What are the reasons for severe transmission vibration?
2 Answers
The reasons for severe transmission vibration are: 1. Excessive carbon deposits inside the engine, which absorb a certain amount of oil causing the air-fuel mixture to be too lean; 2. A dirty air filter leading to insufficient air intake; 3. Increased spark plug gap or excessive carbon deposits; 4. Aging engine mounts failing to provide proper damping. The functions of a transmission are: 1. To change the gear ratio and expand the range of torque and speed variation for the driving wheels; 2. To enable the vehicle to reverse while maintaining the engine's rotational direction; 3. To interrupt power transmission using neutral gear, allowing the engine to start, idle, and facilitating gear shifting or power output.
I often discuss transmission shudder with my friends, and this issue can be quite troublesome. If the transmission shakes severely, the root cause might be internal wear of the gear set or torque converter failure. For automatic transmissions, imbalanced oil pressure can also lead to vibrations; for manual transmissions, it's likely due to clutch slippage or synchronizer loosening. External factors like engine vibrations transferring over or an unbalanced driveshaft could trigger a chain reaction. Don’t underestimate it—prolonged neglect can worsen component damage. It’s advisable to first check the fluid level for adequacy and cleanliness. If the fluid turns black, it’s a warning sign—stop driving immediately and head to the repair shop. After all, delaying repairs could mean costly transmission overhauls, compromising driving safety and peace of mind.
