I had a Lincoln which did almost the same thing. On my car it was the Alternator shorting inside its casing. You can get a free test at Autozone or Oreillys on the car.

Now mine did not return to normal when I put it into Drive. So on your car you may have an Electrically shifted transmission. I would think if the Alternator passes its tests, you have a short in the shift control module which is shorting the Alternator and its Regulator inside..

My Speedometer would read 60mph and the Odometer would count the miles when the car was sitting still. I replaced a Digital dash to no avail and then found the Alternator was the reason my Speedo and Odometer were acting up. Immediately after changing the Alternator all problems stopped for me.

99 ford Taurus won't go over 35-40 mph, however speedometer reads 120 mph from start. Tranny seems fine and no check lights whatsoever.


Scan the vehicle for fault codes first. Sounds like you need to check the vehicle speed sensor signal into the speedometer. If that is ok then send the speedo head out for repair.

Speedometer not working


my speedometer will work every now and then but most the time it will read all the way up to 120 mph or stay at the wrong speed its not the speedometer or the dashboard cluster that's been checked out its a 2007 Pontiac Torrent FWD 5 speed transmission and it runs great. What do you think it could be?

Speedometer is working but reading way off


It appears that you need to have the speedometer calibrated. Unfortunately, this is very challenging. You'll need to take it to a mechanic. Dependent on where you take your Envoy it can cost around $75+

Corrosion around the positive anode of the battery. Truck will not start, but battery is not dead. Jumped it with my other car. Drove it about 10 miles - herky-jerky for the first three, like it was...


Likely these problems were being caused by your electrical system being abused. You MUST pull the cables off your battery and clean both the battery and cables to shiny clean. Add a touch of vaseline to all parts and hook it all back up.

I looked down and the speedometer in my 05 Trailblazer said I was going 120 mph. When I stopped and put the car into park, the speedometer stuck at 70 mph. I need a simple, cost effective solution. Please...


This is a very common problem with Trailblazers and is caused by a fault speedometer stepper motor - the actual motor that makes your needle move around is wearing out.

You have two solutions, if your Trailblazer has 70k miles or less you can take it to your local Chevy dealer and they will replace it for you as part of a recall.

If you have over 70k miles visit my Trailblazer speedometer page here: http://drspeedometer.com/services-i-offer/trailblazer-speedometer-repair

Speedometer problems


It may be that the speedo cable has come loose at 1 end and will need to be tightened back up. Sorry but not sure where ends are attached on your car.
