The invention relates to the technical field of engine gearbox early warning, and particularly discloses an engine gearbox early warning method and system and an intelligent networked automobile. The method comprises the following steps: acquiring a gear-shifting performance evaluation value, a gear-shifting impact evaluation value and a gear-shifting smoothness evaluation value of a gearbox at the current moment, further acquiring an early-warning judgment value of the gearbox at the current moment, and acquiring a monitoring judgment result of the gearbox at the current moment based on the early-warning judgment value of the gearbox at the current moment. And according to the monitoring judgment result of the engine and the gearbox at the current moment, an engine gearbox early warning result at the current moment is obtained. According to the method and the device, whether the running condition of the gearbox at the current moment needs to be pre-warned or not is accurately quantified, so that a more comprehensive and accurate engine gearbox pre-warning result is obtained, and potential fault problems of the gearbox and an engine can be found in time.
