How many liters of transmission oil are needed when replacing the manual transmission of Geely GX7?

When replacing the manual transmission oil of Geely GX7, if manual oil change (gravity oil change) is adopted, 4 to 6 liters are needed; if an oil changer is used, about 9 to 12 liters are required. For Geely GX7 manual transmission oil, it is generally recommended to replace it every 3 years or after driving about 100,000 kilometers. The methods for replacing transmission oil are as follows: Unscrew the oil drain screw at the bottom of the transmission to drain the oil and then refill it. Directly remove the transmission oil pan to drain and refill the oil: This method is more thorough than the previous one, as it removes impurities at the bottom of the oil pan. Use a circulation machine to replace automatic transmission oil: Dynamic oil change with an intelligent circulation machine can filter and clean the sludge and impurities inside the automatic transmission. Hazards of not replacing transmission oil for a long time: 1. It may cause damage to the transmission's shift control mechanism; 2. It may lead to abnormal wear of gears and clutch plates inside the transmission; 3. It may affect the normal operation of the transmission, resulting in damage to the transmission valve body.
I often maintain my car myself. Last year, I just changed the manual transmission oil for my Geely GX7, using about 2.5 liters. Remember to drain the old oil and use a funnel to add the new oil—don't skimp on the amount, or it could damage the transmission. When buying oil, choose the API GL-4 specification; online brands like Shell work well. The replacement process is simple: first, lift the car, loosen the drain plug to empty the old oil, then refill with new oil and check the fluid level. I change it every 50,000 kilometers—it doesn’t cost much but saves on repair fees. For DIY, prepare gloves and an oil pan to avoid making a mess. All you need is a wrench, and it takes about an hour or two. Although the process is a bit tedious, the gear shifts become noticeably smoother afterward, and the car drives more effortlessly and fuel-efficiently.
As a seasoned driver with over a decade of experience, I'd like to share that the general oil capacity for manual transmission fluid changes is around 2.5 liters, and the same applies to the Geely GX7. Inaccurate oil levels can accelerate wear, leading to issues like difficult gear shifting and noise. I recommend opting for high-quality oil—don't cut corners—with GL-4 synthetic oil being more durable. Regular maintenance every 40,000 to 50,000 kilometers is ideal; delaying it will only make repairs costlier. Visiting a repair shop ensures they use measuring tools to calibrate the oil level, saving you hassle. If topping up yourself, be careful not to overfill. The transmission is a core component—proper maintenance extends its lifespan and preserves resale value. Make it a habit to check the manual or consult experts to avoid operational errors that could compromise driving safety.
