It's not good to tow Esp. a AT tranny thats a good way to Burn it up. Plus it puts a heavier load on the motor/Lugging it. And you surly wouldn't have the power to Pass in OD (when towing)One thing I found out with my Van \:\( Vthing
Is that when towing In OD the MPGs die. It gets better MPGs when In drive Then in OD even On Flat Land not Hills.
Just My2cent.
It is nice to have the option of OD while towing. Just like in big OTR Semi's, some of eaton's trannys you could swap gears around and have a "Double Over" or two OD's instead of just one. No, you can't pulls hills in either one, but on the flat, and areas where you traveling down a small incline, it really shines as a fuel saver.

Of-course, a torquey engine will tear anything up, I could give speaches about 5.9(6BT) Cummins and NV4500's and towing in 5th gear, the engine can do it, tranny won't take it.

Love Old '67-'72 GM Pickups! Dare to be different.....Running GM Inliners, GMC's MONSTER V-6's, and real inline power, Cummins, in Central PA.
