摘要： An automatic transmission control system is equipped with a pressure modulating valve for regulating the engaging pressure to be supplied to frictional engagement elements for setting respective gear stages of the automatic transmission, a signal pressure output valve for providing signal pressure, and a switching valve. The control system further includes a switching valve for switching destinations of signal pressure for setting pressure regulation level between pressure modulating valve and other control valve; an abnormality-detection element for detecting, in gear shift to a gear stage set by the frictional engagement elements engaged on delivery of regulated oil pressure, abnormal regulation of engaging pressure to be delivered to the frictional engagement elements and abnormal operation due to delivery of the signal pressure to the control valve; and gear-shift-inhibition element for inhibiting shift to the gear stage in case that the abnormality-detection element detects at least one of abnormal pressure regulation and the abnormal operation.

摘要： An oil seal member is compressed between a connecting pipe for supplying oil to an oil chamber of a hydraulic servo and the cylinder drum of the hydraulic servo. The cylinder drum has an interior oil chamber and turns through a predetermined angle upon operation of a frictional engagement element by the hydraulic servo. The end of the seal member pressed against the cylindrical drum surrounds an oil hole 73 formed in the cylindrical drum, and oil pressure is supplied to the oil chamber through an oil passage in which the seal member is mounted and through the oil hole. A recess is formed in the outer surface of the cylindrical drum around the oil hole and the end of the seal member is received in the recess. When the cylindrical member turns within the predetermined angular range, the end of the seal member is protected by the recess. As a result, the end of the seal member is not damaged and the integrity of the seal is protected.

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.
