[Object] It is an object of the present invention to provide a shift control unit to be adopted in an electric-power-assist-type transmission offering good operatability. [Solution Means] A shift disabling unit 86 employs a neutral-position detecting unit 81, a vehicle-speed judging unit 82, an engine-rotational-speed judging means 83, an OR circuit 84 and an AND circuit 85. The neutral-position detecting unit 81 is used for outputting an "H"-level signal to indicate that a gear is placed at a neutral position. The vehicle-speed judging unit 82 generates an "H"-level signal for a speed of a vehicle equal to or higher than 10 km/h. On the other hand, the engine-rotational-speed judging means 83 generates an "H"-level signal for a rotational speed of an engine equal to or higher than 3,000 rpm. The OR circuit 84 generates an "H"-level signal when the vehicle-speed judging unit 82 generates an "H"-level signal or the engine-rotational-speed judging means 83 generates an "H"-level signal. On the other hand, the AND circuit 85 generates an "H"-level signal when the neutral-position detecting unit 81 generates an "H"-level signal and the OR circuit 84 also generates an "H"-level signal. with the AND circuit 85 outputting the "H"-level signal, the shift disabling unit 86 prevents a shift change from being made.
