Filed: 1985-12-11
Abstract: PURPOSE:To perform always stabilized transmission shift with varied oil pressure for transmission shift according to changes in loads on a vehicle by outputting signals to an actuator so that increasing oil pressure is obtained according to the increasing load on the vehicle. CONSTITUTION:Oil pressures in a line oil pressure passage 11 to which discharged oil from an oil pump 10 is supplied are regulated with a line pressure regulation valve 12.
