A transmission system is provided utilizing multiple sets of clutch friction elements, each engaged to transfer torque from a torque input, such as an engine, to different gear ratios. The sets of clutch friction elements are operated simultaneously to provide a blended, gear ratio to a drivetrain. By varying the engagement of the clutch elements, and thus the proportion of the torque transferred to the gear ratio associated with each set of friction elements, an intermediate, effective gear ratio is developed. This effective gear ratio can be increased or decreased in response to external stimuli, such as vehicle and/or engine sensors, by modifying the degree of engagement of each set of clutch friction elements, and thus the proportion of torque transferred by each set of elements to its associated gear ratio.
