摘要： To prevent the neutral state from being formed in a change gear apparatus and allow the obtaining of an intended gear change appropriately during a servo malfunction. Hydraulic servos engage and disengage a plurality of friction engagement elements; a hydraulic pressure supply system supplies the hydraulic servo of a predetermined friction engagement element with hydraulic pressure; and an auxiliary hydraulic pressure supply systems supplies a predetermined hydraulic servo with another hydraulic pressure, in the case where the hydraulic pressure supply system is placed in a first unsupplied state where the hydraulic pressure supply system cannot supply the hydraulic servo of the predetermined friction engagement element with hydraulic pressure. The auxiliary hydraulic pressure supply system does not supply the predetermined hydraulic servo with the other hydraulic pressure, in the case that the hydraulic pressure supply system is placed in a second unsupplied state where the hydraulic pressure supply system does not supply the hydraulic servo of the predetermined friction engagement element with hydraulic pressure.

摘要： A shift control apparatus of an automatic transmission of a motor vehicle to which torque is transmitted from an engine via a fluid coupling device is provided. In the automatic transmission including a plurality of hydraulically operated friction elements, a clutch-to-clutch downshift is carried out during coasting of the vehicle by releasing one of the friction elements and engaging another friction element. A controller of the shift control apparatus detects a difference between input and output rotation speeds of the fluid coupling device, and increases an engine speed by a controlled amount based on the difference between the input and output rotation speeds when the clutch-to-clutch downshift is carried out during coasting of the vehicle, so that the vehicle is brought into a minimal driving state in which the engine speed is slightly higher than the output rotation speed of the fluid coupling device.

摘要： ECU executes a program including the step (S108) of setting a B2 brake to a engaging state when a first speed gear is effected (YES at S100) and when the difference between an output shaft rotation speed NOUT (1) estimated from an input shaft rotation speed NIN and the detected output shaft rotation speed NOUT (2) is larger than a threshold N (0) (YES at S106). When the B2 brake is in an engaged state, the relative rotation between the inner race and the outer race of one-way clutch is limited.

摘要： An overflow tube is provided at an oil pan and when the oil pan receives an amount of a working fluid exceeding a prescribed amount the overflow tube causes the fluid to overflow to allow the fluid to have a level set at a prescribed level. The overflow tube has an end portion positioned in the oil pan and defining an opening of a drain hole receiving and passing the fluid overflowing. The end portion has a curved surface facing vertically upward and extending to surround the opening of the drain hole, and curving in a direction in contact with a generally horizontal direction. The overflow tube can thus help to set the fluid's level at a prescribed level precisely.

摘要： In a friction engagement device of an automatic transmission, a brake piston is actuated by an oil pressure and a friction disc is pressed by the brake piston. The friction engagement device of an automatic transmission includes an oil pressure chamber extending in an annular shape and a main oil pressure supply path and a secondary oil pressure supply path each extending separately to supply oil to the oil pressure chamber. Each of the main oil pressure supply path and secondary oil pressure supply path connects to the oil pressure chamber in a position different from each other in a circumferential direction of the oil pressure chamber. With a construction as such, a friction engagement device of an automatic transmission is provided which prevents a load to the friction disc from locally increasing and attains a smooth speed-changing operation.
