A shift-by-wire system comprises an integrated park module including a slider, a motor, a spring, and an actuator system. The slider can be disposed in a park position (PP) and a not-parked position (NPP) corresponding to a park mode and a not-park mode of a transmission, respectively. The motor and a gear-train cause the slider to move from the PP to the NPP and the spring urges the slider from the NPP to the PP. The actuator system retains the slider in the NPP after the motor and the gear-train have disengaged from the slider. The gear-train includes a default position (DP) corresponding to the PP and a maximum lift region (MLR) in which the actuator system retains the slider in the NPP. The gear-train rotates from the MLR to the DP while the actuator system retains the slider in the NPP.
