Abstract:
A transmissions comprising:an input shaft adapted to deliver power to said transmission; an output shaft adapted to deliver power from said transmission; a stationary housing; a first planetary gearset having first, second, and third members; a second planetary gearset having first, second, and third members; a third planetary gearset having first, second, and third members; a first interconnecting member continuously interconnecting said first member of said first planetary gearset with said first member of said second planetary gearset; a second interconnecting member continuously interconnecting said second member of said second planetary gearset with said first member of said third planetary gear set; said third member of said second planetary gearset being continuously connected with said stationary housing, said input shaft being continuously connected with at least one member of one of said planetary gearsets, said output shaft being continuously connected with at least one member of one of said planetary gearsets not connected with said input shaft; and first, second, third, fourth, and fifth selectively operable torque transmitting mechanisms that selectively connect members of said planetary gearsets with other members of said planetary gearsets, said input shaft, said output shaft, or said transmission housing, said torque transmitting mechanisms being engaged in combinations of two to establish at least six forward speed ratios and a reverse speed ratio between said input shaft and said output shaft.
