It IS the manufacturers reccomendation to TOW IN OD. Consult a transmission professional, not smiley, not myself, and find out the specifics on why you can or can not tow in OD.
heat is the enemy of transmissions, if you can tow in OD and keep it cool I dont see it doing any damage, but every truck is different.
I dont really know how to say this, but Im kind of a big deal.....I mean, people know me. I have many many leather bound books and my apartment smells of rich mahogany.
Page 2-22 of 1995 Tahoe Owner's Manual (like I said - check your owners manual).:
0 AUTOMATIC OVERDRIVE (@) - This position is for normal
driving. If you need more power for passing, and you’re:
- Going less than about 35 mph (56 km/h), push your accelerator
pedal about halfway down.
- Going about 35 mph (56 km/h) or more, push the accelerator all
the way down.
You’ll shift down to the next gear and have more power.
@ should not be used when towing a trailer, carrying a heavy load,
driving on steep hills, or for off-road driving. Select THIRD
GEAR (3) when operating the vehicle under any of these
