The problem with overdrive is that, on hills, the engine will be
downshifting into 3rd, then back to 4th. It's doing this because you're
using too much throttle (in it's estimation) to maintain your speed in 4th.
This hunting back and forth is what's bad for the transmission. I-95 is
pretty flat, so I wouldn't worry about pulling with overdrive on (especially
with only 1,000lbs. Ever have the van full of people and cargo, and run in
overdrive? Same deal...). If you notice the transmission downshifting into
3rd, then back to OD, then lock out OD until you're back on flat ground.

No - but the constant shifting, combined with the torque converter
unlocking, will raise the temperature of the transmission. That's why you
want to lock out OD if that starts happening.

You're being prudent, but there's a bit of paranoia starting to creep in.
Just hook it up, drive it, and be mindful of the transmission. You'll be
fine.

if your really worried about it just change the tranny fluid when your
done. but 1000lbs might as well be 4 big guys in your van.
I"d sure look into a trans. temp cooler.
It's got to be less expensive than a new transmission.
