make sure you have the speedo ring gear on the diff of the transmission, without, it wont work

did you use the same vss or the one that was on the vss tranny? try using the one off the y8

the speedo ring gear is the gear that turns the VSS. if you pull out your VSS, you'll see that it's gear driven similar to the distributer setup on an old V8. if you're missing the ring gear, there's nothing to turn the VSS and therefore no speedo.

in all honestly, i doubt that would be the problem -- unless somebody pulled the gearbox apart and reassembled it incorrectly. it's more likely a bad VSS or a wiring issue.

 

well all i ddid was unplugh it. but when i pull the codes i got vss. no i replaced the vss with a known working one from my old tranny and still haveing same prob

 

Pull the harness plug from the vehicle speed sensor.. There are 3 prongs.. make sure they are all still in tact and not broken off inside the plug.

This is a common problem.

 

i got it to work i had to change both piece of the vss the vss it self and the plug part.
