Abstract

PURPOSE: To prevent erroneous operation as well as to reduce the piece number of parts in such a way that an electronic circuit to emit output in proportion to each speed change stage is provided, one shift valve is controlled by a first solenoid valve, and two shift valves are controlled by a second solenoid valve.
CONSTITUTION: Arrangement is done such that a first solenoid valve 320 controls a two-to-three shift valve 230, and a second solenoid valve 330 controls a one-to- two shift valve 220 and a three-to-four shift valve 240. The first and second solenoid valves drain pressured oil in oil passages 111 and 112 by output in an electronic circuit to emit speed change signals in proportion to the vehicle running condition, and operate shift valve spools 232, 222 and 242. Such as this, since each shift is done by independent shift valve, it offers possibility of preventing erroneous operation with use of a valve stick, and because two solenoids control three shift valves, less piece number of parts is allowable.
