An automatic transmission control device controls multiple speed changes in which shifting from first speed to second speed occurs during shifting from second speed to first speed. The control device includes a shift lever position sensor (200), an ECT_ECU (100), and an AT linear solenoid (600). The ECT_ECU (100) includes a circuit that detects multiple speed changes; a circuit that controls the AT linear solenoid (600) such that an engagement pressure of an engaged first speed engine brake friction element (B- 4) sweeps down when multiple speed changes are detected; and a circuit that commands a shift to second speed once a predetermined time has passed since the detection of multiple speed changes assuming that the engagement pressure of the first speed engine brake friction element (B - 4) has sufficiently swept down.
