PURPOSE: A transmission is provided to increase efficiency and responsibility by including a plurality of planet gear sets and torque delivery devices. CONSTITUTION: A transmission includes an input member (12) and an output member (22). The input member is consecutively combined with a first node (14A) of a first planet gear set (14). The output member is consecutively combined with a first node (20A) of a fourth planet gear set (20). Seven torque delivery tools establish a plurality of advance speed ratios. The torque delivery tools establish one or more backward speed ratios. |
