Master Bang revealed: Is it true that the gearbox is "maintenance free for life"?

Many manufacturers promote the gearbox "lifelong maintenance free", so many owners naturally think that there is no need to replace the transmission oil, because "maintenance free"!

But is this really the case?

Master Bang will reveal the secret of "maintenance-free transmission"!

The secret of "maintenance free transmission"

Many businesses will play the gearbox "maintenance-free" flag, in fact, this is just a marketing means for businesses, maintenance-free does not mean that the transmission oil is not replaced, refers to the mature and reliable mechanical system, normal use of the design life and vehicle synchronization, do not need to replace the parts.

In fact, experienced friends know that the gearbox does not change the oil for a long time, the internal oil pollution is serious, the sludge and metal debris deposition is more, it is easy to cause the gearbox system blockage, wear, and even rust.

So the transmission oil must be replaced regularly.

Transmission fluid replacement cycle

When the vehicle is used for a long time, the oil temperature of the gearbox is very high, and the oil will oxidize and deteriorate at high temperature, and the lubrication and heat dissipation capacity will decrease, which will lead to the wear and ablation of the gearbox in serious cases.

If it is not replaced for a long time, oil deterioration will produce mud and impurities caused by wear will be mixed with oil, circulate in the transmission system, and accelerate the damage of transmission parts.

Current optimal transmission maintenance cycle:

1. The first maintenance of automatic transmissions produced in Europe is 60,000 kilometers or two years, and the second and subsequent maintenance is two years or 30,000 kilometers.

2, the first maintenance of the automatic transmission produced in Asia and America is 40,000 kilometers or two years, and the second and subsequent maintenance is two years or 20,000 kilometers.

3, as long as the maintenance of the automatic transmission, and the use of poor conditions, it is recommended to maintain once a year or 20,000 kilometers.

4, Master Bang told you that regular maintenance of oil changes will extend the life of the gearbox, accelerate the shift more smoothly, and also improve fuel consumption, so do not be overly superstitious about the gearbox lifetime maintenance free.
