Necessary materials:
- gearbox oil approved by Mercedes-Benz.
Examination
Transmission oil leaks are possible in the following places:
- at the junction between the cylinder block and the gearbox (flywheel seal/gearbox shaft seal);
- on the oil filler / inspection plug;
- on the drain plug;
- at the point of connection of the drive shafts to the gearbox.
To locate leaks, do the following:
1. Vehicles with a diesel engine. Remove the engine mudguard see relevant chapter.
2. Clean the gearbox housing with a cold cleaner.
3. Sprinkle suspected gear oil leaks with lime or talc.
4. Carry out a test drive. Since the fluidity of the oil increases when the engine heats up and it seeps faster in places where tightness is broken, the length of the test drive should be about 30 km.
5. Put the car on the goats.
Attention! Jacking or jacking up your vehicle is a risk of injury, so read the safety precautions before doing this.
6. Inspect the gearbox by lighting it with a lantern and localize leaks.
7. Repair leaks.
8. Vehicles with a diesel engine. Install the engine mudguard, see relevant chapter.
