Drive Trains Affected: AWD, FWD

Average Mileage: 87,785 mi (29,500 mi - 180,000 mi)


The automatic transmission may develop shifting concerns. On lower mileage vehicles, upgrading the software in the powertrain control module (PCM) and the transmission control module (TCM) may correct the problem. As the mileage increases, internal transmission damage can occur. Repairs could involve replacement of the valve body or a complete transmission rebuild. Whenever major transmission repairs are made, it is important to be sure the PCM and the TCM have the latest software updates to help prevent these issues from reoccurring.

    This is a random intermittent problem that cannot be purposefully duplicated. Occasionally, the transmission will shift so harshly that it feels like I've been rear ended. It will continue to do this for a few minutes and then the problem goes away for weeks. Still under the drive train warranty for another month and half, so taking it to a dealership.

    Problems shifting, especially when going up hill.
    Although my car has 160,000 miles on it, it's been doing it for probably 30,000 miles.

    Downshifting very hard! Valve body was replaced under extended warranty. Shifting normal now. At the same time my air conditioner started blowing one side hot one side cold.
