Will the Car Shake if the Transmission Mount is Broken?
2 Answers
Shaking occurs during gear shifting. Symptoms of a broken transmission mount include: 1. Shaking and jerking during gear changes; 2. Abnormal noises when starting or reversing the vehicle; 3. Severe cases may lead to damage to the transmission or chassis components. More details are as follows: 1. Reasons for timely replacement: The transmission mount protects the transmission from bumps during operation. It is a rubber product that prevents vibrations generated during transmission operation from being transmitted to the vehicle body. Over time, the transmission mount will age, and once it hardens, its ability to filter vibrations decreases. Therefore, it must be replaced promptly when aging occurs. 2. Consequences of not replacing: After aging occurs, driving safety is not immediately compromised in the short term. However, prolonged failure to replace it can lead to component failures, affecting driving safety.
As someone who frequently drives manual transmissions, I can tell you that a broken transmission mount will definitely cause the car to shake. That mount acts like a shock absorber, sandwiched between the transmission and the chassis, specifically designed to absorb vibrations. Once it wears out or cracks, the weight and movement of the transmission lose their support point, and the vibrations are directly transmitted into the body. It's most noticeable when you start the engine or idle—the steering wheel and seats shake as if you're sitting on a massage chair. If ignored, the shaking will worsen and could damage the transmission itself or other engine mounts, making repairs even more expensive. I recommend getting it checked at a professional auto shop sooner rather than later—don't wait for a small issue to become a big one, as it's both unsafe and costly. During routine maintenance, have the mechanic inspect the condition of the transmission mount to extend its lifespan. Remember, the health of your transmission affects overall driving smoothness—shaking is a warning sign.
