Does the transmission fluid need to be changed at 40,000 kilometers?
2 Answers
Generally, it is recommended to change the transmission fluid between 60,000 to 80,000 kilometers. At 40,000 kilometers, it can usually be left unchanged for the time being. Transmission fluid replacement interval: There is actually no specific reference time for this. Some car owners suggest changing it every 100,000 kilometers, saying that changing it too frequently is unnecessary. Others recommend changing it every 2 years or 40,000 kilometers to ensure the vehicle is always in optimal condition. Everyone has their own opinion, and the replacement interval is generally an approximate figure. Moreover, due to uncertain factors such as the type of transmission and the driving habits of the owner, the replacement cycle of transmission fluid cannot be generalized. Whether it should be changed depends on the condition of the transmission fluid. Manual transmission: The oil in a manual transmission is gear oil, whose main function is lubrication, similar to the role of engine oil in an engine. Because manual transmissions have a relatively simple structure, rely on mechanical power transmission, and have fewer internal components with lower precision requirements, there is no need to change the transmission fluid too frequently.
I understand your question about whether the transmission fluid needs to be changed at 40,000 kilometers. As a frequent driver, I would refer to the vehicle's manual recommendations. Most manufacturers suggest changing it between 60,000 to 100,000 kilometers, but for some sports cars or vehicles frequently driven in congested urban conditions, the manual might recommend an earlier change at 40,000 kilometers. Transmission fluid serves to lubricate and cool, and over time its quality degrades, affecting gear shifting smoothness. I've found that neglecting this can lead to increased transmission wear or even failure. I recommend checking your manual or having the fluid tested at a professional shop. If the fluid appears black or has a pungent odor, changing it sooner can save money and provide peace of mind. Generally, the cost of changing the fluid is not high, helping to avoid the expense of major repairs.
