The present invention provides a synchronous mesh-type automatic transmission control device for an automotive vehicle capable of stably shortening a transmission time, and simultaneously having a high durability.The control system comprises an input shaft 13 coupled with a crank shaft 1a of an internal combustion engine 1 through a clutch mechanism 2, an output shaft 16 coupled with the input shaft 13 through any one set of gears selected from the plural sets of transmission gears 17 to 21 each having a different gear ratio, a coupling mechanism 22 for coupling the input shaft 13 with the output shaft 16 by selecting one set of gears as above-mentioned, a shift and select actuator 5 for controlling a shift position and a select position of the coupling mechanism 22, and a control means 4, whereby a manipulating value of the shift and select actuator 5 is controlled by inputting its position signal, and moreover, a shift speed of the shift and select actuator 5 is controlled according to a rotating speed difference signal of the input shaft 13 and the output shaft 16 of the internal combustion engine 1.
