Shifting issue 3.8L V-6

I have a 1999 Pony with 138,00 miles to it. I have been using platinum spark plugs new wires, all fluids are topped off, transmission fluid looks nice and clean on the dipstick.
Now I have tried to disconnect the battery for the night twice so far. The first time it started shifting like new, until a week later. Now I disconnected the battery again yesterday and it was unplugged for about 18hrs. I put the cable back on and started the car and let it idle for a few minutes taking it down the street and it started shifting at about eighteen mph instead of eight or so. And this is from first to second. I can start driving with the automatic selected in it's second gear instead of the overdrive gear so once I get it up to twenty five miles per hour I just let off the gas and bump it into the overdrive gear and it's normal.
I can get the fluid and filter changed for about fifty dollars by a friend at the ford dealer. What do you guys think I should do? I'm really starting to think it's the main computer instead of everything else on it. I'm a gentle driver as I have a '76 Bonneville brougham that is a nice big body so I like to drive my cars easy because of that one.

if you have never change the trans fluid probably dont... if its been neglected this long it wont help to go and change it now.

It does take time to relearn the shift point they say when the battery is left off. You might consider a tuner to modify shift points~
