    • A replacement forward clutch control valve assembly including a primary control land, which is designed to properly align the valve piston within its mating bore in the valve body of an automatic translate is disclosed. The primary control land has a substantially increased axial length in comparison to the original equipment manufacture valve piston without exceeding the overall length of the original valve piston. The present forward clutch control valve assembly provides a substantially improved control land-to-bore surface contact ratio and also provides a more durable end surface area for contact with the retaining clip during operation. As a result the present forward clutch control valve assembly is substantially less prone to bending and/or seizure within its mating bore during operation.
    • 公开了一种替换前进离合器控制阀组件,其包括主控制区域,其被设计成将阀活塞适当地对准其自动平移阀体内的配合孔内。 与原始设备制造阀活塞相比,主控制区域的轴向长度大大增加,而不超过原始阀活塞的总长度。 当前的前进离合器控制阀组件提供了显着改进的控制陆面到钻孔表面接触比,并且还提供了在操作期间与保持夹接触的更耐用的端面区域。 因此,在操作期间,当前的前进式离合器控制阀组件在其配合孔内基本上不易弯曲和/或卡住。

    • A method for controlling hydraulic pressure of an automatic transmission for a vehicle is provided. The automatic transmission has a clutch element engaged by a solenoid pressure to perform speed change. The solenoid pressure is generated by a solenoid that is driven by a solenoid drive current. The method calculates a required clutch engagement pressure and a required solenoid pressure corresponding to the required clutch engagement pressure based on a relationship between the clutch engagement pressure and the solenoid pressure. The method outputs a required solenoid drive current corresponding to the required solenoid pressure based on a relationship between the solenoid pressure and the solenoid drive current. The solenoid outputs the solenoid pressure corresponding to the required solenoid drive current.

    • An electro-hydraulic pump module (10) for controlling the upshifting and downshifting of an automatic power transmission. The pump module (10) includes a plurality of individual pumps (12, 14) each in communication with a fluid source (34). Each of the plurality of individual pumps (12, 14) is in fluid communication with a respective switching valve (44, 52). Each of the switching valves (44, 52) controls the flow of fluid from a respective pump to a friction element to accomplish a desired gearshift. The plurality of pumps (12, 14) and the switching valves (44, 52) are each in fluid communication with an electronic control module (70). The electronic control module (70) activates an appropriate one of the plurality of pumps (12, 14) and an associated switching valve (44, 52) to direct fluid to the necessary friction element to drive the transmission in the appropriate gear.
