HELP!!! Speedometer Fluctuates
Well it seems that I have a problem that stumps some people. I had recently done a cruise and and came back to find the my speedometer would bounce quite a bit until after 35mph. It had seemed to have fixed it's self for a couple of weeks but now it's back. I had taken a trip to Houston about 200miles and everything seemed fine until the trip back when it just dropped to 0mph, and over the drive back it would bounce back and forth from 0 and the correct speed. I wasn't too concerned about it to start with and hoping that it would fix it's self again but it doesn't look like it is going to. Now because of this the whole car is acting weird where it hits the rev limiter around 5500 and I have to reset the code every time I want to put the car into reverse, now that's just annoying. I pulled the rear wheels and checked the rear wheel sensor connectors and all seemed fine, then ran the car while in the air and would not start sensing yet still bouncing after 70mph. Any help much appreciated.

The VSS (Vehicle Speed Sensor) is what you need to look at and it plugs into the top of the differential, this sounds like the most probable cause considering everything you say it's affecting.
