The invention discloses a gear selecting and shifting force transducer calibration method. The method comprises the following steps: 1, scribing a marking line on a gear shifting head; 2, installing a gear selecting and shifting force transducer onto a calibration rack; 3, applying voltage to a strain bridge; 4, successively adding weights to a weight disc of the calibration rack; 5, rotating the gear selecting and shifting force transducer, thereby applying pressure to each monitoring channel in the gear shifting head, and repeat step 3 and step 4; 6, establishing a calibration model, conducting calculation, and obtaining calibration coefficients; 7, repeating step 3 to step 6, and verifying the accuracy degree and repeatability of a calibration result. By means of the method, the gear selecting and shifting force transducer can be calibrated rapidly and accurately.
