Abstract:
A transmission mechanism having at least six forward speeds comprising:an input shaft; an output shaft; a transmission housing; first, second, and third planetary gearsets each including first, second, and third members, said first member of said first planetary gearset being continuously interconnected with said first member of said second planetary gearset through a first interconnecting member, said second member of said first planetary gearset being continuously interconnected with said first member of said third planetary gearset through a second interconnecting member, said second member of said second planetary gearset being continuously interconnected with said second member of said third planetary gearset through a third interconnecting member, said third member of said first planetary gearset being continuously interconnected with said transmission housing, said output shaft being continuously interconnected with at least one member of one of said planetary gearsets; and five torque transmitting mechanisms, said torque transmitting mechanisms being selectively engaged in combinations of two to establish at least six forward speed ratios and one reverse speed ratio in said transmission mechanism.
