Abstract
A control device for an automatic transmission, with a torque converter including a lock-up clutch, includes a learning unit configured to learn an engagement holding pressure, which is a hydraulic pressure immediately before the lock-up clutch is released, during coasting, and a determination unit configured to determine during learning in the learning unit whether or not an ON-failure in which the lock-up clutch is held in an engaged state in response to a release instruction has occurred.
