So are you saying that turning the tranny over slowly - e.g. by hand, or rolling the car - doesn't make and break inside the sensor unless/until it's spinning above 40 MPH? Offhand, I can't think of a failure mode that would fit those symptoms.

I have, on the other hand, owned a speedo head that wouldn't indicate speeds below 20 MPH or so on cold wet days until the cabin warmed up...
