ABSTRACT:
An automated manual transmission has an input shaft having a plurality of driving gears, and an output shaft having a plurality of driven gears engaging with the driving gears, and further has two bypass clutches for coupling the input shaft and the output shaft with each other and releasing them from coupling. Electromagnetic valves are provided in hydraulic oil paths for guiding hydraulic pressure from a hydraulic pressure supply portion to the bypass clutches respectively. A bypass oil path for bypassing the hydraulic oil paths is provided with a bypass oil path on-off valve for opening the bypass oil path when the electromagnetic valves cannot be operated due to a failure of an electric system. A bypass oil path change-over valve is provided for changing over to supply hydraulic pressure from the bypass oil path on-off valve to one of the bypass clutches.
