现代变速箱档位传感器 45956-28010 耐用原厂替代

Modern transmission gear position sensor (OEM 45956-28010) mounted on the side of the transmission housing, directly monitors the shift lever position and transmits gear signals to the ECU to ensure coordinated operation of engine and transmission. Fits Sonata, Elantra, Tucson, and many other models; OEM number 45956-28010. Replacement difficulty is moderate; estimated labor 1–1.5 hours, requires removal of transmission undertray and wiring harness plugs. If shifting jerks occur, the instrument cluster displays abnormal gears, or the vehicle cannot start (Park signal missing), the sensor has failed and should be replaced to avoid damage to the drivetrain.
