10 signs of gearbox failure

Transmission failures can be easily detected when the vehicle is running thanks to various signs.

1: Cannot change number.

Although the structure is simpler than the automatic transmission, the manual transmission also has some common problems. One of them is the phenomenon of not being able to change gears, even though the driver has released the clutch and pushed the lever. This can happen both when shifting from “neutral” to 1st gear, and when shifting between different gears.

The causes of this phenomenon are usually low gear oil, using the wrong gear oil consistency and incorrect clutch adjustment.

2: There is a burning smell.

A burning smell indicates that the transmission is overheating, causing the transmission fluid to start burning and not working properly. Transmission fluid not only lubricates the gears, it also acts as a coolant by continuously circulating the heat generated when shifting gears. On some models, the transmission also has a separate oil cooler to help dissipate heat more easily. You can easily fix this problem by changing the transmission fluid.

Another reason that can lead to a burning smell on a manual transmission vehicle is improper use of the clutch, causing the clutch plates to have too much friction and start to produce a burning smell. However, this smell will quickly disappear if the driver adjusts his driving style.

3: The car is noisy when in "mo".

An unpleasant noise when idling can again indicate that the transmission fluid is due for a change, or it can be a sign of more serious mechanical damage. However, most often the noise is caused by worn bearings or gears in the transmission that need to be replaced.

4: Slide the number.

If it’s working properly, the transmission will continue to operate in the gear you want, or the computer will automatically shift gears when you reach a certain rpm to save fuel. However, if the transmission is slipping, it can jump into different gears, or into “neutral” with a manual transmission.

This is a dangerous symptom, as you may lose control of the car when you need to get out of an emergency situation. Therefore, you should immediately take the car to a repair shop to quickly fix the gearbox.

5: Cone does not cut.

This is another symptom that often “haunts” manual transmission drivers. Even though they fully depress the clutch pedal, the clutch still does not disengage completely, and the clutch plates continue to press against the flywheel, causing unpleasant noises when shifting gears.

Fortunately, however, this symptom is quite easy to fix without costing the car owner too much: just readjust the clutch pedal travel, and everything works smoothly again!

6: Transmission oil leak.

Transmission fluid leaks are one of the easiest ways to detect a problem with your transmission. On automatic transmission vehicles, transmission fluid is vital to the vehicle’s performance. So if you notice drops of fluid under your vehicle, have it checked out right away. Unlike engine oil, transmissions don’t consume fluid as they operate, so if you notice a lack of fluid, it’s a sure sign that there’s a leak.

7: Check engine light is on.

While this light can come on when there’s something wrong with your car’s engine and transmission, it can also indicate that there’s a problem with your transmission. To find out exactly what’s causing this light, you can buy a diagnostic tool that’s readily available on eBay or take your car in for a service.

8: The gearbox is noisy and vibrates.

Depending on whether your car has a manual or automatic transmission, your transmission can show signs of trouble in different ways. As mentioned above, manual transmissions often make a grating noise when shifting gears, even when the clutch is fully disengaged. This can happen when the clutch is worn out, or when the gears in the transmission are damaged.

On an automatic car, if your car doesn't shift smoothly as usual and vibrates or shifts with difficulty, you need to have your car checked immediately.

9: Strange noises.

It’s hard for a single driver to know exactly where the transmission is going wrong, but you can at least tell that there’s a problem with your five senses. Every car is made differently, so the sounds they make when their transmissions are going wrong are different. However, automatic transmissions tend to make a whistling or even a short whine, while manual transmissions tend to make more “mechanical” sounds.

10: Lack of sensitivity.

Transmissions are designed to shift gears precisely, so if they seem to be working less efficiently than usual, you can be sure that there is a problem. On a manual transmission, you can notice this when you shift gears and the engine revs up, but the car still feels sluggish. This is usually a sign of worn clutch plates.

Automatic transmissions also have sluggish symptoms, but it only shows when shifting into Park or Drive mode. Normally, the transmission will quickly shift into these two modes, but if you find it difficult to do so, it is best to take the car to a familiar garage for inspection and repair./.
