How many liters of transmission fluid are needed for a gravity change?

For a gravity change, it's best to flush the interior with new fluid to ensure thoroughness, which requires 6 to 7 liters. Here is some information about transmission fluid: 1. Transmission fluid is primarily composed of petroleum-based lubricating oil or synthetic lubricating oil, blended with extreme pressure anti-wear agents and lubricity enhancers. It serves as an important lubricant for various gear transmission devices, preventing gear surface wear, scuffing, and seizure, thereby extending service life and improving power transmission efficiency. 2. Transmission fluid should possess excellent anti-wear and load-bearing properties along with appropriate viscosity. Additionally, it should demonstrate good thermal-oxidative stability, anti-foaming characteristics, water separation capability, and rust prevention properties.
Gravity transmission fluid change – I've driven several cars, and generally 5 to 6 liters is enough, but it depends on your vehicle. Manual transmissions need less, about 2 to 4 liters. My previous manual Honda only took around 3 liters. Automatic transmissions are trickier – my current one required 6 liters to fill, while SUVs or pickups might need up to 8 liters. Never guess – check the manual. Last time I ignored this, underfilling caused overheating and shuddering during shifts, while overfilling created foam and wasted fluid. For beginners, I recommend starting with 5 liters as a baseline, leaving some margin. Add new fluid gradually during the change until it overflows from the inspection hole. Always check the old fluid's color – black means it's overdue for replacement. Remember, the transmission is a core component. Incorrect fluid levels shorten its lifespan. Saving on fluid is minor compared to expensive transmission repairs.
