If the transmission shop did their job right then the transmission should shift and work like a new one. I would take it back and insist that they pull the transmission again and fix what they obviously screwed up. If they refuse then become a pain in their collective back sides. Call the better business bureau about them if you have to. You spent a lot of money to have this transmission repaired and they owe it to you to get it right or to give your money back so you can take it somewhere else to have it repaired. Good Luck!!!
