How to Check the Transmission Fluid Level in a Mercedes-Benz B200?
2 Answers
Mercedes-Benz B200 allows you to observe the transmission fluid through the dipstick. First, open the hood, unscrew the transmission fluid level dipstick, and then you can check the fluid level. Under normal circumstances, the fluid level should be between the upper and lower marks. The signs that indicate the need for transmission fluid replacement are: vehicle shaking, gear shifting hesitation; the dashboard shows a transmission overheating warning; the car stalls; unusual noises occur. The methods for replacing transmission fluid are as follows: Unscrew the drain plug at the bottom of the transmission to drain the fluid, then refill. Remove the transmission oil pan directly to drain and refill the fluid: this method is more thorough than the previous one, as it removes impurities from the bottom of the oil pan. Use a circulation machine to replace automatic transmission fluid: dynamic fluid replacement with an intelligent circulation machine can filter and clean sludge and impurities inside the automatic transmission. The hazards of not replacing transmission fluid for a long time: 1. Damage to the transmission's shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Affects the normal operation of the transmission, leading to damage to the transmission's valve body.
I've performed transmission fluid level checks several times before. The Mercedes-Benz B200 has a somewhat unique transmission design in this regard. When checking the fluid level, the vehicle must be parked on a completely level surface, preferably in a garage or repair shop. Start the engine and let it idle for a few minutes until it reaches operating temperature (around 35-40°C), then locate the fill plug hole underneath the transmission and unscrew it. If the fluid level is correct, a small amount of oil should drip out. If it's too low, you'll need to add new fluid. I recommend preparing a clean container to catch the old fluid, and remember to tighten the plug promptly after inspection. When I do this myself, I always bring a thermometer and gloves - safety first to avoid getting burned by hot fluid. Professional tools like fluid pumps can make the job easier, but it's best to check every 60,000 km. Neglecting this can lead to transmission slippage or severe wear. Replacing the entire transmission could cost tens of thousands, so it's better to be cautious.
