What Causes Body Vibration When Shifting to Reverse Gear in Automatic Transmission Vehicles?

[LaAdam]

Here are the specific reasons for body vibration when shifting to reverse gear in automatic transmission vehicles: 1. Worn engine mounts: Engine mounts are used to dampen the vibrations produced by the engine. When shifting into reverse gear, the engine and transmission are connected, and if the mounts are worn, engine vibrations can be transmitted into the cabin. 2. Faulty spark plugs: Faulty spark plugs can cause engine misfires, leading to uneven power output and increased vehicle vibration. 3. Overly rich air-fuel mixture in the cylinders: An overly rich air-fuel mixture can cause the vehicle to shake, especially when shifting into reverse gear, making the vibrations more noticeable inside the cabin.
