PURPOSE:To suitably set a line pressure supply hydraulic characteristic at the time of changing a speed and at the time of shifting to a reverse range by regulating a line pressure supply speed at the time of changing a speed and a line pressure supply speed at the time of shifting a reverse range with different orifices. CONSTITUTION:At the time of shifting from the second speed to the third speed, line pressure Pe is supplied through the first orifice 34 to a clutch 18. At the time of shifting to a reverse range, line pressure is supplied through the second orifice 50 to the clutch 18. Thus, the first and second orifices are suitably selected to set a suitable line pressure supply hydraulic characteristic to the clutch 18. |
