ABSTRACT:
The present invention discloses a control apparatus for an oil pressure operated transmission in an automotive vehicle. The apparatus comprises a transmission with at least two stages of low speed and high speed forward driving trains and it is so arranged that, in an automatic shift range of a manual valve connected through first oil passage to an oil pressure source, low speed and high speed oil pressure clutches are selectively supplied with pressure oil through a shift valve in communication with the manual valve through a second oil passage. In a hold range of the manual valve, the valve is interposed between the low speed oil pressure clutch and the shift valve means for dividing the oil passage into third oil passage on its upstream side and fourth oil passage on its downstream side, having no communication between third and fourth passage and establishing a communication between fourth and first oil passage without through the shift valve means. At the same time the communication between first and second oil passage is disrupted.
