The car that came to the store to repair the gearbox today was a 2016 Dongfeng Popular SX6 car with a displacement of 1.6L and equipped with an infinitely variable transmission (CVT). According to the owner, the number of kilometers traveled has reached nearly 100,000 kilometers, and it is in gear and does not move. phenomenon.

Therefore, during the daily maintenance of the car, the safety issue of the automatic gearbox must not be ignored.
