Speedometer reading 12mph when stopped
01 f250 7.3 auto 4x4
As the title says, the speedometer is reading 10mph when sitting still, and when you go from drive to neutral it surges to 1000rpm. Also won't go into 4lo.
When under 10mph the speedometer is buggy, fine when at 10mph and above.
hooked up my bosch, and it reads the same, so is the speed sensor bad?
this happened after I put my truck in drive and drug it backwards with a winch to stretch/wind the new cable on the winch.
If it is the speed sensor, which one is it?

So I jumped in the truck to go to the store, and it decided it wanted to work right again. No lights, the speedometer worked right, no revving. Don't know why its working right now, I just hope the ole beast keeps her quirks at bay for the time being.

It might be metal from the normal wearing of gears stuck on the tip of the VSS. Pull it out and clean it.
