I have a 1997 gt that I recently purchased which was all stock at the time. The problem is that the speedometer reads too high. If my speedometer is showing 80 I am actually going 70. I assume the gears are stock since the rest of the car was untouched and i am now running 245/40/18 and 285/35/18 rear tires which should be close enough to stock. I am guessing the speedometer is ok since it works. Any one else have a problem similar to this and if so what was the solution...? Could the speed sensor on the tranny be bad?

That tire is approx. 2/10ths of an inch taller so your speedo if anything should read slower. If it's anything better than a pusstang it will have trak-lok, jack it up and check the gear ratio for sure, I used to have something called an abbot box which can be used to adjust the speedo.
