Multi-speed power transmission with three planetary gear sets

A family of transmissions comprising:

• an input shaft;
• an output shaft
• a planetary gear arrangement comprising first, second, and third planetary gear sets, each planetary gear set including first, second and third members;
• five selectively operable torque transmitting mechanisms;
• first and second interconnecting members;
• said first interconnecting member continuously interconnecting said first member of said first planetary gear set with said first member of said second planetary gear set, said second interconnecting member continuously interconnecting said second member of said first planetary gear set with said second member of said second planetary gear set, said first member of said third planetary gear set being continuously connected with a stationary portion of said transmission;
• said input shaft being continuously connected with one of said first interconnecting member, said second interconnecting member, said third member of said first planetary gear set, said third member of said second planetary gear set, and said second member of said third planetary gear set;
• said output shaft being continuously connected with one of said first interconnecting member, and said third member of said second planetary gear set;
• a first of said torque transmitting mechanisms selectively connecting one of said first and second interconnecting members with one of said input shaft, said second member of said third planetary gear set, and said third member of said second planetary gear set;
• a second of said torque transmitting mechanisms selectively connecting one of said first and second interconnecting members with one of said second and third member of said third planetary gear set;
• a third of said torque transmitting mechanisms selectively connecting one of said second interconnecting member, said third member of said third planetary gear set, and said third member of said first planetary gear set with one of said first interconnecting member, said second member of said third planetary gear set, said third member of said third planetary gear set, said input shaft, and said output shaft;
• a fourth of said torque transmitting mechanisms selectively connecting one of said input shaft and said third member of said first planetary gear set with one of said second member of said third planetary gear set, said third member of said third planetary gear set, said first member of said third planetary gear set and said third member of said first planetary gear set;
• a fifth of said torque transmitting mechanism selectively connecting one of said stationary portion and said second member of said third planetary gear set with one of said second interconnecting member, said third member of said second planetary gear set, said input shaft, and said output shaft;
• and
• said five torque transmitting mechanisms being selectively engaged in combinations of two to establish at least six forward speed ratios and one reverse ratio in said planetary gear sets between said input shaft and said output shaft.
