An automatic transmission of an automotive vehicle is set into a neutral position in response to a command instructing gear shifting of the automatic transmission when release of an accelerator pedal of the vehicle is detected. The automatic transmission has a plurality of speed clutches. The opening of a throttle valve arranged in an intake passage of an internal combustion engine installed on the vehicle is controlled such that the rotational speed of an input side of one of the speed clutches to be selected for the gear shifting and the rotational speed of the one of the speed clutches becomes substantially equal to each other when the automatic transmission is held in the neutral position. The one of the speed clutches is engaged upon detection that the rotational speed of the input side thereof and the rotational speed of the output side thereof becomes substantially equal to each other.
