To enjoy smooth driving and a long life for your automatic transmission, regular maintenance is not only desirable but necessary. In this article we will provide you with 5 useful tips on how to care for your automatic transmission and avoid serious problems.

1. Change the transmission fluid regularly

Changing the transmission fluid in the automatic gearbox is the first and most important step in its maintenance. This fluid plays an essential role in cooling and lubricating the mechanisms, and over time it becomes contaminated and loses its effectiveness. For most makes and models, it is recommended that the first change be carried out at around 80,000 to 100,000 km or after 5 years, after which it is good to change it every 50,000 km or every 3 years. Adhering to these intervals prevents symptoms such as slipping gears and delayed engagement.

For optimal maintenance of the automatic transmission, always use the manufacturer's recommended fluid and make sure that the change is accompanied by replacement of the filter and gasket. This preventive measure helps the gearbox run smoothly and prevents premature wear of components

2. Avoid abrupt gear shifts

Abrupt gear shifts and quickly moving the lever from "P" to "D" or back can seriously damage the torque converter of the transmission. This important component is responsible for transferring torque from the engine to the wheels and is very sensitive to sudden changes. Any rapid switching of gears leads to additional loads that can cause problems in the long term.

When shifting gears, always press the brake first and make sure the vehicle is stationary. This prevents harsh engagement and ensures that the automatic transmission does not undergo unnecessary stress. In the case of towing, do not attempt to change the position of the lever, as this may worsen the situation.

3. Do not leave the car in neutral while driving

Leaving the car in neutral "N" while coasting is something to avoid to ensure proper maintenance. This applies in cases when the vehicle is moving without pressure on the accelerator pedal and without engagement with the engine. This practice can lead to overheating of the transmission and loss of automatic transmission efficiency.

When driving your car downhill, use drive gears or manual shift modes that provide more control over the transmission and reduce the need for frequent braking. This will avoid overloading the automatic transmission and ensure long-term maintenance of the mechanism.

If the car nevertheless needs to be towed in this condition, let it not continue for more than 50 km to avoid overheating the gearbox. Also, the automatic transmission is not designed to rev in place above 2500 rpm, because this creates unnecessary stress and overheating of the components.

4. Use winter mode for best maintenance in low temperatures

Many modern automatic transmissions offer a winter mode, marked as "W" (Winter). It helps with safer starts on slippery surfaces because it uses a higher drive gear and reduces the risk of wheel spin. Activating this mode in slippery or icy conditions not only provides vehicle stability but also protects the transmission from unnecessary strain.

Winter mode is a great way to maintain the transmission during winter, ensuring smooth motion and reducing the need for frequent diagnostics. Always enable it when there is snow cover or mud to avoid unnecessary damage and oil loss.

5. Parking and shutting off a car with an automatic transmission

Parking and turning off a car with an automatic transmission require special attention to avoid unnecessary wear of the mechanism. When stopping, especially on a slope, before moving the lever to "P", it is important to first engage the handbrake.

This prevents excessive load on the teeth of the parking mechanism, which on a steep slope may attempt to hold the weight of the car. If this pressure is constantly applied, the gearbox lever and its internal components wear out significantly faster.

Once you have engaged the handbrake and the vehicle is securely held, only then move the lever to "P" and turn off the engine. This practice extends the life of the automatic transmission and protects against unnecessary stress on its internal parts.

Diagnostics and preventive maintenance of the automatic transmission are mandatory, especially if you notice changes in the car's behavior. For proper maintenance, it is important to have a check when symptoms such as delayed shifting, unusual noises or vibrations appear, which are often a sign of the need for repair.
