摘要： A direct-coupling controller for a torque converter direct-coupling clutch in an automatic transmission. The controller includes a pilot oil pressure operated timing valve which interconnects the hydraulic cylinders of at least two of the hydraulically operated friction elements of the transmission to the hydraulic-cylinder of the direct-coupling clutch. The timing valve has two positions, a first where one of the friction elements is connected to the clutch and a second where the other is. Structure can be provided to delay movement of the timing valve spool member for a predetermined time. Additionally, a reduction valve can be interposed between the timing valve and the clutch to keep the oil pressure to the clutch at a predetermined level. A vehicle speed response valve can also be interposed between the timing valve and the clutch in parallel with the reduction valve to bypass the reduction valve when the vehicle speed exceeds a predetermined value.
