摘要：
For an automatic transmission for a vehicle such as an automobile having a friction engaging mechanism such as a brake which is engaged at two jumping apart speed stages such as the fourth speed stage under the D range and the second speed stage under the S range, a hydraulic control device switches over such a friction engaging means by a single shift valve with a drain port thereof for the friction engaging means being selectively supplied with a hydraulic pressure.
