My 02 ford Taurus will not accelerate or reverse?

It will crank, go in gear but will not move. I had a transmission flush in March. As far as I can tell, there was no indication that there was a problem.Other than the transmission, could there be another problem?

Thats a big problem, If I were you I would buy a newer car so you have less problems. Because the more you fix this car the more it will break down and cost you.

Broken drive axle could do it.
