Abstract
An automatic transmission can automatically change gears as if it were manually operated when a gearshift lever is operated in a large-sized car. When a gear changing operation is found to be of a hooked type, a gear drawing or shifting control is carried out according to the position of the gearshift lever. Subsequently, without any recognition of the neutral position, a gear selecting control and then the next gear shifting control are performed.
