yup...pricey too, about 370 bucks. but try a speed sensor first, if that dosent do it then check the tone ring on the rear diff.

i replaced the speed sensor on mine when the speedo was
not moving. after install speedo would jump around. turned out
to be bad wiring harness.

hmmm...so many ideas...i guess ill do some trial and error. Its just real strange because it i set the cruise at 54 its fine, but if i set it at 55 or more, you can watch the gas pedal jump up and down. i dont know...thanx for the info guys.:thumbup

if you havea scope you could hook it up to the wire through the cab, and take it fro a test drive to see the pattern the sensor could be giving off, but most poeple dont have the tools for this...
