I disconnected the battery and the car hesitates to shift now. Is the computer trying to relearn the car? Never had this problem when disconnecting before.

would double check the battery installation...Black has TWO cables one to the Block and the Red has more then one connector too~ a looper from the alternator and perhaps another auxilliary connector too...would have to look at the pictures..but am suggesting the battery install left one or more key components...wires...connections off~ (one guess)~

Well all this hesitating started when the alternator went bad. Shifted fine when the it went bad. They after a new one was installed it started to hesitate real bad. Got better over time except when it would shift to 2nd. All the other gears stop doing. I disconnected the battery to clear a service code and forgot it was gonna hesitate real bad.

Battery is only 8 months old

voltage should be 12.5 Volts~ regardless of the age, as long as it isn't 10 years old...and will take a charge~ as far as the connections...walk back your steps...perhaps a connector is undone~ really wish there was a way to actually see how it's connected (or not connected)~ alternator BAD...a lot of these rebuilts are not all that~ take it back if it's not putting out the voltage~

Scan for trouble codes to see what the car is telling you. Have the battery load tested if you suspect its faulty. Unlikely though. If nothing shows up take it in and have the transmission looked at. It's getting to be an old car, you may have transmission problems brewing as well as the electrical issues you've been dealing with.

Could there maybe dirty connection or something like that?

Well if you suspect that connections might not be 100% you do need to go over them and check. Modern automotive electrical systems are very sensitive and all connections, power sources etc. need to be pretty much perfect for everything to function properly.
