Abstract
An electronic means senses the difference in rotational speed between a main shaft gear to be engaged and the main shaft, and actuates a friction disc assembly to connect the low gear to the main shaft to accelerate the countershaft and thus the gear to be engaged if the gear speed is lower than the main shaft speed, and to connect the first gear to the transmission casing to decelerate the countershaft and thus the gear if the gear speed is higher than the main shaft speed, shifting from neutral into the desired gear ratio is prevented until the gear and main shaft speeds are synchronized.
