Crazy VSS, Help!
I've been getting an intermittent VSS issue. Sometimes my speedo jumps all over when the car is in park. It seems to be fine in gear and will stay at 0 if I am on the brake. Once I put it back into park it's bounce every where from 0-70mph. This shows on the speedo as well as the datalog in Tuner Pro. I've already changed out the VSS, VSS Buffer and Cluster.....HELP!

Re: Crazy VSS, Help!
I had a 700R4 in a blazer that was doing the same thing. After much headache and frustration I found that it was a ground problem.
Not sure that is your problem, but mine was acting the same way and thats what my problem was.
