A multimode clutch assembly (128) is positioned in a powertrain of a rotorcraft. The multimode clutch assembly includes a freewheeling unit (130) having input and output races (136, 140). The freewheeling unit has a driving mode in which torque applied to the input race is transferred to the output race and an overrunning mode in which torque applied to the output race is not transferred to the input race. A bypass assembly (132) has an engaged position that couples the input and output races of the freewheeling unit. A hydraulic actuator (134) shifts the bypass assembly between the engaged position and a disengaged position. In the disengaged position, the overrunning mode of the freewheeling unit is enabled such that the multimode clutch assembly is configured for unidirectional torque transfer. In the engaged position, the overrunning mode of the freewheeling unit is disabled such that the multimode clutch assembly is configured for bidirectional torque transfer.
