PURPOSE:To prevent the time delay under selection, by providing an exchange valve to be controlled by a heat-sensitive member in an oil path for applying the oil pressure onto an friction element. CONSTITUTION:An exchange valve 102 having a spool 106 to be driven by a spring 110 made of heat-sensitive member is provided in an oil path 100 to be supplied with line pressure when a manual valve 2 is at the advance or retreat position. Consequently, the flow path area of the oil path 100 can be enlarged when the oil temperature is low, resulting in prevention of time delay under selection. |
