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： In a shift control system of an automatic transmission for a vehicle, an engaging torque applied to a predetermined friction element that has been engaged to establish a predetermined gear stage of the automatic transmission during running of the vehicle is gradually decreased to generate a slip in the predetermined friction element. Based on the engagigng torque of the friction element and a command value output to generate the engaging torque to the friction element, a predetermined relationship used for determining the command value for generating a required engaging torque is corrected. Learning quality or accuracy with respect to the predetermined relationship between the engaging torque of the friction element and the control value for generating the engaging torque may be sufficiently ensured.

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： 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.
