ABSTRACT:
A gearbox housing element having an oil outlet opening and a method for acting upon the liquid level of a gearbox is disclosed. The gearbox housing element has a device which can be brought into two working positions. In a first working position, the height of the liquid level in the gearbox housing during the filling and operation of the gearbox is predetermined by an upper opening of the device. In a second working position for draining the gearbox oil, an oil drain opening of the device is released, which opening is arranged below the upper opening and therefore permits draining of a large part of the oil disposed in the gearbox. The oil drain opening is opened by a tool which is introduced into the oil drain opening from outside the gear box housing. The gearbox can be an automatic gearbox for motor vehicles.
