Good to hear it's working for you. That sensor is used not only to operate the speedometer, but it is used as a sensor for the ECM to determine the vehicle load and when to drop RPM's to let the trans shift of course this also includes the TPS. Don't forget to give me some rep points, it's been awhile since anyone has gave me some.
If you ever have a problem with the truck my door is open.
