My speedometer will stick occasionally and will then start working and think that speed is zero. Usually it wil back itself down to zero once the van cools down.
I've replaced the transmission speed
sensor twice. That temporarily fixed the
problem for a couple weeks and then it
would start doing it again.
Sounds like the stepper motor for the speedometer needle is sticking. Unfortunately the instrument cluster will need to be replaced if that's the case. You can get a rebuilt one at your local auto parts store. Record your mileage and vehicle identification number (VIN) before you pull the old cluster. They'll need that information to order the new one. HTH. - Jim
When it sticks, the tranny also shifts hard, then is fine when it starts to work again. It seems to do it when I drive for a while.
