PURPOSE:To make ensurance of engaging response compatible with reduction of the occurrence of a shock by operating a timing valve for a second set time shorter than a first set time during a shift, wherein the engaging state of other frictional engaging element is simultaneously shifted, when a specified frictional engaging element is engaged. CONSTITUTION:A bypass circuit 143 to feed an oil pressure to a specified frictional engaging element, such as a 2-4 brake 45, in a way to bypass an orifice 74 for an accumulator and a timing valve 103 to control an oil pressure feed timing are provided. Further, a control means 47 operates the timing valve 103 for a first set time during a shift wherein the 2-4 brake 45 is engaged and operates the timing valve 103 for a second set time shorter than the first set time during a shift wherein the engaging state of other frictional engaging element, such as a low reverse brake 46, is simultaneously shifted is provided. This constitution makes ensurance of engaging response during a shift, wherein the 2-4 brake 45 is operated, compatible with reduction of the occurrence of a shock during a shift wherein the low reverse brake 46 is worked. |
