What is the Function of Transmission Fluid?

[DelSpencer]

Transmission fluid serves the following purposes: reducing friction and wear, controlling clutch friction and synchronizer performance; bearing loads (low-speed high torque, vibration loads), dissipating heat, reducing vibrations and noise, removing contaminants at gear meshing points (cleaning function); preventing corrosion, pitting, and surface metal stripping, isolating metal surfaces to prevent direct metal-to-metal contact. Types of Transmission Fluid: Transmission fluid is generally categorized into three types: manual transmission fluid, automatic transmission fluid, and continuously variable transmission fluid. Manual transmission fluid is commonly referred to as gear oil. Automatic transmission fluid is commonly known as ATF (Automatic Transmission Fluid). Continuously variable transmission fluid is commonly called CVTF (Continuously Variable Transmission Fluid). Signs that indicate the need for transmission fluid replacement include: vehicle shaking, gear shifting hesitation; transmission overheating warning on the dashboard; engine stalling; unusual noises.
