ABSTRACT:
A control device for an automatic transmission of a vehicle delays or reserves a switching from one shift pattern to another for a predetermined time when a gear change occurs at the time of the shift pattern switching. When a shift pattern is to be switched from one to the other while the vehicle is running at a certain speed range in the one shift pattern, the switching is reserved temporarily and, after it is shifted to the gear shift stage in the one shift pattern, the shift pattern switching to the other is performed.
