Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
Has the check engine light come on with this issue here?
Did the dealer check the data signals in the instrument cluster with a compatible scan tool to observe the speedometer signals to see if it was dropping as well matching what the gauge did?
Let me know,thanks Pete.
