Model Years Affected: 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011

Drive Trains Affected: Automatic Transmission, Manual Transmission

Average Mileage: 87,809 mi (28,000 mi - 260,000 mi)


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.

    When driving the highway my speedometer went out and my digital odometer was still visible but it was no longer changing. The check engine light had also come out so we went to auto zone to get a general diagnosis. We were told it was the outshaft speed sensor so we bught the part and had it installed however that did not fix the problem. We took it for further inspection and were told that some coolant may have leaked into the transmission, damaging it. So at least we know whats wrong with it however it will be costly repair.
