• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

crazy speed odometer

2001 gt recently started jerking, at highway speed .and the speed odometer would go up to 90 mph when your going 55-60 mph it did this a few weeks ago and i replaced the icm, crank position sensor, and different coils. this seemed to fix for a while, but now i am back to square one. i do not want to throw more parts at it ,without more knowledge or $$! any body had this problem or a ideal what this might be thanks.
 


OK its been a few days .cant believe someone didn't chime in with some stupid ideal .even that would have let me know that this is a serious site! thanks for nothing! bye the way i did figure this problem out, but it wasn't posted from GP site! it was a wss.
 


ok so maybe i didn't know the difference(apoligize) but you would be right it is vss. the wss controls abs and trac i know this now and also the vss controls speed odometer and tell trans when to shift

I can assure that the knowledge on this site is far superior - as a collective - than any other GP site that you will find. One big contributor as to why you didn't get an answer was the fact that most - if not all; of our local group (KCCGP) wasn't doing much "board surfing" during the week you posted this - we lost a member and good friend on the 22nd very unexpectedly. And besides, we're all smarter than EVERYONE else. :th_jester::th_laugh-lol3::th_jester:

But seriously - you won't find a better (collective) forum for your questions - from simple to highly technical - than this place here.

Oh - and yes; you're problem is text book VSS failure. :)

Glad to hear you got it figured out, and don't hesitate to post up again with any questions/problems you may have.
