ABSTRACT:
An infinitely variable belt-drive transmission is provide with a D/L-range as one of operating ranges. The system has a transmission ratio control valve comprising a spool which is moved in the downshift direction to downshift the transmission and in the upshift direction opposite to the downshift direction to upshift the transmission. An actuator is provided for moving the spool. When an accelerator pedal of a motor vehicle is depressed at the D/L-range, the actuator operates to move the spool in the downshift direction and when the accelerator pedal is released at the D/L-range, the actuator operates to move the spool in the upshift direction.
