Abstract
PURPOSE: To enable speed change in a range where a throttle valve is widely opened, by making a detent pressure counteract a throttle pressure applied to a top speed change gear valve and actuating a valve body of said valve under the detent pressure and a governor pressure when the detent pressure is applied.
CONSTITUTION: A speed change controller is provided with a pressure rgulating valve 42 for controlling an oil pressure formed by an oil pump 41, a throttle valve 45 for generating an oil pressure according to openings of a throttle valve, a governor valve 54 for generating an oil pressure according to speeds of a vehicle, and a speed selecting valve 44 for manually shifting gears of a transmission. Also, the speed change controller inculdes the first-to-second speed change valve 56, the second-to-third speed change valve 57, an over-drive control valve 58 and a detent valve 46 which outputs a detent pressure to operate each valve 56W58 at kick- down. In near terms, when the throttle valve is fully opened during overdriving, the detent pressure is carried into an input port 103 of the valve 58 through a passage 100d to move down a valve body 74 against a throttle pressure.
