PURPOSE:To provide the hydraulic controller of a belt type continuously variable transmission for vehicle which is free from the slip of a transmission belt in the reverse revolution of a variable pulley. CONSTITUTION:When it is judged that a shift lever 126 is operated to an advance traveling range, during retreat traveling, the third solenoid valve 103 and the first linear solenoid valve 105 are set into a turned-ON state for a prescribed time, and the second line pressure Pl2 is increased, and the slip of a transmission belt 70 in the reversal in the revolution direction of the variable pulleys 66 and 68 is prevented. |
