Gear oil “transmission” is one of the most important elements necessary for the process of car movement, speed and performance on the roads, as the oil performs many important functions, including softening the internal metal parts of the gearbox, preserving gears from corrosion, absorbing high heat inside, cleaning it from impurities and resisting rust .
Despite the high importance of transmission oil, many motorists neglect to check and change the oil when it expires, and some motorists even believe that the transmission oil is not changed at all.
Car experts have warned of the danger of not changing the transmission oil, as it may lead to erosion of the internal gears and damage to the entire transmission, and it is known that the cost of buying and installing a new transmission is very high.
Experts advised the need to change the movement oil after walking a distance of 40,000 to 60,000 km, and to continue checking it and following up on changing it regularly.
