1998 Plymouth Grand Voyager Bucking with Speedometer going haywire

    I have a 1998 plymouth grand voyager with the 3.3 liter 4 speed
    automatic transmission with about 100,000 miles on it.

    At about 95,000 miles we had a rebuilt transmission installed that
    carrys a 3 year 36,000 mile warranty. Ever since we have had the
    rebuit transmission it seems that the shifting is a little more
    pronounced (e.g., upshifting and downshifting at different speeds).

    In any event, today my wife told me that the Van bucked a little as
    she was pulling into a parking spot and the speedometer went up to 50
    miles per hour and back down again. (Sort of haywire) She said that
    the bucking occurred a couple other times while driving and each time
    the speedometer meter went haywire.

    I test drove the van when I got home but could not replicate the
    problem my wife described.

    I plan to take the van back to the transmission place to have them
    look it over but was wondering if anyone knew what this recent problem
    could be.

    Thanks In Advance

    You need to replace the speed sensor. My was worse when hot. Symptoms
    just like yours.

    Take it back to the place that put the new one in and they'll fix it under
    warranty. It sounds like a bad output speed sensor.
