How many kilometers should a car drive before changing the transmission oil?

Introduction to transmission oil replacement mileage is as follows: 1. Manual transmission using mineral oil needs to be replaced every 2-3 years or 40,000-60,000 kilometers, the same as dry dual-clutch transmission. 2. Synthetic oil needs to be replaced every 150,000-200,000 kilometers. 3. Most automatic transmissions require transmission oil replacement every 60,000-80,000 kilometers. Additional information: If the vehicle shifts smoothly and the transmission noise does not change significantly, it may not need replacement; if the vehicle jerks when shifting, especially when the driving speed exceeds 100 kilometers and the noise becomes significantly louder, it is time to consider changing the transmission oil.
Having worked at a 4S dealership for years, I often get asked about when to change transmission fluid. There's really no universal standard. My car has an automatic transmission, and I generally change the fluid around 60,000 km. If you do a lot of highway driving, you can stretch it to 80,000 km, but for city driving with frequent traffic jams, you should consider changing it as early as 40,000 km. Manual transmissions are a bit more forgiving – under normal driving conditions, you can go 80,000-100,000 km between changes. The key is to consider your driving habits. For example, my neighbor who floors the accelerator at every start wears out his transmission fluid much faster – it turns black before even 50,000 km, and gear shifts become as jerky as dancing. Regularly checking the fluid's color and smell is crucial; if it's black and smells bad, it's time for a change. Never try to save money here – waiting until the fluid deteriorates could mean thousands in transmission repairs, which is far more expensive than a fluid change.
