Abstract:
1. A multi-speed transmission comprising: an input member; an output member; a first planetary gear set having: a second and a third planetary gear set each having first, second and third members, and having at least one continuous interconnection therebetween, said second sun gear member being continuously interconnected with a first member of said second planetary gear set; wherein said output member is continuously interconnected with a first member of said third planetary gear set; wherein said input member is continuously interconnected with said first sun gear member; a first torque-transmitting mechanism selectively engageable to connect said input member with said carrier member; a second torque-transmitting mechanism selectively engageable to connect said carrier member with a stationary member; wherein said first torque-transmitting mechanism is engaged to establish a first predetermined speed ratio between said second sun gear member and said input member in a first direction of rotation; and wherein said second torque-transmitting mechanism is engaged to establish said first predetermined speed ratio between said second sun gear member and said input member in a second direction of rotation opposite said first direction of rotation.
