    Speedometer issue

    I was traveling about 50 mph, but the speedo said about 100 mph...and the
    odometer was clicking off like it was going 100 mph.

    Ever had this issue with a car? Know what is wrong?

    Electric Speedo? Maybe it's not switched to the Chrysler output rate?

    Then the next day it did not work. Sometimes it does and other times it says 120 mph when I am doing 50ish.

    It would be high on my list since it works intermittently and also reads funny when it does work.

    Re: Speedometer issue

    While changing the sensor you should check for the proper color gear based on your rear tire diameter.
    I don't have the info you'll need though. But you might try emailing Cliff Ramsdell or another tranny guy.
