3 Harmful Effects of Not Changing Gearbox Oil Regularly and Early Warning Signs

Train oil plays an essential role in lubricating, cooling and ensuring smooth operation of the entire transmission system.

However, many drivers still do not really care about changing transmission oil periodically. Delaying maintenance can have serious consequences for your vehicle. The article below will point out 3 common harmful effects and warning signs you should not ignore.

1. Reduced transmission efficiency

Gearbox oil after a period of use will oxidize, become contaminated with dirt and lose its lubricating properties. At that time, the gearbox operates inefficiently, leading to:

The vehicle shifts slowly, jerkily or not smoothly.

The engine rpm is high but the car accelerates slowly.

Consumes more fuel because the gearbox has to work harder.

If you notice that the car often "screeches" when accelerating or has a large delay when shifting gears, it is a sign that the transmission oil has degraded.

2. Causes wear of gearbox parts

Gearbox oil not only lubricates but also helps cool and protect mechanical parts from friction and high temperatures. When the oil loses its effectiveness:

The gears in the gearbox wear out quickly.

Strange noises, hissing, or grinding appears from the transmission compartment.

Risk of damage to electric valve assemblies, oil pumps or control circuits.

Failure to change the oil on time can cause transmission repair costs to reach tens of millions of dong, or even require a complete replacement.

3. Reduces gearbox life

The transmission is one of the most valuable parts on the vehicle. A transmission that is damaged due to not changing the oil promptly will:

Unstable operation, easily overheating.

Leads to gearbox error, loss of control signals or incorrect gear shifting.

Shortens vehicle life and reduces resale value.

Regular oil changes not only help the vehicle run smoothly but also prolong the overall life of the transmission system.

Warning signs that you need to change transmission oil soon

Don't wait until the transmission has problems to check the oil. Pay attention to the following signs:

Gearbox oil changes color, has a burning smell or is cloudy.

The vehicle jerks and vibrates when entering gear or shifting gears slowly.

There is a strange sound coming from the gearbox when operating.

The transmission warning light displays on the dashboard.
