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.
