  • Transit clutchless shifting of an auxiliary transmission
    Patent number: 5411450
    Abstract: A system for shifting gears in an auxiliary transmission is provided. The system enables shifting between gears of an auxiliary transmission without stopping the vehicle and without requiring a clutch between drive-line components. The system is activated by the operator while the vehicle is moving and includes safety features that preclude downshifting when the vehicle is traveling above a predetermined speed. The system is fully compatible with automatic main transmissions. An electronic control system monitors the rotational velocities or frequencies of the input and output shafts for clutchless shifting while the vehicle is moving.
