speedo goes to 100mph when ya put in gear and odo puts the milage on it like your running 100 mph even when your stopped or in park or any of the other gears, so i unpluged the vss and its still doing the same thing. so i pulled the fuse to make it stop any ideas where to look to fix it??

 

Sounds like the speedo itself to me.

 

Check the harness going back to the tranny and VSS.
