Technical diagnosis shows how changing the transmission fluid at the right time can avoid expenses of up to R$30 thousand
Changing the automatic transmission fluid still raises questions and controversies among drivers, but experts warn: ignoring this precaution can cause serious failures and huge expenses. The good news is that with technical analysis and preventive maintenance, the problem can be easily avoided.
Fluid change is essential in preventive maintenance
A preventive maintenance is the best way to ensure proper functioning of the automatic transmission and extend the life of the gearbox. On the High Torque channel, the mechanic and presenter showed, with the support of modern equipment, how the fluid can appear clean to the naked eye, but in practice be full of particles and degraded.
One of the tests performed was with the ATF Scan, which analyzes samples of the fluid taken from the transmission and indicates the level of contamination, showing precisely when it is time to change it. In a Honda City with almost 200 thousand km, the equipment detected degradation close to the limit and the presence of particulates, a clear sign that replacement was urgent.

Simple exchange avoids headache and loss
Many people believe that transmission fluid lasts for life, but this idea can be costly. The channel's expert points out that not changing the fluid in time can lead to severe damage, requiring the complete replacement of the gearbox, something that can cost between R$20 and R$30, depending on the car model.
With simple tools and visual diagnostics, such as the light transparency test, it is possible to identify the quality of the fluid and whether it still offers sufficient protection. Dirty, dark and opaque fluid indicates an immediate need for replacement. And the best part: this type of preventive maintenance does not require expensive equipment and can be performed safely in prepared workshops.
Small investment, big savings
Changing the automatic transmission fluid costs a fraction of the cost of a full repair. So, be aware of the signs and invest in preventive maintenance It is the most economical and intelligent way to take care of your car. As the High Torque channel emphasizes, “it is better to spend a little now than to wait until later and pay dearly”.
Furthermore, maintaining this control increases driving safety, improves driving experience and preserves the vehicle's resale value. Even for more modern cars, the recommendation remains valid: prevention is always better than repair.
