摘要： An automatic transmission includes a gear transmission mechanism with first and second friction mechanisms which are alternatively engaged by alternative supply of first and second actuating pressures thereto when the highest speed stage and the next to highest speed stage are alternatively engaged, and a torque converter including a lockup clutch. A transmission control system includes a pressure control system which controls the gear transmission mechanism by selectively supplying those actuating pressures and possibly others, and a lockup clutch control valve which controls the engagement of the lockup clutch. The lockup clutch control valve is switched to its disengage position when it receives neither a first nor a second control pressure, and is switched to an opposite position by supply of either the first or second control pressure, this opposite position being an engage position for the lockup clutch if governor pressure is over a first specified value. The first control pressure is provided when governor pressure is higher than a second specified value higher than the first specified value and also the first actuating pressure is present; and the second control pressure is provided, if governor pressure is over the first value, when the throttle pressure is lower than a third specified value and also the second actuating pressure is present.

摘要： A torque converter includes a coaxially mounted pump impeller (6), turbine (7), and stator (10), each of which includes an outer shell (6A, 7A, 10A), an inner shell (6C, 7C, 10C), and vanes extending between the outer shell and the inner shall having edges which define an inlet (6i 7i, 10i) and outlet (6E, 7E, 10E). The pump impeller outlet (5E), is proximate to the turbine inlet (7i), the turbine outlet (7E) is proximate to the stator inlet (10i), and the stator outlet (10E) is proximate to the pump impeller inlet (6i). The outer and inner shells cooperate to define outer and inner toroidal surfaces, which together define a hollow toroidal hydraulic fluid circulation path. The ratio between the axial extent (L) and the radial (H) extent of a section of the outer toroidal surface is less than approximately 0.9. The axial distance between the general axial position of the edges of the stator vanes which define the stator inlet and the axial position of the edge of the stator inner shell in the direction of the stator inlet is substantially greater than zero (10BF), and the stator vanes which define the stator inlet extend more towards the direction of the turbine outlet (7E) than does the edge of the stator inner shell (10CO) in the direction of the stator inlet (10i).
