Default Transmission line o rings

I'm replacing the radiator soon on the 01 dakota.
​​​​​will I need any o rings where cooler lines go in?

No, they should be fine, should come out in one piece.

No, the O-Rings do the sealing. I forget the name of the fitting, but it's similar to 37 degree AN fittings. Self sealing, dry threads.

Yes there is an O-ring on each line, but they should come out of the old radiator and go into the new one just fine, I never replaced mine.

Yep .
There were o rings on end of transmission lines,in fact one was missing on the lower line.
Half the size of a dime.It was tan.

Will the basic black o rings work fine mixing with that transmission fluid ?

Black O-ring should be fine. Hard to say what size they are. Most O'Reilly's keep O-rings in a little yellow box behind the counter. #011 is a 5/16 ID i know for a fact.
