1. A shifting actuator for a transmission, comprising:
a rotatable screw shaft;
a screw nut configured to threadedly engage the screw shaft and linearly move along the rotatable screw shaft;
a guide configured to guide the screw nut;
a control finger integrally formed with the screw nut; and
a first slider and a second slider disposed parallel to each other, wherein the first and second sliders are adapted to be selected by the control finger so as to linearly slide in an axial direction parallel to a longitudinal direction of the rotatable screw shaft,
wherein the screw nut is provided with a guide hole in which the guide is disposed, and the guide hole defines two linear zones spaced apart from each other and parallel to each other.
