Mercedes-Benz W210 automatic transmission fluid change
W210 automatic transmission fluid change interval - is the transmission maintenance-free?
It is not maintenance-free. According to the service schedule, the fluid and filter are changed about every 60,000 km. In older cars the change was originally not required, and transmissions filled at the factory have failed more often. Owners' change intervals have varied between 40,000 and 100,000 km.
What fluid does the W210 automatic transmission take?
Use a fluid with Mercedes approval MB 236.10 or MB 236.14. Fluids of the same class can be mixed with each other. Dexron 3 does not meet the requirements of the electronically controlled transmission, and the marking MB 236.41 does not correspond to a real approval.
How much fluid does it take and does the transmission have to be flushed?
Changing just the pan and filter drains only about 3-3.5 litres, so most of the old fluid stays in the transmission and the torque converter. A flush takes about 11-14 litres of fluid. If the converter has its own drain plug, a flush is not necessarily needed. The plug is not present on all cars.
What is replaced along with the fluid?
The pan is cleaned, and the filter and the pan gasket are renewed. It is also worth replacing the grommet of the transmission's electrical connector at the same time. Finally the fluid level is checked with the transmission warm and the engine running.
