A family of power transmissions wherein each family member includes first, second, and third planetary gearsets, six torque-transmitting mechanisms, and one continuous interconnecting member. The interconnecting member interconnects a member of the first planetary gearset, a member of the second planetary gearset, and a member of the third planetary gearset. The torque-transmitting mechanisms being selectively engageable in combinations of four to establish at least seven forward speed ratios and one reverse speed ratio within the planetary gearset.
