Anybody knowledgeable on Ford Transmissions?

If so maybe somebody can help. I have an '88 LX Mustang has a 5.0 with the AOD.
When I drive it around town and put it in O/D and keep acceleration around 45 mph maybe a tad less the car seems like it's not sure if it wants to go into o/d or stay in drive. If I drive on the interstate 50/55 above no problem. know I can drive around town in Drive but will that hurt my transmission? The car is equipped with a 2.73 rear. Thanks for any advise. BTW the transmission was rebuilt before I got...
