ABSTRACT:
An electro-mechanical controller for a transmission selector in a synchronized countershaft transmission, includes a selector shaft which is driven linearly and rotatably by a power actuator mechanism to provide gear selection within the countershaft transmission. A selector rod is coupled with the selector shaft through a connection that provides compliance and damping therebetween. The selector rod has a finger mechanism which is selectively connectible with synchronizers in the transmission to provide the desired gear selection. The selector shaft and selector rod are controlled in both linear and rotatable motion by translating mechanisms in the actuator mechanism to thereby control the selector rod in the gear selection positions and in a neutral condition.
