Question about 2001 Chevrolet Cavalier
Cruising down highway , the( trac off )light comes on and trans shift s hard
If your ABS light is on as well, have a shop scan it (it requires a special scanner). If it's just your Trac light without ABS, it is most likely a sensor under the hood at fault. If you are getting a check engine light as well, get the codes read!
This happened to me without an ABS light and it was the upstream O2 sensor. The reason it throws the Trac light is because if any components that the traction control uses (ignition, fuel) are affected by a bad sensor, the PCM shuts down traction.
In fact, when I replaced the O2 sensor, a handful of other little issues resolved as well.

Go to your nearest Auto Zone store and have them put their computer on your vehicle, to see what code comes up (IT FREE). They should let you know what the problem it...if not....let me know what the code is and I will let you know what is wrong..Hope this helps you ??
