What Causes the Car to Shake When Shifting to D Gear?

Shifting to D gear causes the car to shake for the following reasons: 1. The engine speed is too high: When the engine is cold and just started, the engine speed is too high, and the torque converter transmits more power, resulting in greater impact force and more noticeable shaking when shifting to D gear. 2. The brake is not pressed firmly: At the moment of shifting, the engine power is directly transmitted to the wheels. If the brake is not pressed firmly, the wheels will move slightly when shifting to D gear, and the car will suddenly move forward, causing a stronger shaking sensation. 3. The brake is released too early: This causes abrupt power engagement. Without the limiting effect of the brake, the drive wheels suddenly receive power at the moment of gear engagement, causing the car to move forward directly and resulting in shaking.
