摘要： A transmission case has a wall portion defining an oil pressure chamber of a fluid operated friction device, and an end portion having a threaded hole receiving a bolt for fastening a side cover to the case. In order to make the wall portion impervious to oil notwithstanding defects formed by casting, the wall portion is separated from the end portion by a U-shaped groove. Furthermore, the end portion is shaped into an outward flange through which the threaded hole passes from one side to the other.

摘要： In an automatic transaxle having an idler gear center axis below a line interconnecting a main power train center axis and a differential center axis, a control valve assembly is disposed on one of opposite sides of a transaxle case divided by the idler gear center axis. The differential is disposed on the other of the opposite sides of the transaxle. An oil storing chamber is disposed next to the control valve assembly and free from occupation by same. The oil storing chamber extends from one to the other of the opposite sides of the transaxle case.

摘要： A single sequence valve is connected to a 3-4 shift valve thereby defining a drain circuit. The sequence valve is responsive to hydraulic pressures which act on a fourth speed apply chamber of a band brake and a high clutch, respectively. The sequence valve normally defines the drain circuit, but delivers hydraulic fluid to the 3-4 shift valve, then to the fourth speed apply chamber of the band brake after a command for a 4-2 downshift has taken place until the hydraulic pressure in the high clutch drops to a predetermined value.

摘要： An accumulator designed to alleviate a so-called N-D select shock is connected in a hydraulic control system for an automatic transmission such that it can also alleviate a 3-4 shift shock. The accumulator includes a piston and a spring biasing the piston. The spring force of the spring is appropriately set such that the piston starts moving against the spring in response to small pressure build-up of a drive range select pressure.
