Control apparatus for hydraulically operated vehicular transmission

摘要

A control apparatus for a hydraulically operated vehicular transmission includes a orifice, a bypass path bypassing the orifice and a switching valve provided in the bypass path. The orifice and bypass path are provided in an hydraulic oil supplying path to a hydraulic pressure coupling element provided in said hydraulically operated vehicular transmission. The switching valve shuts off said bypass path in association with the throttle of an engine at a low opening time when a throttle opening degree is equal to or lower than a first predetermined value and at a high opening time when the throttle opening degree is equal to or higher than a second predetermined value which is higher than the first predetermined value.
