Do you feel it shifting? Sounds like it's stuck in second gear. That's "limp-in" mode that allows you to drive it slowly to the repair shop. It should never be driven at high speed like that.
The Check Engine light should be on too telling you there's a problem. That also means a diagnostic fault code has been memorized in the engine computer or the transmission computer memory. Those codes will lead your mechanic to the circuit or system with the problem, not the specific part.
