Abstract: PURPOSE:To prevent excessive rise in engine speed even at the time of a hold range operation by carrying out the shift up of the gear of an automatic transmission when a judging means judged above a defined speed in response to the output from an engine speed detecting means. CONSTITUTION:In an automatic transmission 1, when it is judged that an engine speed which is indicated by a speed signal N becomes above a defined value No by a speed judging part 18, the levels of a speed judging signal Ds and a travel judging signal Dc become H. Then, a gear position signal GP has been inputted into a shift up judging part 19 and a command signal D for shifting up to a gear position one stage above the gear position at that time is inputted into a gear change control device 10. Further, in response to the command signal D, the control device 10 carries out a gear shift up through a clutch control signal CS, an engine control signal ES, and a shift control signal SF which are outputted in accordance with the result of a control operation for making one-stage shift up of the gear position of a transmission 5, prior to other controls.
