Abstract
A transmission includes an input shaft, an output shaft, at least five planetary gearsets, a variable-ratio unit, and at least six clutches. The input shaft is configured to receive torque from a drive unit. The output shaft is configured to transmit torque to a load. The at least five planetary gearsets, the variable-ratio unit, and the at least six clutches are arranged between the input shaft and the output shaft. The at least six clutches are selectively engageable in combination with one another to select one of at least eight operating modes.
