Abstract
An apparatus for shifting a transmission coupled to an engine including a controller for shifting the transmission between operating modes, a control lever for switching the transmission, and an actuator for actuating the control lever in response to shifting of the controller. The apparatus includes a longitudinal tube connected to the controller, a cylindrical slide connected to the actuator for actuating the control lever in response to shifting of the controller, the longitudinal tube being coaxial with the cylindrical slide, a detector for detecting relative displacement between the longitudinal tube and the cylindrical slide, and a spring acting between the longitudinal tube and the cylindrical slide to prevent relative displacement between them until a force acting on one of them exceeds the spring force of the spring.
