Abstract: A system and method for maintaining the operation of an automated transmission (16), particularly a dual dutch transmission, for a motor vehicle, in case of a failure of an engine speed sensor (50) or a bus connection (44) between a first control module (42) controlling an engine (28) being connectable to the transmission (16) through at least one separation clutch (12, 149), and a second control module (34) controlling regulating units (12, 14) for connecting the engine (28) to the transmission (16) or to one or more driving wheels (34) in a force-transmitting manner, wherein gear-shift relevant data, particularly a number of revolutions (no) of the engine, is exchanged between the control modules (34, 42) over the bus connection (44).
