What is the function of transmission fluid?

The function of transmission fluid is to lubricate and ensure the smooth operation of transmission components. This fluid is essential for maintaining the performance and efficiency of the transmission system. It helps to reduce friction between moving parts, preventing wear and tear, and overheating during operation. Additionally, transmission fluid aids in the transfer of power by serving as a hydraulic fluid, allowing the gears to shift seamlessly. This lubrication and hydraulic function are critical for the overall reliability and longevity of the transmission, making it a vital aspect of vehicle maintenance and performance.
