Abstract

PURPOSE: To prevent surely unintentional lockups likely when shifting up to the positions which have potential of lockup, by producing solenoid pressure in a position a step below the position that has potential of lockup.
CONSTITUTION: A lockup control valve 209 is so arranged that it can be controlled by a solenoid valve 420 in No.2WNo.4 position and not controlled in other conditions. To an oil chamber 294 in the lockup control valve 290, the line pressure introduced from oil line 104 through an orifice 422 is supplied all the time s solenoid pressure to be controlled by the solenoid valve 420 to depress spools 292, 293 together with a spring 291 and when, in No.2 position or above, the spool 222 of the 1-2 shifting valve 220 is set to the left, the line pressure is supplied to the oil chamber 295 through oil line 113 to apply heaving pressure to the spools 292, 293.
