What Are the Reasons for Vibration When Shifting to Reverse Gear in an Automatic Car?

[JohnnyRose]

When shifting gears in an automatic car, there is usually some vibration because the clutch differential is engaged, and the engine is generating torque. Minor vibrations are normal, but if the shaking is severe. Possible reasons include: 1. Low idle speed. 2. Dirty throttle body. 3. Dirty fuel injectors. 4. Severe engine carbon buildup. 5. Poor spark plug performance. There are three main reasons why an automatic transmission may not move when shifted to reverse gear: 1. Improper adjustment of the shift lever. 2. Leakage in the reverse gear hydraulic circuit. 3. Slippage in the reverse and high gear clutch or low gear and reverse gear brake. The damage to these three components is primarily caused by incorrect driving habits and the lack of regular inspection and maintenance. Incorrect operation can lead to premature wear of internal components in the automatic transmission, while the absence of regular vehicle inspections and maintenance prevents the detection of impurities in the automatic transmission fluid, further accelerating component wear.
