Millisecond shift response: the shift time is less than 0.2 seconds, the power connection is not frustrated and the driving comfort is improved. Ultra-long service life: the service life can reach 2 million kilometers, which has been verified by the "three highs" limit test of cold, plateau and high temperature. Fault self-diagnosis system: Built-in sensors monitor parameters such as gearbox temperature and oil pressure in real time, and provide fault warning when there is abnormality, thus improving driving safety. Full scene mode: integrate various driving modes such as economy, sports, snow, off-road and so on, and switch with one button to adapt to different road conditions. The transmission efficiency is as high as 99.8%, which allows the engine power to be transmitted to the wheels more directly.
