Make sure the vehicle will move in neutral. It should roll easily. If not, you have one or more brakes sticking. Make sure the emergency brake works properly.

If the trans engages but does not move until warm, it certainly is slipping or you have a torque converter problem. You need to take it to a trans shop for a proper diagnosis.
