ABSTRACT:
A method and apparatus for transmission shift control and prevention is provided. When the inching pedal is not depressed, the transmission is free to shift to the desired gear. When the inching pedal is depressed, the transmission is free to shift to the desired gear if the shift is a shift from a gear into neutral. With the inching pedal depressed and the shift lever moved from neutral into a gear, the transmission is free to shift if the transmission speed is below first gear high idle. When a directional shift has been requested, the transmission is free to shift to the desired gear if the transmission speed is below first gear high idle.
