Patent ID: 8011261

Claim:
A transmission comprising: an input member; a torque converter continuously connected with the input member; an output member; a first, second, third, fourth, fifth, sixth, seventh, eighth, and ninth gear set each having a first gear and a second gear, wherein the output member is continuously connected with one of the gear sets; a first interconnecting member continuously connected to the eighth and ninth gear sets; a second interconnecting member continuously connected with the third and fourth gear sets; a countershaft continuously connected to the first, second, fifth, sixth, and seventh gear sets; a dual clutch assembly selectively engageable to interconnect the input member with one of the first interconnecting member and the second interconnecting member; and four synchronizer assemblies for selectively coupling one of the first, second, third, fourth, sixth, seventh, eighth, and ninth gear sets with one of the first interconnecting member, second interconnecting member, and the countershaft, and wherein the dual clutch assembly and four synchronizer assemblies are selectively engageable in combinations of at least two to establish at least seven forward speed ratios and at least one reverse speed ratio between the input member and the output member.
