The differential is composed of planetary gear teeth, planetary gear carrier (differential housing), half shaft gear and other parts. The automobile differential has three functions: 1. Transmit the power output by the engine to the wheels; 2. Divide the increased torque of the main reducer into two parts and distribute it to the left and right half shafts; 3. As the main reduction gear of the automobile, reduce the speed of the transmission system before the power is transmitted to the wheels, transfer the power to the wheels, and allow the wheels on both sides to rotate at different wheel speeds. ① If the car can't drive, whether in R or D, it's probably due to oil leakage from the automatic transmission. At this time, you need to check the bottom of the car to see if there is red oil leakage. If so, it means that the transmission leaks oil. If the sealing ring is aging, as long as 2. ② abnormal upshift. If you feel that the speed before upshift is significantly higher than before (ECO mode / normal mode), or even upshift is not allowed, it is likely that the throttle cable or throttle position sensor is improper. Secondly, it is also possible that the speed sensor is faulty. First of all, we need to check one 3. ③ engine idling generally speaking, engine idling is divided into two situations, one is the instant of transmission
