Transmission control device and transmission control method
In a transmission control device for controlling a transmission, a controller determines failure of a specific section. The controller variably controls line command pressure and secondary command pressure, and in a case where the failure is determined, fixes the line command pressure to a line pressure set value and the secondary command pressure to a secondary pressure set value. In a case where the failure is determined, the controller further starts a change in the secondary command pressure after start of a change in the line command pressure, and controls the secondary command pressure in such a manner that the secondary command pressure takes a first predetermined time to have the secondary pressure set value.
