ABSTRACT:
A vehicle transmission control arrangement in which an automatic clutch is disengaged in response to a signal received from a shift lever switch provided to detect an operation of a shift lever for shifting a speed changing mechanism. A comparator is provided to determine whether a detected or determined output torque of an engine is smaller than a predetermined reference value below which an increase in the engine speed upon full disengagement of the clutch will not significantly deteriorate a driving comfort of the vehicle. A clutch control device is adapted to inhibit the clutch from being fully disengaged despite the presence of the signal from the shift lever switch, if the engine output torque is not smaller than the reference value.
