An electric drive module for an electrified vehicle includes an electric motor, a transmission, a multispeed actuation mechanism (MAM), and a controller. The transmission is driven by a rotatable output of the electric motor and includes a first drive shaft and a second drive shaft. The transmission has a first gear set that selectively converts rotatable motion of the first drive shaft into rotatable motion of the second drive shaft in a first gear mode, and a second gear set that selectively converts rotatable motion of the first drive shaft into rotatable motion of the second drive shaft in a second gear mode. The MAM has magnetic fluid therein that activates causing selective rotatable communication between the first and second drive shafts. The controller commands activation of the MAM whereby a limited slip condition occurs between the first and second drive shafts thereby mitigating vibrations in the electric drive module.
