  • Patent number: 8292771
    Abstract: A hydraulic control apparatus of an automatic transmission including a switching portion which, at the same time as a reverse range pressure oil passage and a discharge delay oil passage which delays an oil pressure output are connected, causes the reverse range pressure oil passage and discharge delay oil passage, by switching between the two, in order to communicate with a hydraulic servo. The switching portion causes the hydraulic servo and discharge delay oil passage to communicate when a manual valve is switched to an N range, and causes the hydraulic servo and reverse range pressure oil passage to communicate when the manual valve (MV) is switched to a D range or an R range. Because of this arrangement, it is difficult for oil, when discharged from the hydraulic servo, to drain at an R-N switching time, and it is easy for oil to drain in the D range or the like.
