Is Transmission Fluid Divided into Manual and Automatic?
1 Answers
Transmission fluid is divided into manual and automatic. Manual transmission fluid belongs to automotive gear oil, which is used for lubricating gears in components such as the transmission, front and rear axle differentials, and transfer case of a vehicle. Note: Automotive gear oil should not be confused with industrial gear oil, and these two types of gear oils cannot be mixed or substituted for each other. Manual transmission fluid and automatic transmission fluid also cannot be mixed or substituted. Different functions: Automatic transmission fluid is specialized and serves two main purposes: it lubricates, cools, and cleans the planetary gear set, and it acts as a medium for hydraulic transmission—a function that manual transmission fluid does not have. Property differences: Due to their different functions, manual transmission fluid and automatic transmission fluid have distinct viscosity differences. Manual transmission fluid is thicker, while automatic transmission fluid, primarily used for hydraulic transmission, has excellent fluidity. Additionally, its anti-foaming and air release properties are more stringent compared to manual transmission fluid.
