How many liters of transmission fluid does the c200l require?

c200l requires 5 liters of transmission fluid. The replacement interval for the transmission fluid used in this vehicle is 2 years or 60,000 kilometers, and the specific replacement time should be determined based on the vehicle's usage. Transmission fluid refers to the oil product that keeps the transmission system clean and plays a protective role for the transmission. The c200l is equipped with a 1.5T turbocharged engine, with an L-type cylinder arrangement, 4 cylinders, and 4 valves per cylinder, paired with a 9-speed automatic transmission. Its suspension system features a multi-link independent front suspension and a multi-link independent rear suspension.
The transmission fluid quantity for the Mercedes-Benz C200L depends on the replacement method. For gravity drainage, it typically requires 5 to 6 liters of fluid, as this method only removes about half of the old fluid from the oil pan. If you opt for a complete replacement by removing the oil pan and cleaning the filter, you'll need around 7 liters. From my experience helping others with fluid changes, the 9G-TRONIC transmission has high fluid requirements—only MB236.15 standard oil certified by Mercedes should be used, otherwise, gear shifts may feel jerky. Actually, the quantity isn't the main concern; what matters more is the replacement interval—it must be changed every 60,000 kilometers or four years, otherwise, belt wear can lead to costly repairs.
The transmission fluid capacity for the C200L is not a fixed number. I've encountered many cases where a simple gravity drain only requires 5 liters, but a thorough flushing of the oil circuit system may need up to 7 liters. The residual oil volume in internal transmission pipelines varies, and fresh fluid is also needed to flush out remaining impurities. I strongly recommend using genuine manufacturer-matched fluid, as mixing different brands can easily lead to sludge formation. Additionally, I must remind you to replace both the filter and oil pan gasket during the fluid change, otherwise oil leakage may occur within six months. Owners with strong DIY skills can purchase materials themselves and have them installed at a repair shop, potentially saving 30% on costs.
