What causes the sudden shift from D to N gear while driving?
1 Answers
The reason for the sudden shift from D to N gear while driving is: a mismatch between the automatic transmission control unit and the gearbox. The main functions of a car's transmission are: 1. Changing the transmission ratio to meet the traction needs under different driving conditions; 2. Enabling reverse driving; 3. Interrupting power transmission to the drive wheels when the engine starts, idles, shifts gears, or needs to stop for power output. Maintenance methods for the transmission include: 1. Regularly checking the fluid level; 2. Avoiding skipping gears when upshifting; 3. Not forcing the transmission into neutral; 4. Not shortening the idle warm-up time; 5. Avoiding gear grinding when shifting. Precautions for changing transmission fluid include: 1. Selecting the appropriate viscosity to prevent power loss; 2. Using qualified transmission fluid; 3. Ensuring no impurities are introduced during the fluid change.
