摘要： In an automatic transmission mounted on a front engine and front drive vehicle, a valve body is positioned not to be obstructed by a vehicle side subframe, and lower sections of the transaxle casing, transaxle housing and rear cover form an oil reservoir space. Also, the lower part of the front differential device is isolated from the oil reservoir space by an oil reservoir plate and a side weir formed on the transaxle housing, but oil flows partly between the isolated areas. By this structure, the oil reservoir space is formed extending generally over the lower part of the integrated casing, and, in particular, is formed from the large space below the transaxle casing and the housing.

摘要： A plurality of oil channels formed in a casing is communicated with a single rotating hydraulic actuator. The casing comprises a transaxle casing on which a valve body is disposed, and a rear cover is fixed to the transaxle casing. The oil channels extend outwardly from a boss section in the casing and are radially arranged in a single plane of the rear cover. Oil from the hydraulic actuator is instantly exhausted through oil holes of an inner drum, an annular indented groove of the boss section, indented portions of sector shape and the oil channels.

摘要： A thick-walled, narrow-width oil strainer positioned in a space formed between the contact surfaces of the transaxle casing and transaxle housing of an automatic transmission is disclosed. Both the upper body and lower bodies of the oil strainer are constructed with an angled cross section to provide a deep suction section and a deep discharge section. A filter element is supported by being interposed between the peripheral edge sections and supporting bosses of the two bodies, and is slanted at a prescribed angle with respect to the suction section and the discharge section. The strainer is mounted with the right and left openings of the discharge section interposedly supported by the pump body and the transaxle casing, so that the oil discharged from the valve body is sucked directly into the pump through the suction section, and the oil in the oil sump is sucked into the pump through the filter element.

摘要： An orifice is installed on an oil passage to a hydraulic servo for a direct clutch. In forward high speed running, a line pressure from the D range port of a manual valve is supplied to the hydraulic servo through an oil passage used for forward high speed running and a three way cock (non manual type). Then comparatively large amount of oil is supplied to the servo in accordance with the high speed running. In reverse running, the line pressure from the R range port of the manual valve is supplied to the servo through the orifice and the three way cock. Consequently, comparatively small amount of oil is supplied to the hydraulic servo.

摘要： A sequence valve for the first brake (B.sub.1) is installed, and the forward four speed modes are attained by two solenoid valves. At in the second speed mode of D range, hydraulic pressure is applied to the second brake hydraulic servo to restrain certain rotating element through the one-way clutch. After the application to the second brake hydraulic servo is completed, then the hydraulic pressure is applied to the sequence valve for the first brake, and through the sequence valve, the hydraulic pressure is applied to the first brake hydraulic servo. Accordingly, when up shifting from the first speed mode to the second speed mode, the shifting is conducted smoothly by the engagement of the second brake, after that the first brake is engaged. When up shifting from the third speed mode to the fourth speed mode, the first brake hydraulic servo is swiftly drained by the 3-4 shift valve. Consequently, the second clutch is engaged under the operation of the one-way clutch operated by the engagement of the second brake.
摘要翻译：安装第一制动器（B1）的顺序阀，通过两个电磁阀实现前进四速模式。在D档的二速模式下，液压被施加到第二制动液压伺服机构，以通过单向离合器来限制某些旋转元件。在第二制动液压伺服系统的应用完成之后，液压被施加到第一制动器的顺序阀，并且通过顺序阀将液压施加到第一制动液压伺服系统。因此，当从第一速度模式向第二速度模式上升时，通过第二制动器的接合，第一制动器接合之后，平滑地进行换档。当从第三速度模式向第四速度模式转换时，第三制动液压伺服系统通过3-4换档阀快速排出。因此，第二离合器在由第二制动器的接合操作的单向离合器的操作下接合。

摘要： The first and second emergency control valves are a back up device in case all solenoid valves are in failure (non electrified). When the first and second solenoid valves are all off due to wire disconnection and the like in case the manual valve is at the 3 range, a 1-2 shift valve is constrained by the first emergency control valve, so that the hydraulic control device becomes the third speed mode. In case t#e manual shift lever is at the 2 range and a 2-3 shift valve, the 2-3 shift valve are constrained by the first and the second emergency control valves, so that the hydraulic control device becomes the second speed mode. In case the manual shift lever is at the 1 range, the first emergency control valve is constrained, and the 2-3 shift valve is constrained by the second emergency control valve, so that the hydraulic control device becomes the first speed mode. When the manual valve is at the D range, the fourth speed mode is attained in case the first and second solenoid valves are all off.
