Car Shaking Transmission
Causes of a Shaking Transmission
There are a number of potential causes for a shaking transmission. Some of the most common include:
- Worn or damaged transmission mounts. The transmission mounts connect the transmission to the frame of the vehicle. If these mounts are worn or damaged, they can allow the transmission to move, which can cause shaking.
- Low transmission fluid. Transmission fluid lubricates the transmission and helps to keep it cool. If the transmission fluid is low, it can cause the transmission to overheat and shake.
- Damaged torque converter. The torque converter is a part of the transmission that helps to transmit power from the engine to the transmission. If the torque converter is damaged, it can cause the transmission to shake.
- Faulty transmission solenoid. The transmission solenoid is a part of the transmission that controls the flow of transmission fluid. If the solenoid is faulty, it can cause the transmission to shift erratically, which can lead to shaking.
- Damaged transmission gears. If the transmission gears are damaged, it can cause the transmission to grind and shake.
Symptoms of a Shaking Transmission
The symptoms of a shaking transmission can vary depending on the cause of the problem. Some of the most common symptoms include:
- Shaking or vibration when the vehicle is in gear. The shaking or vibration may be most noticeable when the vehicle is accelerating or decelerating.
- Difficulty shifting gears. The transmission may be difficult to shift into or out of gear, or it may grind when shifting.
- Leaking transmission fluid. A leak in the transmission can cause the transmission fluid level to drop, which can lead to shaking.
- Overheating transmission. The transmission may overheat and cause the vehicle to stall or go into limp mode.
Diagnosing a Shaking Transmission
Diagnosing a shaking transmission can be a complex process. The mechanic will need to perform a number of tests to determine the cause of the problem. These tests may include:
- Visual inspection. The mechanic will visually inspect the transmission and its components for any signs of damage.
- Fluid level check. The mechanic will check the transmission fluid level and condition.
- Road test. The mechanic will take the vehicle for a road test to experience the symptoms firsthand.
- Computer diagnostic scan. The mechanic may use a computer diagnostic scanner to retrieve trouble codes from the transmission control module.
Repairing a Shaking Transmission
The repair for a shaking transmission will depend on the cause of the problem. In some cases, the repair may be as simple as replacing the transmission fluid or tightening the transmission mounts. In other cases, the repair may be more complex, such as replacing the torque converter or rebuilding the transmission.
It is important to have a shaking transmission repaired as soon as possible. If the problem is not addressed, it can lead to further damage to the transmission and other components of the vehicle.
Preventing a Shaking Transmission
There are a number of things you can do to help prevent a shaking transmission. These include:
- Regularly check the transmission fluid level. The transmission fluid level should be checked every few months, or as recommended by the vehicle manufacturer.
- Keep the transmission cool. Avoid driving in excessively hot conditions, and do not tow heavy loads for extended periods of time.
- Have the transmission serviced regularly. The transmission should be serviced according to the vehicle manufacturer’s recommendations. This will help to keep the transmission in good working condition and prevent problems from developing.
By following these tips, you can help to prevent a shaking transmission and keep your vehicle running smoothly.
