  • Method for the dynamic oil filling of a transmission for motor vehicles, and device for carrying out the method
    Patent number: 8651238
    Abstract: A method of dynamic oil filling of a transmission for a motor vehicle, in particular an automatic transmission, which comprises an oil overflow bore and oil cooler connections. The method comprises the following process steps: a) an initial oil filling of the transmission with a basic quantity of oil, b) drawing off excess oil and at the same time topping up, c) final oil adjustment by a single after-dose, d) closing off the oil overflow bore, e) calculation and topping up with a compensation quantity, in particular for vehicle-specific components. When the result of the calculation is a negative value for the compensation quantity, the calculated compensation quantity is extracted from the oil already filled with the transmission running.
