Abstract

PURPOSE: To reduce fuel cost by establishing a fix-forward staged speed change with independent shift valves provided for those speed change actions performed by means of a two-forward stageed auxiliary speed change gear and a three-forward staged main speed change gear.
CONSTITUTION: The automatic speed change gear has a fluid torque convertor 1, a two-forward staged auxiliary speed change gear and a three-forward staged main speed change gear. Shift of each speed change gear is performed by No.1WNo.3 shift valves 220, 230, 240 in an oil-pressure circuit, and thus a six-forward staged speed change is provided. The above oil-pressure circuit is provided with a throttle valve 200, which generates a throttle pressure conforming to the degree of throttle opening from the line pressure generated by a hydraulic pump 101, and controlled by a pressure control valve 102, a manual valve 210 by which manual shifting of speed range is performed, and No.1WNo.3 solenoid valves 430, 400, 410, which control the line pressure to be supplied to each shift valve 220, 230, 240.
