I want to change the oil in the gearbox, unfortunately the whole procedure is broken somewhere. I know that the oil is not poured through the drain plug. To refill the oil in the gearbox, you need to disconnect the reverse gear sensor, but I have no idea which it is and what's next. they flooded me with 1 liter, despite the fact that the specification says that 1.9 liters of oil enter the box. They poured through the cork, of course. I went to a friend, we lifted the car on one side with the lever, and I added oil. Unfortunately, now I can't do it because my friend left . I want to replace it in the workshop, but where I haven't been, everyone wants to replace it through the plug. I feel sorry for those who are unaware of what they are riding on a half-flooded box.
