Have Truck Repair Questions? Ask an Expert
Hi I'm Wayne
I will help you with this
did you have the ECM checked ??
VSS gives signal to ECM, and the ECM gives signal to the
speed gauge , I suggest to have that checked
I hope this helps you
Yes I would take it else where
I did not buy that Turbo story , when reading this

That is the only way I get credit for the question
or the money you paid stays at JA and I get nothing for my time.
