PURPOSE: To transmit a propulsive torque even if the position of a selective lever is D, in the device of an automobile, by connecting a free wheel by applying a pressure to a brake parallel to the free wheel in shifting to the first gear in the position D of the selective lever. CONSTITUTION: When a selective lever 2 is operated, a hydraulic selection slider 3 of an automation transmission 1 is operated. On the other hand, this electric control device 4 confirms the position of the selective lever 2, and drives a solenoid valve 5 in accordance with the transmission stage, so that a pressure is applied to the clutch and the brake in accordance with the position of the hydraulic selection slider 3. In this case, when the selective lever 2 is charged over to the first gear in the position of D, a free wheel 12 belonging to the stage is connected by applying a pressure to a brake 10 parallel to the free wheel 12. |
