    摘要： In order to control the engine output timing always properly irrespective of the aging of an automatic transmission, the present invention provides a shift control system for a vehicular automatic transmission, which system comprises: release end detecting means for detecting the release end of a frictional engagement element for a higher gear stage, at a shifting time from higher to lower gear stages; synchronism detecting means for detecting the synchronism between an engine R.P.M. and a rotating element in the automatic transmission at the lower gear stage; and engine output control means for controlling the output of the engine. The aforementioned engine output control means starts the rise control of the engine output, when the release end of the frictional engagement element for the higher gear stage is detected by the release end detecting means, and ends the rise control of the aforementioned engine output when the synchronism between the engine R.P.M. and the rotating element in the automatic transmission at the lower gear stage is detected by the synchronism detecting means.

    摘要： In an automatic transmission according to the present invention, a coast brake cutoff valve is arranged between a range-pressure-producing manual valve and shift valves and, when changed over, selectively feeds oil to hydraulic engine brake servomotors. An engine brake solenoid valve is on/off controlled by a shifting output signal from a CPU, whereby the coast brake cutoff valve is selectively changed over. A lockout valve is arranged between the coast brake cutoff valve and the manual valve and is connected to one of shifting solenoid valves. The automatic transmission can therefore be operated without trouble even when an electrical problem occurs in the shifting solenoid valves and/or the engine brake solenoid valve.

    摘要： An automatic transmission includes a first rotating element provided by a sun gear of a second planetary gear set, a second rotating element provided by coupling carriers of the second planetary gear set and a third planetary gear set to each other, a third rotating element provided by coupling ring gears of the second and third planetary gear sets to each other, and a fourth rotating element provided by a sun gear of the third planetary gear set. The second and third planetary gear sets are combined with a first planetary gear set so that the automatic transmission can provide seven forward gear stages by changing a combination of two engaging elements, such as clutches and brakes, for coupling or stopping the corresponding rotating elements.
