What are the hazards of shifting into reverse gear before the car comes to a complete stop?

[AndrewDella]

Shifting into reverse gear before the car comes to a complete stop, if this erroneous operation is performed frequently, can easily cause wear and tear on the internal reverse gear of the vehicle's transmission. Here is some extended information: Gear grinding phenomenon: For manual transmission models, the reverse gear does not have a synchronizer, so when shifting into reverse gear, the gears engage directly. If the car is not completely stopped, shifting into reverse gear can easily cause gear grinding. Precautions: For automatic transmission models, this situation may cause wear on the internal friction plates of the transmission or damage to related retaining springs. Therefore, shifting into reverse gear before the vehicle comes to a complete stop is an incorrect operation method. It is important to develop good driving habits in the future.
