    Abstract: The present invention relates to a manual valve of an automatic transmission, having a groove formed at an exterior surface thereof so as to reduce shock and to improve shift feel by allowing oil to flow through the groove when releasing hydraulic pressure. An exemplary manual valve of an automatic transmission includes a valve body and a valve spool slidably provided in the valve body. The valve body includes a spool receiving part, a first port, a second port, and a third port. The valve spool includes an underdrive land assembly and a reverse land assembly, wherein at least one of the underdrive land assembly and the reverse land assembly has a groove formed on an exterior circumference thereof along a sliding direction of the valve spool such that oil flows therethrough when hydraulic pressure is released.

    Abstract translation: 本发明涉及一种自动变速器的手动阀，其具有在其外表面形成的槽，以便在释放液压时允许油通过槽流动来减少冲击并改善换档感。 自动变速器的示例性手动阀包括阀体和可滑动地设置在阀体中的阀阀芯。 阀体包括线轴接收部，第一端口，第二端口和第三端口。 阀芯包括欠驱动平台组件和反向平台组件，其中，低驱动平台组件和反向平台组件中的至少一个具有沿着阀芯的滑动方向在其外圆周上形成的凹槽，使得油流过其中 当液压被释放时。
