Signs Of A Broken Gearbox Car

The transmission is an important part of the vehicle's speed regulation. After many years of use, like any other part, the gearbox will reach the limit and start to cause illness, especially old cars. And then, the driver needs to recognize the signs to have the car repair and maintenance plan in time.

The first sign is that the gear lever is very hard, difficult to control, so that the gear cannot be installed. A common cause is low lubrication oil level due to leakage or unsure viscosity due to expiry date or dirtyness. Unlike machine oil, gearboxes do not consume oil during operation, so if you check that the engine oil level is low, then the oil has leaked out. For such cases, please take the car to check immediately because gearbox oil plays an important role in the operation of the vehicle.

The next sign is a burning smell, which indicates that the gearbox is overheated, causing the gear oil to burn and work inefficiently. Gearbox oils not only lubricate gears, they also cool by continuously circulating heat when shifting gears. On some models, the gearbox also has a separate oil cooler for easier heat dissipation. You can easily overcome the phenomenon by changing gear oil. Another cause of a bad smell is because you use an improperly tapered foot, causing the cheeks to become large in friction and start to produce a strong smell. However, this odor will disappear quickly if the driver adjusts his driving style.

Too noisy gearbox is also one of the symptoms. This must be very sensitive driver to recognize. However, when it was discovered that the transmission was louder than usual, it was because of bearings, gaskets or worn gears.

Another sign is that the engine test light is on. Although this light only lights up when there is any damage to the engine and the vehicle's transmission system, it can also let you know when the transmission has a problem. To find out the exact cause, you can buy the device to read fault or take the car to the service center for inspection.

The next phenomenon is the digital slip, which leads to events beyond the control of the operator or the computer. Like setting a wrong number, sliding a gear often results in a car shock, or an engine roar. It often causes the driver to lose his temper and easily cause an accident.

Finally, stick. In this case, though the clutch pedal has hit the floor, the gearing is still difficult, accompanied by a hiss. The unreleased clutch makes it difficult for the gear pairs to match because they are not yet in sync, the friction disc slips on the flywheel and the pressed disc creates a shrill sound. The cause is usually derived from the clutch transmission system does not create enough separation force because the cables are already dead, the journey is too large ...

According to the driver's experience, any time you discover one of the above symptoms, you should take your car to a repair garage or a reputable service center to perform maintenance.
