摘要：PURPOSE:To obtain a desired speed change gear line pattern by using a system in which another shift valve sending out a corrected throttle-corresponding pressure according to a governor pressure and a throttle-corresponding pressure is provided in addition to a shift valve which is affected by non-kickdown and kickdown conditions. CONSTITUTION:For a forward 3-speed and backward 1-speed type of automatic change gear, an oil-pressure controller consists of a 1-2 shift valve 3, a 2-3 shift valve 4, and a 3-2 down-shift valve 5. The 2-3 shift valve 4 is provided with a spool 4b such that it is moved in such a way that a governor pressure to be directed from a circuit 23 to a port 4t, a throttle-corresponding pressure to be directed from a circuit 38 to a port 4u, a throttle-corresponding pressure to be directed from a circuit 36 to a port 4x, and a kickdown pressure to be directed from a circuit 24 to a port 4s are balanced. Also, the 3-2 downshift valve 5 is provided with a spool 5h such that it is moved by said governor pressure and said throttle-corresponding pressure and sends out a corrected throttle-corresponding pressure to the circuit 36.
