    • An automatic transmission has lower side and higher side friction engagement devices, with the lower side one being engaged and the higher side one being disengaged when a lower speed stage is engaged, while the lower side one is disengaged and the higher side one is engaged when the speed stage one higher than that lower speed stage is engaged. A control device for the transmission includes a shift valve for switching actuating fluid pressure between the lower side and the higher side friction engagement device and for draining the other one thereof, to provide the lower or the higher speed stage. An upshift smoothing valve is interposed in the drain path for the lower side friction engagement device for providing a higher flow resistance when a value representing engine output is relatively high and for providing a lower flow resistance when the value representing engine output is relatively low. Thus upshifting shock is reduced, particularly under low engine output conditions, in which overlapping of the engagement of the lower side and the higher side friction engagement devices is reduced. Optionally, the upshift smoothing valve may provide its higher or lower flow resistance, according as to whether the value representing engine output prevails over the actuating pressure for the higher stage friction engagement device, in a relationship between them, or not.

    • In an automatic transmission for a vehicle, a lock-up device is provided for a direct coupling clutch. The automatic transmission includes a fluid type torque converter having a hydraulic direct coupling clutch, and an auxiliary transmission having plural stages of gear trains. The lock-up control device has a valve for controlling the supply of oil pressure from a common oil pressure source to the direct coupling clutch, the valve having a body movable between opposite end positions and adapted to take a first switch position at one of the end positions when applied with a single signal pressure and a second switch position at the other end position, after release of the signal pressure, due to resilient force of a spring. The valve allows flow of the actuating oil pressure to the direct coupling clutch when the valve body is at both the first and second switch positions and interrupts the flow during shifting movement of the valve body from the first to second positions or vice versa. Thus, the direct coupling clutch is instantaneously disconnected during gear shifting operation over adjacent three gear ratios with use of the single signal pressure.

    • A direct-coupling control device for a torque converter for an automatic vehicular transmission in which a valve controlling the locking force of a direct-coupling mechanism is provided with two independently-formed pressure chambers pushing a valve body in a direction in which a locking force is increased. The device is also provided with a first fluid pressure output connected to one of the pressure chambers, and a second fluid pressure output connected to the other. When the first fluid pressure is higher than the second fluid pressure, the first fluid pressure acts on the sum of the individual working areas of the first and second fluid pressures on the valve body. A reliable speed change control can be provided by the two fluid pressures, and the capacity characteristics of the direct-coupling mechanism can be selected optimally with respect to these fluid pressures. The locking force of the direct-coupling mechanism can be increased quickly in proportion to increasing vehicle speed, and fuel costs can be reduced very effectively.
