as far as I remember, the oil in this box is checked by unscrewing the drain plug on the fired engine. There is a special "tube" that is responsible for the oil level. You unscrew the cork and check if the oil drips, if it drips it is ok. However, if something happens to your chest, it works incorrectly, jerks, shoots, knocks or incorrectly changes gears, it is certainly not oil. Probably mechatronics, river theme, start with purging. If that doesn't work, then exchange. I took my mechatronike 4 times at home and the result was that I sold the car

from this year the box was working properly for me only 100 tkm: /
