A transmission control system is proposed for reducing thermal load on engaging elements (2, 3, 4, 5) in a transmission (1) during the starting operation. The gearbox (1) has an input shaft (7) and an output shaft (9) and at least two engaging elements or clutches (2, 3, 4, 5) each of which is allocated to a gear and comprises a first clutch half (21, 31, 41, 51) which transmits the force coming from the direction of the input shaft (7) onto a second clutch half (22, 32, 42, 52) which in turn transmits the force in the direction of the output shaft (9). Transmission elements (11, 12, 13) and shafts (7, 8, 9, 23, 33, 40, 50) are mounted between the input shaft (7) and a first clutch (2, 3) and/or between the first clutch (2, 3) and a second clutch (4, 5) and/or between the second clutch (4, 5) and a further clutch or the output shaft (9). The engaging elements (2, 3, 4, 5) are actuated, via an actuation system (17) by a regulation and control unit (14) which receives system status data from sensors, in such a way that at least two of the engaging elements (2, 3, 4, 5) are actuated simultaneously during the starting operation.
