmitting devices are each selectively engageable to interconnect one of the first, second, and third elements of one of the planetary gear sets directly with (i) one of the first, second, and third elements of another one of the planetary gear sets, (ii) a housing, or (iii) an input member. The seven torque transmitting devices are selectively engageable to establish nine forward speed ratios and at least one reverse speed ratio. Upon removal of a fourth torque transmitting device, the transmission is arranged in the 8-speed configuration and the remaining six torque transmitting devices are selectively engageable to establish eight forward speed ratios and at least one reverse speed ratio.
