hey guys I got all kind of problems here. I got a regal with a 231 v6 and a th350 transmission . The car will not move in drive . I put it in park switch the car of and I can still push the car, I put it in drive and I also can still push the car. I jacked the back up and spun the wheels by hand , both wheels spun and the driveshaft spins, I know its not the rear end. is it my transmission? thanks for the help..
