Oddly enough that after I disconnected the negative from the battery for 5 minutes and reconnected it, a bunch of strange behaviors disappeared. The speedo has not jumped once for the last 250 miles I travelled. Before I reset the battery, the speedo needle was dancing like the VU meter on a highend audio amplifier. Now it is just steady.

I am still buying a VSS from TeamFord just for the peace of mind. It seems to me that the ECU has something to do with the speedo (or just a coincidence?) so resetting it fixed the problem.

If the plastic (old ones has plastic) breaks and ends up in the tranny, you are looking at $3,000 or so. For a $40 VSS, this is not a risk worth taking.
