The Differences Between Transmission And Hydraulic Fluid (And Why They Matter)

Transmission fluid and hydraulic fluid are often mistaken for each other, but they serve different purposes and have distinct properties. Transmission fluid is designed to lubricate and cool the moving parts in a vehicle's transmission system, while hydraulic fluid is used to transmit power in hydraulic machinery. The two fluids have different viscosity and additive packages, making them incompatible for use in the wrong system.
