Sounds like the speedometer is faulty. If the speed sensor were the problem, the odometer would not work correctly, the transmission would not shift correctly, and the check engine light would be on.
Its a loose connection on the speedo cable. its a b*tch to get to. I had the same problem on my truck, it would fluctuate in 5th gear on the highway. i spent the money and had a professional do it.
have the fault codes read
the speedo gets its signal from the VSS ( vehicle speed sensor) and that sensor also reports to the transmission control module
So check for a problem in that area
check your speedometer cable it runs from your transmission to your speedometer it is what determines your speed if that cable is loose from your tanny then push it back in i hope this helps
