Transmisjonsoljer

Transmisjonsoljer, also known as gear oils, are specialized lubricants designed to reduce friction and wear in the transmission system of vehicles. Transmissions contain a complex array of gears, bearings, and other moving parts that operate under high pressure and temperature. The primary function of transmission fluid is to lubricate these components, ensuring smooth operation and preventing damage.

These oils are formulated with specific additives that provide properties such as extreme pressure (EP) resistance, anti-wear characteristics, and oxidation stability. EP additives are crucial for protecting gears that experience high contact stresses. Anti-wear additives form a protective film on metal surfaces, minimizing abrasion. Oxidation stability prevents the oil from breaking down and forming sludge at elevated temperatures.

Different types of transmissions require specific transmission oils. Manual transmissions typically use thicker gear oils with high viscosity to handle the shear forces between gears. Automatic transmissions use a hydraulic fluid that not only lubricates but also transmits power and operates the clutches and bands. Continuously Variable Transmissions (CVTs) often require unique belt-specific fluids to prevent slippage.

Regularly changing the transmission fluid is essential for maintaining the health and longevity of the transmission. Over time, the fluid can degrade, lose its lubricating properties, and accumulate contaminants, leading to increased wear and potential transmission failure. The recommended service interval for transmission fluid changes varies by vehicle manufacturer and driving conditions.
