A powertrain includes an engine and torque converter, a planetary transmission, and a final drive mechanism. The planetary transmission is selected from a family of transmissions wherein each family member has a first, a second, and a third planetary gear set; and each planetary gear set has a first, a second, and a third member. All of the family members have five torque transmitting mechanisms of the rotating type commonly named clutches. Each of the first members of the first and second planetary gear sets is continuously connected with a stationary portion of the transmission, and each of the first members of the third planetary gear set and the second member of the second planetary gear set are interconnected for common rotation by a connecting member. The input shaft is continuously connected with a member of one of the planetary gear sets, and the output shaft is continuously connected with another member of the planetary gear sets. The five clutches provide selective interconnections between members of the planetary gear sets and also between the planetary gear members and the input and output shaft. The clutches are engaged in combinations of two to establish at least six forward speeds and a reverse speed.
