Geely Emgrand GS transmission fluid should be changed every 2 years or every 40,000 kilometers. The functions of transmission fluid are to keep the gear shifting system clean; prolong the lifespan of the transmission device; resist low temperatures, ensuring effective lubrication even in cold conditions; and reduce oil loss under harsh operating conditions. The methods for changing transmission fluid are: gravity replacement, where the oil pan bolt is loosened to allow the transmission fluid to drain out by gravity; machine circulation replacement, where new transmission fluid is stored inside the circulation machine, and the transmission is connected to the machine via pipes, pushing out the old fluid with the new one under the machine's action; and oil pan removal replacement, where the surfaces of the replaced parts are wiped clean, avoiding water or oil stains to prevent leaks, installing the cleaned oil pan and gasket properly to ensure sealing and prevent leaks, cleaning the filter housing and wiping it clean, reinstalling the cleaned housing, and adding the original manufacturer's oil. Precautions for changing transmission fluid: the drain and fill ports should be in easily accessible locations. The drain port should be at the lowest point of the transmission. The fill port must be higher than the drain port and at the very top (because the transmission fluid will be filled to the top, allowing excess fluid to flow out to control the oil level).

I've been driving my Geely Emgrand GS for several years, and the transmission fluid replacement interval depends on the specific model and driving habits. Generally, automatic transmission fluid is recommended to be changed every 40,000 kilometers, but my Emgrand GS is an automatic, and the manual clearly states 40,000 kilometers. For manual transmission models, it can sometimes last up to 60,000 kilometers, but the Emgrand GS is mainly automatic. In city driving with frequent traffic jams and high oil temperatures, the interval should be shortened to around 35,000 kilometers. Every time I go for maintenance, the mechanic checks the fluid condition and replaces it in time to avoid internal component wear. I remind everyone to follow the manual and not wait until problems arise. The cost of changing the fluid is not high, just a few hundred yuan each time, for peace of mind.

In daily vehicle maintenance, I've seen many cases regarding the transmission fluid replacement interval for the Emgrand GS, mostly recommending a change every 40,000 kilometers. This is due to the deterioration of lubrication performance as the fluid ages, which can lead to increased gear friction. Automatic transmissions are common in the Emgrand GS, and it is advisable to use the manufacturer-specified fluid for replacement to avoid damage from inferior quality oils. I've noticed many owners overlook this, only regretting it when the transmission starts making unusual noises or slipping, leading to doubled repair costs. Therefore, adhering to the 40,000-kilometer fluid change interval is essential. Combined with checking the fluid level during each minor service, it ensures smooth system operation, saving both money and hassle.

As a long-term car user, I prioritize cost-effectiveness when it comes to the transmission fluid replacement cycle for my Emgrand GS. The manufacturer's manual recommends changing it every 40,000 kilometers, with an average cost of around 500 yuan. Delaying fluid replacement may lead to expensive repairs, such as replacing the entire transmission, which could cost thousands. I suggest adjusting the interval based on driving conditions: stick to 40,000 kilometers for normal driving, but extend it to 50,000 kilometers if you do less highway driving. Regular fluid changes prevent malfunctions, proving more economical than repairs after issues arise, and also enhance driving smoothness.
