A method for managing transmission information in a vehicle is provided to manage information of an automatic transmission of the vehicle integrally by attaching an RFID(Radio Frequency) system including an RF memory chip to the transmission, and storing information of a solenoid valve to the RF memory chip through communication between a TCU(Transmission Control Unit) and the RF system. A solenoid valve(60) of a valve body(40) of an automatic transmission is operated by directing current and hydraulic values corresponding to a shift pattern to a TCU(10) based on a hydraulic calibration program of a tester(20). Offset and gain values are found by a difference between hydraulic pressure, which is required by the difference between the solenoid valve and the valve body, and real hydraulic pressure. The offset and gain values are stored to an RF memory chip of an RF system(50) attached to the valve body of the automatic transmission. Information stored in the RF memory chip is transmitted to a transceiver(30) of the tester. |
