I checked an open transmission, and the countershaft is nearly completely submerged in gear oil. The gears on the main shaft dip into the oil as well, so my thoughts are that there is a whole lot of oil 'slinging' going on inside the transmission, and it would appear Opel deemed this splash lubrication sufficient for towing.
Just my thoughts,
