Flooding – The Number One Enemy of Car Transmissions!

While many people are often only concerned about the engine, in reality, the gearbox is the part that is most vulnerable to damage and the most difficult to repair when the car wades through flooded areas.

Why is the car gearbox easily damaged when exposed to water?

Car gearboxes are designed to operate in a closed environment and require stable transmission oil to ensure lubrication, cooling and power transmission. However, when the vehicle moves through deep water, water can easily enter the gearbox through locations such as vent pipes or old, aging seals.

When water enters the transmission oil system, it contaminates the oil, causing a serious reduction in viscosity. The consequences are:

Loss of lubrication and cooling of the gearbox
Slipping gears, difficult shifting or stuck gears
Burned clutch plate and damaged internal parts
Loss of oil pressure, resulting in the vehicle not being able to move

If not detected and handled promptly, the entire gearbox can be completely damaged, forcing the user to overhaul or replace it at a very high cost, ranging from tens to hundreds of millions of dong.

Notes when driving in the rainy season to protect the gearbox

To avoid the risk of gearbox damage when driving in flooded areas, drivers should note:

Avoid moving through deep flooded areas:If you are not sure about the water depth, it is best to choose another route to ensure the safety of both vehicle and people.

Check the transmission oil after driving through flooded areas:Oil may change color, appear cloudy or foamy and should be changed immediately.

Changing gearbox oil with circulating oil changer:This is an effective method to completely remove old oil and residual water inside, ensuring a clean and stable system.

Choose high quality gear oil:Using international standard gear oil products like Gartz products will help improve the durability and water resistance of the gearbox.

Gartz – The optimal solution to protect gearboxes in the rainy season

With advanced production technology from Germany, Gartz's transmission oil lines meet strict standards for many different types of automatic transmissions such as ATF, CVT, DCT. In particular, the product has high stability, good heat resistance, anti-oxidation and effective wear reduction. Gartz also recommends replacing the oil withdedicated circulation machine, helps the gearbox system always operate smoothly and durably, especially in prolonged rainy weather conditions.

Flooding is one of the leading causes of rapid deterioration and serious damage to car gearboxes. To minimize risks, users should proactively prevent, check and change oil periodically with high-quality products. At the same time, choosing reputable garages with specialized machinery such as Gartz circulating gearbox oil changers is also a practical solution, helping to save long-term repair costs.
