THIS IS MY FIRST POSTING SO BEAR WITH ME. I have a 1991 Dodge Ram Van B-250 318 automatic. My problem is that my speedometer is erratic and some times stops working all together. When it stops working my van will not shift into overdrive. What might be my problem?:

Not real familar with your model, but it is possible there is a speedometer sensor connected to the tranny which could cause the problems like you are experiancing. Hopefully one of the more experianced members could chime in.

I agree Danrak...that sounds like either a bad vehicle speed sensor or some bad wires going up to it.
Are you getting a "check engine" light on it John?
