Patent ID: 7452302

Claim:
A multi-speed transmission comprising: an input shaft; an output shaft; first, second and third planetary gear sets each having first, second and third members; said output shaft being continuously interconnected with a member of said planetary gear sets; said input shaft being continuously interconnected with one of said members of said third planetary gear sets; a first interconnecting member continuously interconnecting said first member of said first planetary gear set with said first member of said second planetary gear set; a second interconnecting member continuously interconnecting said second member of said first planetary gear set with said second member of said second planetary gear set; a third interconnecting member continuously interconnecting said third member of said second planetary gear set with said first member of said third planetary gear set; a first torque-transmitting mechanism selectively interconnecting a member of said first planetary gear set with a member of said third planetary gear set; a second torque-transmitting mechanism selectively interconnecting a member of said third planetary gear set with another member of said first or second planetary gear sets; a third torque-transmitting mechanism selectively interconnecting a member of said first or second planetary gear sets with a stationary member; a fourth torque-transmitting mechanism selectively interconnecting a member of said second or third planetary gear set with said stationary member; a fifth torque-transmitting mechanism selectively interconnecting a member of said third planetary gear set with said stationary member; said torque-transmitting mechanisms being engaged in combinations to establish at least six forward speed ratios and at least one reverse speed ratio between said input shaft and said output shaft; and wherein said torque transmitting mechanisms establishing said speed ratios number not more than five.
