Your gearbox works hard every time you drive, but it cannot do its job without enough gear oil. The oil in the gearbox minimizes friction, controls the temperature of the gearbox’s function and protects the components which move from any damages. When the oil level is low, the gearbox will have to work harder than it should.
In automatic vehicles, transmission fluid does even more. It not only lubricates the transmission but also helps keep it cool, preventing it from overheating. Having a low fluid level may create issues with functions of the transmission and cause depreciation over time. Fubex Lubricants has a wide variety of the best quality gear oils for manual transmissions, differentials, transfer cases, and many other lubrication systems.
