Speedometer Issue
My speedometer isn't working correctly on my 2003 Ford F150XLT 4x4 5.4L V8. The speedometer reads 100+ MPH in park until I am on on the interstate and starts working backwards. I understand that I have two speed sensors on my truck one on the rear differential and one on the transmission. I can't find what each exactly do, but the one on the diff is for ABS and other items. I cannot find anything on the transmission sensor. My vehicle is not showing any alarms. The odometer and cruise appear to be working correctly. Is this a instrument cluster issue?

The one on the transmission is on the rear output housing of the transfer case at the top. Have you tried giving the dash a smack? Occasionally mine just stops and that brings it back to life lol.
