Control apparatus for hydraulically operated vehicular transmission.

摘要

In a control apparatus for a hydraulically operated vehicular transmission (1) which has a plurality of hydraulic engaging elements (C1 - C4), an orifice (30) is disposed in an oil passage (L2) which is communicated with a hydraulic engaging element (C1) for a low-speed transmission train (G1). The control apparatus has a bypass passage (L2b) which bypasses the orifice (30), a control valve (13) which can be changed over between a communicated state in which the bypass passage (L2b) is in communication and a cut-off state in which the communication of the bypass passage (L2b) is cut off, and a control circuit (10) which changes over the control valve (13) to the communicated state under a predetermined condition at a time of changing over from a running range (D) to a neutral range (N).
