[77newell]

I doubt you can do any electrical or mechanical damage by continuing your trip as is. Whether your pocketbook will suffer due to speeding violations will depend on alternate speed indications. I drove from Texas to Michigan this spring using a GPS for speed indication, the only problem being that my old eyes and the small speed readout were somewhat incompatible.

The speed sensor arrangement will vary by coach. On my 77 coach the speed sensor was mounted to the left side of the HT-740 Allison transmission. On my 93 coach the signal is supplied from the Allison HT-741 ECU.
