ABSTRACT:
A method and a apparatus for operating an automatic synchronized transmission for motor vehicles. The transmission having a countershaft design, with a countershaft parallel to input and an output shafts, which communicate with each other and the countershaft by means of gear wheel pairs. The transmission further having at least one coupling and synchronization device for at least one idler gear, with the aid of which at least one idler gear can be rotationally fixed to a transmission shaft, such that when the motor vehicle is stationary and a starting gear is engaged, torque of the countershaft is not drive-effectively reduced. Thus, ensuring that when the starting gear is engaged, no undesired acceleration of the vehicle occurs.
