Drive systems or powertrains including transmissions for electric and hybrid electric vehicles are provided. 3-position linear motor, 2-way clutches (i.e. CMDs) are included in the transmissions. An electric 3-speed AMT having a magnetic coupling device such as a magnetic torque converter is provided to magnetically transfer a portion of rotating mechanical energy of an electric powerplant or motor to a transmission output shaft in response to an electrical signal to synchronize angular velocities of the transmission output shaft and an output shaft of the electric powerplant during a change in state of one of the CMDs. Torque is transferred to the transmission output shaft during the change in state.
