ABSTRACT:
In a control apparatus for a vehicular automatic transmission having transmission trains of five forward speeds or more, the transmission trains are divided into two groups of a low-speed system made up of relatively low-speed transmission trains and a high-speed system made up of relatively high-speed transmission trains. A main shift valve is provided for selectively supplying pressurized oil supplied from a manual valve through a first oil supply passage to an oil passage for the low-speed system and to an oil passage for the high-speed system. A shift valve unit for the low-speed system, which unit has one or more shift valves for selectively establishing transmission trains belonging to the low-speed system, is interposed in the oil passage for the low-speed system. A shift valve unit for the high-speed system, which unit has one or more shift valves for selectively establishing transmission trains belonging to the high-speed system, is interposed in the oil passage for the high-speed system.
