Changing the gearbox oil is an important procedure that can significantly affect the lifespan and performance of your car, whether you drive a vehicle with a manual or automatic transmission.

In this article we will cover every important aspect related to the need to replace it.

The importance of regularly changing gearbox oil

Regular gearbox oil changes are essential for keeping the transmission in excellent condition. It plays a key role in protecting the mechanical parts of the gearbox by reducing friction between them. If this friction is not controlled, it can lead to premature wear and damage to components.

Over time, the oil loses its lubricating properties and simply topping it up is not an appropriate solution. Using old or worn oil can reduce its effectiveness and fail to provide the necessary protection. Therefore it is especially important to check it regularly and replace it when necessary to ensure the transmission continues to operate smoothly and delivers optimal vehicle performance.

Furthermore, the change not only extends the life of the gearbox, but also helps maintain high shifting efficiency, ensuring smoother and quieter driving.

When and how to change gearbox oil?

The question of "when" to change the oil in your gearbox depends on several factors, including the type of transmission, driving conditions and the manufacturer's recommendations.

Change intervals by gearbox type

Here are some general guidelines from our specialists at OnDrive:

• manual – the generally accepted recommendation is to change it every 100,000 kilometers. This ensures that mechanical components remain well lubricated and protects against their premature wear;

• automatic – it is recommended to perform the change at shorter intervals – every 60,000 kilometers. Automatic transmissions are more complex and often require more frequent replacement due to higher operating temperatures and greater loads.

By following these recommendations, you can minimize the risk of costly repairs and keep your car in optimal condition for a longer period of time.

Procedure for changing

The change procedure is an important process that helps maintain the vehicle in good technical condition. Here are the main steps you should follow:

1. Check the level and condition

   This includes checking whether the oil is contaminated and whether its level is adequate. The check is performed using the dipstick.

2. Draining the old oil

   After you have checked and determined that it needs to be replaced, the next step is draining the old oil. This is usually done by opening the drain plug located at the bottom of the gearbox. Be sure to place a suitable container underneath to collect the drained transmission fluid.

3. Replace the oil filter, if necessary

   In some cases, in addition to changing the oil, the oil filter may also need to be replaced. This depends on the type of transmission and the manufacturer's recommendations. Check your vehicle's technical documentation for more information.

4. Adding new oil

   After you drain the old oil and replace the filter, proceed to add the new oil. Make sure you use the exact type specified by your car's manufacturer. It is added through the special filling opening, and it is important to follow the instructions regarding the required quantity.

Resetting the mileage counter at the end is extremely useful for maintaining the vehicle's regular service schedule. This practice helps owners track when the last oil change was performed and when the next one is due. If you prefer this procedure to be carried out by a specialist, you can see how much the service costs at our Varna workshop on our website.

Regular checks and potential problems

To prevent costly repairs, regular checking of the gearbox oil is mandatory. It includes checking its level and quality and looking for signs of contamination or metal shavings in it. Among the symptoms that indicate the need for a change are the following:

• noise when changing gears – if you hear unusual noises or grinding when shifting between gears, this may be a sign that the oil has lost its lubricating properties and does not provide sufficient protection against friction of the mechanical parts;

• difficulty shifting gears – if you feel that gears are not changing smoothly or the gears are "slipping", this may indicate that the oil is old or insufficient. Insufficient viscosity or reduced volume can impede the normal operation of the vehicle;

• unpleasant smell – if you detect a burnt or chemical smell, this is often a sign of transmission overheating or oil oxidation, which leads to loss of protective and lubricating properties.

Regular replacement is essential for the longevity and efficiency of the vehicle. Do not ignore these guidelines so that your car serves you reliably and you avoid unnecessary and large repair costs. By following the replacement and regular inspection recommendations, you are investing in the reliability and safety of your vehicle.
