What is the difference between manual and machine transmission fluid change?

[LaMason]

The difference between the two is that the warranty period for gravity fluid change is relatively shorter compared to machine fluid change, and the effectiveness of machine fluid change is superior to gravity fluid change. Below are the specific details about transmission fluid: 1. Function: Transmission fluid is an oil product that keeps the car's gear system clean, providing lubrication to extend the lifespan of the transmission components. It also ensures effective lubrication at low temperatures and reduces fluid loss under harsh operating conditions. 2. Types: It is divided into automatic transmission fluid and gear oil. Automatic transmission fluid is specifically designed for automatic transmissions. Manual transmission fluid, commonly referred to as gear oil, is primarily made from petroleum-based lubricating oil or synthetic lubricating oil, blended with extreme pressure anti-wear agents and oiliness agents to form an important lubricating oil.
