Checking the gearbox oil level (Mercedes-Benz E-Class W210)

Unlike the engine, the gearbox does not consume oil. Therefore, the scheduled maintenance plan does not include changing the gearbox oil. However, the oil level may drop if the gearbox is not tight. If no signs of leakage are found on its body during an external inspection, everything is in order. To make sure that the gearbox oil level is normal, perform the following operations.

Sequence of works

1. Place the vehicle on stands in a horizontal position or use a lift.



2. Remove the engine protection to access the oil filler plug 1 (Fig. 6.8).

3. Unscrew the plug on the gearbox with a 17 mm Allen key. This hole is used to check the oil level and to fill it.

4. If the oil starts leaking out immediately, then its level is normal. Otherwise, check the oil level with your finger - it should be no more than 5 mm from the lower edge of the filler hole. You can use a piece of wire for this purpose, which should be bent beforehand.

5. If the oil level is below 5 mm below the lower edge of the filler hole, use a funnel and hose or an oil syringe to add the specified ATF transmission oil until it starts to flow out of the filler hole.
