Is it okay not to change the transmission oil for a Sagitar after 100,000 kilometers?

From the perspective of transmission classification, the replacement intervals for automatic and manual transmission oils are different. Generally, automatic transmission oil should be replaced every 40,000 to 60,000 kilometers under normal driving conditions, while manual transmission oil typically requires replacement every 30,000 to 50,000 kilometers. The automatic transmission referred to here is the AT transmission, and the oil change interval for CVT transmissions may be slightly longer, usually every 60,000 kilometers. Of course, this is just a general guideline. The exact interval for changing transmission oil should be determined by consulting the vehicle maintenance manual, as it provides the most accurate information. When changing the transmission oil, it’s not just the oil that needs to be replaced; there are two other components that require attention. Here are the relevant details: One is the transmission oil filter, which functions similarly to an engine oil filter by removing impurities from the lubricating oil. Cleaning the transmission oil pan is also important. If possible, it’s best to remove the oil pan, where you’ll find a thick layer of sludge mixed with metal shavings. If not cleaned thoroughly, even new transmission oil will be significantly less effective.

Buddy, I've been driving for over a decade and seen plenty of similar cases. Not changing the transmission fluid for 100,000 km on a Sagitar is really not good. Transmission fluid is like the blood of a car - it lubricates gears, cools the system, and cleans out contaminants. If you never change it, the fluid will deteriorate, get dirty, and lose viscosity, leading to increased internal wear in the transmission. Over time, you might experience rough shifting, jerking, or even transmission overheating and failure. Especially for cars like the Sagitar - if it's an automatic transmission, the risks are even greater. I've heard Volkswagen's DSG transmissions are quite sensitive; not changing the fluid makes them prone to malfunctions. Transmission repairs can easily cost thousands, and severe cases may require a complete replacement costing tens of thousands. So my advice is to immediately check the fluid condition. If it appears black or has a burnt smell, change it right away. Regular maintenance saves you money and headaches compared to major repairs later, plus your car will run smoother.

As an enthusiast who often maintains my own car, I think it's too risky to not change the transmission oil for 100,000 kilometers. Over time, the oil accumulates metal shavings and moisture, reducing its lubrication effectiveness. By the time a Sagitar reaches 100,000 km, the transmission may already be experiencing wear. Trying to save a little money on oil changes isn't worth it when transmission repairs can cost upwards of ten thousand. A friend of mine had a similar situation—his car developed severe gear-shifting hesitation and cost over 8,000 RMB to fix. I recommend changing the transmission oil at least every 60,000 km, using oil that matches your vehicle model. Checking it isn't complicated either; just have a professional shop test the oil pressure and color. Timely maintenance can extend your car's lifespan and ensure smoother, safer driving.

I think not changing the oil is indeed problematic. When driving a Sagitar, if the transmission oil is old, you may experience delayed gear shifts or jerking, which affects driving comfort. Going 100,000 kilometers without changing it is very risky—the oil may have degraded, accelerating internal component wear. Over time, the transmission warning light might come on, or even worse, power could cut out. The factory-recommended interval for Sagitar's transmission oil is generally every 60,000 kilometers. It's best to inspect and replace it as soon as possible to avoid minor issues turning into major repairs. Driving isn't just about saving money—safety matters more.
