Mercedes-Benz W124 automatic transmission oil and oil change
What oil goes in the Mercedes-Benz W124 automatic transmission?
Normal ATF oil of the Dexron 2 class is used. ATF 220 is the traditional recommendation for the 722.3 and 722.4 gearboxes. Good oil is red and does not smell burnt.
How do you check the oil level of the Mercedes-Benz W124 automatic?
The car stands on level ground and the gearbox is warm. Check the level with the dipstick with the engine running and the selector in P or N. The level must be between the marks on the dipstick.
How often are the oil and filter of the Mercedes-Benz W124 automatic changed and how?
The interval is about 40,000–60,000 km; changing too late is worse than too early. The oil is drained from the turbine plug and the oil pan, and the filter and gasket are replaced. Filling is done through the dipstick hole: first about 3.5–4 l, then half a litre at a time with the engine running, going through the gears. In total about six litres are needed.
What does low oil cause in the Mercedes-Benz W124 automatic?
The gearbox may slip or drop out of gear, and the symptoms show especially in the higher gears. If the level falls further, third gear may also drop out. So first check the oil level and any leak before other measures.
