An emergency operation for a power-operated vehicle transmission with a clutch driven by an operating cylinder (42) is proposed. For emergency operation of the transmission in the event of the control electronics (8) failing, pressure-medium control lines (29, 30) are provided, which are connected by way of spring-loaded non-return valves (44, 46) to a pressure-medium reservoir (1). At the same time the spring-loading of the non-return valves (44, 46) is adjusted so that these open only when the supply pressure of the pressure medium is in excess of the pressure necessary for operation of the clutch operating cylinder (42). <IMAGE> |
