Ok, so when I got 50+MPH I can hear a high pitched squeel from my engine and my car will stay at like 2500 RPMS the entire time I am on the highway, no matter how fast I go...I think its my overdrive not working??? If it is does anyone know If the entire transmission needs to come out for that to be fixed on a 2001 Grand Prix 3800 motor????
