Abstract
A control device for a transmission including m (m≧3) solenoid valves and configured to establish a plurality of shift speeds by engaging n1 (2≦n1<m) engagement elements using hydraulic pressures of n1 solenoid valves among the m solenoid valves, the control device. The control device having an actual current value detection unit that detects respective values of actual currents flowing through solenoids of the m solenoid valves; and a determination unit that determines whether or not braking torque is generated on an output shaft of the transmission by comparing the detected actual current values for solenoids of n2 (n1<n2≦m) solenoid valves and a current threshold.
