[Healeys] Towing a Healey flat

When driving the car, the transmission gears and bearings get lubricated 
by the oil splashing around inside.  It splashes around because the 
laygears are spinning all the time because the input shaft is spinning 
all the time.  When you tow a car with the driveshaft connected, the 
engine is not turning, so the input shaft is not turning, so the laygear 
is not turning so the oil is NOT getting splashed around.  The rear tail 
bearing is NOT getting lubricated, the rear main bearing is NOT getting 
lubricated, the mainshaft is NOT getting lubricated, the syncros are NOT 
getting lubricated, but they are all spinning around.  For short 
distances, not a problem.  For longer distances, if you fire up the car 
for a minute or two every time you gas up the tow vehicle and still 
leave it in neutral to let the laygear splash the oil around you should 
be getting enough lube on the mainshaft and its components to keep it 
from burning up until the next stop.
