controlled throttle shifting function provides smoother shifting for all shifts that do not fall under the control of the abusive shift logic.On upshifts, the controlled throttle shifting function is accomplished by briefly lowering the throttle for the duration of the shift. This lowering of the engine speed allows the engine speed to more closely match the transmission input speed at the end of the shift.On downshifts, the controlled throttle shifting function is accomplished by briefly raising the throttle for the duration of the shift. This raising of engine speed allows the engine speed to more closely match the transmission input speed at the end of the shift.When the brakes are applied, the normal controlled throttle shifting commands are cancelled. When the normal controlled throttle shifting commands are not cancelled, the stopping distance is greater. This would occur due to the increase in engine speed as the machine does each downshift.
