Hello and thanks for donating


Does the speedometer read inaccurately, bounce around or not work at all? It is very possible that the little gears on the transmission that run the VSS have been damaged and are no longer giving the info. to the sensor. With the sensor itself being good, instrument cluster good and assuming wiring is good, I would put my money on that being the issue. You will want to check fuses if there is no voltage somewhere though.
