PURPOSE:To satisfy both demands of prevention of transmission shock and transmission response at a high level by providing a passing prohibiting means for carrying out transmission without passing other hydraulic pressure operating states when change rate of engine load detected by a transmission rate detecting means is more than a predetermined value. CONSTITUTION:At P1, it is judged whether a throttle opening degree is more than a predetermined value or not. When the judgment at this P1 is Yes, it is judged whether stepping-in speed of an accel is more than a predetermined value or not. The stopping-in speed of the accel is calculated by differentiating an accelerator opening degree. When the judgment at this P2 is No, a first to a third solenoids 76 to 78 are all turned off to obtain the state of an intermediate position. After that, at P4, it is judged whether a predetermined time (D, several seconds) has passed or not after the intermediate position is obtained. Moreover, when the judgment at P1 is No, or when the judgment at P2 is Yes, the program goes to P5 without passing P3 and P4. |
