A: Actually, it is easier on the O/D because the faster it spins, the more 
lube is thrown around. If you are in the range of speed where your motor 
lugs, then economy suffers and the O/D gets under lubricated (bad thing) 
plus the ones in the Grand Cherokees require line pressure to stay engaged, 
and if the motor isn't spinning fast enough, pressure drops and clutch 
slippage wipes out the trans. Same thing with trans that upshift too soon 
while under load.

So, If you go faster you can tow in overdirve and that puts less strain on 
the unit??? I'm sorry, I'm not buying that one!
The only time I put my overdive transmissions in overdrive when towing is 
when I go down hill and don't need engine braking.
I will also use overdirve if simply pulling an empty dolly or utility 
trailer. I'd rather buy a few more gallons of fuel then a transmission!
  I've towed things I shouldn't have with vehicles to small for the load and 
always done so successfully. Just by being very mechanically aware of 
exactly what was going on and what to do and more importantly what not to 
do!
Maybe I was pushing my luck with the 4 hour tow back from Columbus Ohio with 
my 65 Ambassaodr convertible on a dolly, backwards with it's top down! 
Behind my 96 Cherokee Sport. Boy did I get some looks that day!
