I have a GT automatic, and the speedometer jumps up to 55mph as soon as I start moving and stays there, regardless of whether I'm doing 15 or 80mph. I have to use a stupid GPS that reads my speed to know how fast I'm going. Tachometer works fine. Once in a great while, it will jump up to real speed for a short time, then eventually settles back onto 55. The odometer recently froze, so I want to get everything finally fixed at the same time.
Anyone else ever have this type of problem? It doesn't jump wildly like some I've read about on this forum, so not sure I can really use their solutions for my issue. Any thoughts are appreciated.
