I have a 96 astro all wheel drive that when your driving the speedo reads almost double what your actually moving. And when the needle is up to 100 and I'm moving about 45-50 the fuel cuts off just like it hit the governor. And if you dont mash the pedal all the way down while your accelerating it shifts really weird like it shifts up then down then up then down.

sounds to me like like a short in the vehical speed sensor.it controls the speedometer and the computer also uses it to tell it when to shift.
