Why does the car shake when shifting into reverse gear?

[AndresAnn]

The reason the car shakes when shifting into reverse gear is due to insufficient or dirty transmission oil. When shifting into reverse gear, fully depress the clutch pedal to completely disconnect the power output between the engine and the transmission. Then, shift into reverse gear gently to avoid severe gear grinding. Precautions for shifting into reverse gear include: 1. Come to a complete stop: Always ensure the vehicle is fully stopped before shifting into reverse gear. Since the power direction needs to change when shifting into reverse, failing to stop the vehicle completely can cause gear grinding. 2. Go slow: Always reverse slowly. Because the reverse gear uses straight-cut gears, the power transfer is very direct, and reversing too fast can produce loud whining noises.
