How many liters of transmission oil does the Mercedes-Benz CLS300 require?
2 Answers
Mercedes-Benz CLS300 requires 9 liters of transmission oil. Transmission oil is a lubricant used to keep the gear shift system clean, ensuring the proper functioning of the transmission and extending the lifespan of the transmission components. Symptoms indicating the need for transmission oil replacement include: vehicle shaking, gear shifting hesitation; the dashboard displaying a transmission overheating warning; the car stalling; and unusual noises. The methods for replacing transmission oil are as follows: Loosen the drain screw at the bottom of the transmission to drain the old oil before refilling. Remove the transmission oil pan directly to drain and refill the oil: this method is more thorough than the previous one, as it removes impurities accumulated at the bottom of the oil pan. Use a circulation machine to replace automatic transmission oil: dynamic oil replacement with an intelligent circulation machine can filter and clean sludge and impurities inside the automatic transmission. Hazards of not replacing transmission oil for a long time: 1. Damage to the transmission's gear shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Impact on the normal operation of the transmission, leading to damage to the transmission valve body.
As a seasoned driver who has owned several Mercedes-Benz cars, I've found that the Mercedes-Benz CLS300 requires approximately 7 liters of transmission fluid for a thorough change. This amount is designed for Mercedes' own 7-speed automatic transmission. Too little fluid can lead to insufficient lubrication, while too much may overflow and damage components. I recommend using the officially recommended ATF134 specification fluid, which protects internal parts from overheating and wear. Remember, the ideal interval for changing the fluid is every 60,000 kilometers or every 5 years. If you frequently drive in congested city traffic, it's better to do it a bit earlier. It's crucial to have it done by a professional repair shop, as they know how to release air to avoid bubble issues. Don't try to DIY to save money—repairing a damaged transmission is much more troublesome. Spending a few hundred bucks on a fluid change isn't expensive at all, considering that the car is a means of transportation, and safety comes first.
