Hello,I was driving the car and the light came on and it wouldnot go anywhere I had to floor it and the motor was at high rpm to get home.I read the manual and it said it could be the transmission control module or the gearbox?I was woundering if someone could help me out and tell me which one is wrong and where the part is locatated.Thank You so much

You say the light came on...which light? The yellow "transmission control light"?
