Six speed planetary transmission mechanisms with three interconnected gearsets

A transmission comprising:

• an input shaft;
• an output shaft;
• a transmission housing;
• a first planetary gearset having a first member, a second member, and a third member;
• a second planetary gearset having a first member continuously interconnected by a first interconnecting member with said first member of said first planetary gearset, a second member, and a third member;
• a third planetary gearset having a first member continuously interconnected by a second interconnecting member with said second member of said second planetary gearset, a second member, and a third member;
• said input shaft being continuously interconnected with a member of a group consisting of said second member of said first planetary gearset, said third member of said second planetary gearset, said first interconnecting member, and said second interconnecting member;
• said output shaft being continuously interconnected with a member of a group consisting of said third member of said first planetary gearset, said third member of said second planetary gearset, and said second member of said third planetary gearset;
• and
• five selectively engageable torque transmitting mechanisms that selectively interconnect the members of the planetary gearsets with said transmission housing, said input shaft, said output shaft or other members of the planetary gearsets, and that are engaged in combinations of three to establish at least six forward speed ratios and one reverse ratio between said input shaft and said output shaft.
