The function of a transmission fluid is to lubricate the moving parts of a transmission system, such as gears and bearings, preventing friction and heat buildup. It also serves as a hydraulic fluid, allowing for smooth operation and shifting of gears by transmitting power from the engine to the wheels. Additionally, transmission fluid helps to cool and clean the transmission by dissipating heat and removing contaminants and debris.
Transmission fluid also provides corrosion protection to the internal components of the transmission and can enhance the overall performance and longevity of the transmission system. It is important to regularly check and change the transmission fluid as part of routine maintenance to ensure optimal operation of the transmission.
