It's happened to me on the highway numerous times.. I'll really lay into the pedal to accelerate, going down into 3rd (4-spd Auto) and all of a sudden the gauges go WACKY. I mean, the speedo will blip down and hover around some low number like 50 mph and the tach doesnt show close to redline either. when in fact, it is coming right up up the redline before it shifts to 4th. (foot still down to the floor basically) And at some random point, all the gauges blip back to the correct positions, showing me that i'm right before the redline and that im actually doing 90 at this point. VERY STRANGE. any help guys?
