2007 GMC Acadia drivetrain & axles problems

Tl* the contact owns a 2007 GMC acadia. While the contact's 5-year old son was inside the vehicle, the gear shifter was switched to the neutral position. The vehicle rolled down an embankment and crashed into a creek. The keys were not present in the ignition switch at the time of the failure. The occupant sustained a bruised back and left arm, which required medical attention. A police report was filed. The cause of the failure was not determined. The manufacturer was notified of the failure.

Our 2007 GMC acadia began slipping and stutter stepping in reverse. If on a hill it was very noticeable and felt like you were slipping on ice before reverse gear would engage. Then on slow acceleration form a traffic light slippage would occur and a rough change in the gear exchange for normal traffic speed. Had it diagnosed at a reputable local repair shop and they said it was a warped wave plate and a new or rebuilt transmission was required, the repair cost with warranty would be 4,225.00.
