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 including at least one rotary member; a rotary member enclosure enclosing the rotary member; and an oil reservoir arranged below the rotary member enclosure for collecting and reserving the oil. An oil separator is located facing the outer circumference of the rotary member for separating the oil adhering to the rotary member. Because the amount of oil left on the surface of the rotary member is reduced, the amount of oil recovered in the oil reservoir is accordingly increased and the level of the oil surface in the oil reservoir is prevented from falling.

摘要： A shift control system of an automatic transmission sets a predetermined gear stage by applying a first frictional engagement element and releasing a second frictional engagement element. A pressure regulating mechanism regulates an oil pressure to be fed to or drained from the first frictional engagement element. A failure detector detects a failure of an apparatus to participate in the regulation and control of the oil pressure which is to be fed to or drained from at least one of the first and second frictional engagement elements. A gear stage inhibitor inhibits the setting of the predetermined gear stage if the failure is detected by the failure detector.
