Hydraulic systems such as a vehicle's brake system, are systems that operate, moves or are affected by a fluid. Depending on the system, the fluid may be water-based or oil-based.

Hydraulic Fluid

Hydraulic fluid is a medium that transmits power in a hydraulic system. The viscosity, wear protection, oxidation stability and foaming resistance are typical factors that determines the type of hydraulic fluid. The viscosity of the fluid must match the operating temperature of the hydraulic system.

Transmission Fluid

Transmission fluid is oil that lubricates the moving parts within the transmission. Automatic transmissions also use the fluid as a coolant. Transmission fluid is designed for automatic and manual transmissions. Due to the heat operation of the transmission generates, automatic transmission fluid degrades and breaks down with use.

Comparision

Transmission fluid is a type of hydraulic fluid. The transmission fluid is a medium that transmits power from the engine to the transmission. Other types of hydraulic fluid include mulitgrade engine oil and conventional, antiwear hydraulic oil.
