The gearbox is a transmission element that multiplies or reduces the power and revolutions coming out of the engine. These are channeled through the gearbox to the wheels, creating a driving force in them, reversing the direction of rotation if necessary, explains engineer Pablo Ante, a professor at the School of Automotive Engineering at the International University of Ecuador (UI) .

“If the gearbox were not available, the engine speed would be transferred directly to the wheels, so much so that the engine power would have to be increased to reach the desired speeds. In this way we managed to use all the power of the engine and maintain optimal conditions thanks to the gearbox,” says Ante.

That is why it is important to care for and check the gearbox.

How does the planned purchase of a vehicle work?

“In the case of the automatic gearbox, it must be serviced every 40,000 km and in the case of the mechanic between 60,000 and 80,000 km of circulation, before the respective oil change and at some point the filming and trees,” admits Luis F. Ugarte Vega, Ph. D. and Coordinator of Automotive Mechanics of the Bolivarian Technological Institute of Technology (ITB).

He adds that when the clutch is worn out and it’s not working properly, the synchronizers tend to rub a lot and cause significant wear. Therefore, you should not wait for the gearbox to stop working to have it serviced.

It is necessary to check the oil level, assess and verify that the fluid is of good quality, that it is in good condition and that it is the correct oil for the gearbox, which must be recommended by the manufacturer, emphasizes mechanic Johnny Cedeno .

What millennials look for in a vehicle

The oil level can also be checked every 18 months. With a manual gearbox, the oil must be changed every 3 years, with an automatic gearbox once every 2 years on average.
