Abstract
PURPOSE: To get smooth drive without any shock caused by speed change by changing the hysteresis characteristic of a shift valve according to the stepping on speed of an accelerator pedal.
CONSTITUTION: A throttle pressure Pt is conducted between a land 122 and a land 124 of a spool valve 100 of a 2-3 shift valve 70 and the hysteresis characteristic of the 2-3 shift valve 70 is changed by feeding and discharging the throttle pressure Pt by means of a throttle pressure switching valve 62 operated by the differential oil pressure generated between an oil passage 58 and the oil passage 56 in the downstream side of an orifice 76, according to the stepping on speed of the accelerator pedal. In this way, even if the amount of stepping on the accelerator pedal is small, shift down is operated by discharging the throttle pressure Pt, in case of high stepping on speed even though driving speed is comparatively high and shift down is not operated in the reverse case.
