speedometer will not work

how did you check the VSS? Did you try to stick your finger in the VSS hole (on tranny) to see if the speedo drive gear is in the right place. When I put a 23t driven gear in it chewed up and moved the drive gear to a spot where no gear would contact it. I would stick your finger in there and make sure it hasent shifted from its proper spot...it only takes a sec.

my speedometer has been an on going problem.as of now the needle is all the way to the right.when driving at highway speeds it rotates counter-clockwise til it hits 100-110mph,then stops.sometimes it will operate normally,but most of the time it is exactly as i described.the odometer works,so does the trip counter,tach,oil pressure,coolant temp,volt gauge and fuel.vss checks fine,and the speedo gear has been replaced.pulled tranny wiring harness checked all wiring,fine.the only thing that did not look good was the vss referance voltage,repair book says the grey/black wire should have around 5 volts,mine checked in at 1.44 volts.what would cause this and how can i fix it?

Not sure what the VSS is, but did you check to see if the teeth are still good on the speedo gear in the tranny?
