speedometer will not work

[go-stang5.0]

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?

It just says to remove them. Last time I had my cluster out, I couldnt just pull them out. I figured there was some trick to it.

all you have do is undo the 1 screw and use a flat head, knife,anythings that flat; and pry it up just dont pry to hard that what i had to do when you get to the gear make sure you get all of it out orelse it will break the new gear myne was like gum, squeshy

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?

I had the problem in the past and the speedo gears, not the ones of the VSS, were all chewed up. This happened after I had the 3.73s installed. My speedometer would work sometimes and then not work and then the needle would swing crazily. Replaced and never had a problems since. I bet that's your problem - the speedo gear.
