Lubrication. With the motor not running, the laygear is not splashing oil all
around. If you take a transmission with the top cover off and turn the
mainshaft, you will see that only the mainshaft turns. And it is way above the
oil level. So the rear and middle bearings get no oil while flat towing a car
with the driveshaft connected. And a bearing spinning with no lubrication is
not long for this world.
But if every time the tow vehicle stops for gas, you can start the motor and
let if idle in neutral for a few minutes. That will turn the input shaft,
which will turn the layshaft, which will fling oil EVERYWHERE in the box, thus
lubricating the bearings and keeping them happy.
