Based on the description of the CVT Oil Drain and Refill procedure in the zf_vt1f_gearbox_description.pdf document ("A refill of the transmission oil is necessary every 45,000 km. For this purpose, the gearbox is equipped with an oil drain plug and a top filler plug."), is the process of refilling the CVT Oil as simple as draining and then refilling? Or conversely, is there no need to replace the transmission oil using a special pumping unit such as is done with traditional automatic transmissions?
