Transmission

A power transmission for use in a powertrain having an engine for providing rotary power to the transmission, said transmission comprising:

• an input shaft continuously connected with the engine for co-rotation therewith;
• a first planetary gearset having a first member driven by said input shaft, a second member, and a third member;
• a second planetary gearset having a first member driven by said second member of said first planetary gearset, a second member driving said output shaft, and a third member;
• a third planetary gearset having a first member driven by said second member of said second planetary gearset, a second member and a third member;
• a first torque transmitting mechanism that is operable to selectively engage said third member of said third planetary gearset for rotation with said input shaft;
• a second torque transmitting mechanism that is selectively operable to engage said first member of said first planetary gearset for rotation with said input shaft;
• a third torque transmitting mechanism for selectively braking rotation of said third member of said second planetary gearset;
• a fourth torque transmitting mechanism for selectively braking rotation of said third member of said third planetary gearset;
• a fifth torque transmitting mechanism for selectively braking rotation of said second member of said third planetary gearset, said fifth torque transmitting mechanism including an overrunning clutch that is operable in either of a released mode and a locked mode;
• and
• an actuator for shifting said overrunning clutch between its released and locked modes.
