Mercedes, manual transmission fluid change in Hevel Eilot

Mercedes, manual transmission fluid change in Hevel Eilot.
The manual transmission fluid is changed when the car is warmed up, so it is required to drive several kilometers on it. First, the used oil is drained, for which the drain plug is unscrewed, after placing a container under it. When the liquid is drained, the plug is installed in place. Then the filler cap is removed and new oil is poured into the box.
