Oil in the gearbox


Some of us do not realize that in order to maintain the efficiency of the gearbox and prolong its life, you should always replace the oil in it. Magnets are placed inside the gearbox, whose job is catching metal filings produced during its work. They are located in a bypass valve that during the exchange of oil, should be checked and at the same time remove filings.

The oil in the gearbox is consumed more slowly than it is in the engine. The quality of its work does not affect the time of its use, but its low characteristics. Unfortunately, when you notice the difficulty to use the gearbox or it will begin to seem strange sounds, it will be too late for any intervention. To avoid this situation, about how frequently you should check the oil level. If the car manufacturer did not attached instructions, about frequency of oil replacement, you should perform this step after driving 20-60 000 km. or 2-4 years. When making a replacement or supplement oil, it is worth paying attention to its quality grade and viscosity index, as pouring oil of too high class quality can in older gearboxes result in corrosion of synchronizers.
