What are the symptoms of a broken transmission mount pad?
3 Answers
When starting the car, there will be shaking, and during driving, the stability of the car will be reduced. More relevant information is as follows: 1. If the transmission mount pad is damaged, it needs to be replaced immediately. If the transmission mount completely breaks during driving, the support force of the transmission will lose balance. 2. Whether it is an automatic transmission model or a manual transmission model, the transmission will cause abnormal gear shifting during operation. After the transmission mount is damaged, it will also cause jerking during the transmission's operation. The reason for this phenomenon is that the temperature of the transmission oil is too high, and impurities appear inside the transmission oil, causing jerking during the transmission's operation.
After driving for over a decade, I can tell you that a broken transmission mount is extremely noticeable. Especially during acceleration, the car vibrates like an earthquake, and the steering wheel shakes so violently it can make your fingers go numb. Sometimes when starting or braking, you'll hear weird creaking sounds, like old bones grinding. The ride becomes uncomfortable with increased bumpiness, making long drives even more exhausting. These mounts usually fail due to aging or excessive stress. If not repaired promptly, it may affect the transmission's position, leading to rough shifting or even damage to other components. For safety reasons, I immediately drove to a repair shop when I noticed the vibrations. I recommend having mechanics check the mounts during regular maintenance to prevent issues before they arise.
Symptoms of a broken transmission mount are quite noticeable, such as severe shaking of the car body or steering wheel during acceleration, a clear vibration sensation from the engine compartment, accompanied by clicking or rattling noises. Even at idle when parked, the noise is unusually loud. The main causes are rubber aging or vibration impact. Long-term neglect can lead to transmission misalignment and poor shifting feel. Inspection is straightforward: lift the car on a hoist and check for cracks or looseness in the mount. Replace the part promptly to avoid minor issues escalating—delaying can skyrocket repair costs. I've seen a friend's case worsen to transmission oil leakage, resulting in a hefty repair bill.
