Patent ID: 7291087

Claim:
A power transmission comprising: a first planetary gearset having a first member, a second member, and a third member; a second planetary gearset having a first member, a second member, and a third member; an input shaft; an output shaft; a first synchronizer mechanism for selectively interconnecting said first member of both of said planetary gearsets with said input shaft and for interconnecting said input shaft with said second member of said second planetary gearset; a second synchronizer mechanism for selectively interconnecting said second member of said first planetary gearset with said input shaft and for selectively interconnecting said second member of said first planetary gearset with a stationary member of said transmission; a third synchronizer mechanism for selectively interconnecting said third member of said first planetary gearset with said second member of said second planetary gearset, and for selectively interconnecting said third member of said first planetary gearset with said stationary member; and means for interconnecting said third member of said second planetary gearset with said output shaft wherein said synchronizer mechanisms are selectively engageable to provide at least six forward speed ratios and a reverse speed ratio between said input shaft and said output shaft.
