A family of power transmissions which are utilized in a powertrain include three planetary gearsets and five torque-transmitting mechanisms. The torque-transmitting mechanisms are engaged in combinations of two to provide a reverse drive ratio and six forward speed ratios. The torque-transmitting mechanisms include at least three rotating type torque-transmitting mechanisms and, two stationary type torque transmitting mechanisms in some family members, four rotary type torque transmitting mechanisms and one stationary type torque-transmitting mechanism in other family members, and five rotary type torque transmitting mechanisms in still other family members. The planetary gearsets are of either the single pinion type or of the double pinion type of planetary gearsets.
