Verified

The speedometer may stop functioning with code P0722 stored in the powertrain control module (PCM). This may be caused by a worn speedometer gear due to coolant contamination of the transmission fluid. If contamination is found the radiator is most likely at fault. The transmission should also be thoroughly inspected and repaired or replaced as required.

    Car bogged down like it mas similar to a misfiring, then I noticed the speedometer was at 0. After downshifting at a coming stopsign, it bogged again & the speedometer picked up again, only to fizzle out again as I accelerated.
    having the mechanic repair the speedometer as we speak... mechanic is concerned there's more to it...

    I have an automatic, but yes, radiator went bad, and I have to replace my transmission due to coolant mixing with the trans fluid. good thing I bought the top of the line warranty, or it would have been all my expense.
