    I own a 2006 F-350 psd dump truck. While traveling to different driveway to plow I notice that my speedo was not registering. I was stuck on zero while I was traveling about 30mph. That was two weeks ago. Since then, there have been no problems at all. Should I be concerned or just was it a fluke? I have not had any problems with the truck since I purchased it. Thanks Mike

    I think I have heard of about 15 people who have had problems with their RPM or MPH gauges reading faster or slower then they really are going. My friends trucks reads 5k on the tack when hes going 30 MPH. I don't think have heard a reason why they are doing that yet...

    Same Here

    I had the same thing happen to my 06 F-350 during our big storm. It only lasted until I stopped to load salt & then it started working again with no problems to this day. I think the sensor is in the rear end housing & ice somehow caused this.

    Next time it happens--check the sensors (wiring may have gotton wet/cracked /corroded) on the tranny and rear-end--- I know on the older ones 99/03 --the rearend sensor -- would give you a fault code for the tranny and give faulty readings for mph-- can't remeber-- been about 4 years --You guys should still be under warrenty?
