torqueflight trouble!

I am so bummed. I just got my motor put back in and got her running forthe first time in a very long time. My trans cooler line was squirting and the car was driving when thepush button was in N. I got the two rear wheels up in the air and when i fire her up they start to spin. When i give her gas they dont spin much faster. She does this in all gears, even reverse. I dont know why . can some one give me some ideas on what to do next. First i may need to put a new radiator in because the cooller male in broke off in side the radiator. im going to try and rethread it, but, im not sure that will turn out the way i want.
