PROBLEM TO BE SOLVED: To provide a partial communized solenoid valve and shift valve for shifting in a forward and reverse shift range. SOLUTION: In a shift controlling valve to control the supply oil pressure for proper engagement to a forward friction engagement element and a reverse friction engagement element, first linear solenoid valve 86 represented by linear A is provided between an oil passage 100 which is connected to a main regulator valve 50 as an original oil pressure supply source and a manual valve 58 which is connected to a low clutch 11 by means of the oil passage 121, 122, 156 and a reverse clutch 14 by means of the oil passage 130, 131, 132, 133. It is characterized in that the linear solenoid valve 86 can regulate the original oil pressure of the first oil passage 151, 152 or the second oil passage 155 arranged in parallel between the manual valve 58 and the oil passage 100 to a desired value. |
