To quickly accelerate a car body after switching of a speed change shift, in a speed change control device for a mechanical automatic transmission.

This speed change control device for a mechanical automatic transmission, having a friction clutch and a speed change mechanism to perform speed change operation by respectively controlling a connection condition of this friction clutch and a speed change condition of this speed change mechanism, comprises an input shaft rotational speed detection means 10 detecting a rotational speed of an input,shaft of this speed change mechanism, a target speed change shift setting means 1A setting a target speed change shift of this speed change mechanism, and a target engine speed setting means 2A setting a target speed of an engine, the target engine speed setting means 2A sets this target engine speed, just after switching from the present speed change shift to this target speed change shift, higher than this input shaft rotational speed in this target speed change shift.
