From the information that you have presented, it sounds like the transmission may be the problem. If the tach is running up correcponding to engine sound, and the car is not accelerating, it might indicate that the transmission is slipping.
I would start by scanning for codes. Not all transmission problems will light the MIL light. That is, the "check engine" or "service engine soon" light.
