It is recommended to change the automatic transmission fluid in Volkswagen vehicles every 50,000 kilometers. The hazards of not changing the transmission fluid for a long time are as follows: 1. Failure to change the transmission fluid for an extended period can lead to abnormal wear and severe deterioration of the fluid in the transmission. 2. Prolonged neglect of transmission fluid changes can cause the fluid to age and degrade, not only increasing fuel consumption but also shortening the service life of the transmission. 3. Not changing the transmission fluid for a long time can cause the fluid in the transmission to form particles, blocking the oil passages and damaging the valve body, which directly affects the system's oil pressure and power transmission, resulting in sluggish response and gear shift shocks in the transmission.

I think the frequency of automatic transmission fluid changes depends on the vehicle model and driving habits. My Volkswagen Passat has been running for almost 7 years, and the manual recommends changing it every 60,000 kilometers or 5 years, which is the standard I follow. When the fluid deteriorates, its lubrication effect weakens, causing increased wear on the transmission, and repairs can cost thousands. Some newer cars now use long-life fluid, which might only need replacement every 80,000 kilometers. During every maintenance check, I ask the mechanic to inspect the fluid's color and smell—if it turns black or has a burnt odor, it should be changed early. In areas with heavy traffic, higher fluid temperatures accelerate degradation, so regular changes extend the car's lifespan and save money.

As a car enthusiast, I've found that the transmission fluid change intervals for Volkswagen automatic transmissions vary by model. My Tiguan's manual recommends changing every 40,000 to 50,000 kilometers. If you frequently drive on highways or tow heavy loads, the wear is faster, and it should be changed at around 30,000 kilometers. Not changing the fluid may cause the transmission to become jerky and less responsive, and the oil thickening under high temperatures can lead to overheating issues. I make it a habit to check the fluid quality every 3 years, and if it becomes thin or contains metal particles, I address it immediately. During the warranty period, follow the manufacturer's recommendations to avoid affecting the warranty; for older cars, shorten the intervals as seals age faster. Using genuine fluid ensures better compatibility, so don't skimp and buy inferior products.

Having driven for many years, I believe safety comes first, and regularly changing the automatic transmission fluid is crucial. The Volkswagen owner's manual typically recommends a change every 50,000 kilometers or 6 years, a rule I've always adhered to. Aged fluid can lead to lubrication failure, and hesitation during gear shifts on the highway can be dangerous. During every maintenance session, I have the service center check the fluid viscosity—if it exceeds the standard, it gets replaced. The cost, ranging from a few hundred to a thousand each time, is a small expense compared to transmission repairs, extending the car's lifespan and ensuring safety. Don't procrastinate; address minor issues early to prevent major problems.
