2000 Excursion flashing OD light and Beeps

[derekmj64]

I am having some issues with my '00 7.3 excursion. The overdrive light is flashing and there is 5 audible beeps to follow. I just changed the VSS with a motorcraft one and after I clear the codes then take it on short drive the light flashes again (I have cleared it and drove it 3 times with the light still flashing). The check engine light comes on as well reading P0500. The speedometer is functioning normally and the trans is shifting fine. Also there is no abs light on and the breaks feel fine. Hopefully someone has had this same issue with a solution.... I appreciate anyone's solutions/troubleshooting. Thanks!
