alrigth well lately the speedo in my truck has stopped working, it all started when i spool the turbo at the lights and take off squeeling the tires, is this just coincidence? or has this done something to the gear or machanism that reads the speed? where could i start looking?

Look for a wire going to the speed sensor on the tranny because it goes across the tranny and close to the exhaust and after that pull the gear out and check it.

Does the odometer still work?

My guess is that the VSS is laying on the crossmember...

I replaced my vss three times only figure out that the wiring at the plug was bad all along.

thats funny i was comin home from my property up near up state ny and i came up on a powerjoke and of course i had to hit it....well all of a sudden my speedo went from 80something to 0 i pulled off the next exit looked underneath and sure enough there was this little thing dangling down from a wire hooked it back up on the trans works great ever since

my kilometer dial also has stopped working so it dosent show how many K i have put on, it worked just before the speedo stopped working.

if you replace the vss get one from the dealer iwent through three from the regular parts houses, thought it was the wiring, checked good, the dealer one is the only one that has worked for me.

Sounds like the VSS is not working. Check to see that it's actually still hooked up, and that the drive isn't rounded off.

so this means i gotta take apart my dash to get back there and see whats goin on? i have never replaced the VSS before

No, the VSS is on the side of the tranny. Drivers side above the crossmember if its a getrag 2wd. Not sure on the others. Two wires coming out of it heading up and over the tranny to the front of the truck.

Can any body tell me what color the wires are going to the plug when I got my truck the wires where pulled in half and there four wire two go to the nural safty switch and the other two go to the speedo sensor sorry about the spelling.

my trucks 4x4 could the plug be at my transfer case? because i also have a 618 transmission from a 94+ truck and all that i plugged into that was my neutral safety switch. and there is 2 plugins on the transfercase one for the indicator lamp on the dash, and the other i assume is for speedo.

wannadiesel

Yes, your VSS will be on the transfer case. It screws on where you'd expect a speedo cable to go.
