LINCOLN: 2007 MKZ


ISSUE:
Some 2007 Lincoln MKZ vehicles may exhibit a hesitation during acceleration from a stop or at slow speeds. The vehicle may also exhibit a slow or hesitating upshift while ascending hills. A powertrain control module (PCM) and the transmission control module (TCM) calibration can be the cause of this concern.

ACTION:
Reprogram the PCM and TCM to the latest calibration.

I had the dealer apply this one and it seemed to improve the shifting. I had a lurch if I was rolling to a stop and stepped on the gas and on some hills the transmission seemed to stay in lower gear longer than I think it should have even if you took your foot off the pedal.
