1. An input torque detecting system of an automotive transmission comprising a torque converter having a pump impeller directly connected to a crankshaft of an engine, a turbine runner disposed opposing to the pump impeller to rotate by fluid thrown from the pump impeller, and a stator disposed between the pump impeller and the turbine runner to redirect the fluid flow back to the same direction as impeller rotation to assist impeller rotation, the input torque detecting system comprising:

  • a reacting shaft disposed around the input shaft and fixed on one end to the stator;

    an input torque transmitting device fixed on the other end of the reacting shaft, the input torque transmitting device being pivotable by a predetermined angle and operating by a predetermined distance synchronously in accordance with a rotation of the stator;

    a torque-hydraulic pressure converter converting input torque transmitted from the input torque transmitting device into hydraulic pressure; and

    a detector detecting a level of converted hydraulic pressure,wherein the torque-hydraulic pressure converter comprises a valve body having a first passage supplied with hydraulic pressure from a hydraulic source and a second passage supplying hydraulic pressure to the detector.
