Shifter cable bushing became disengaged from the transmission. shifter lever floated freely through gears. when engine stopped, it would not go into park but remained in neutral and began freely rolling backwards in my driveway. emergency brake had to be used to stop the car. i understand this is a fairly common problem with this make of vehicle. this part should be recalled. *tr

Traveling on the interstate at 60 mph transmission shifted gears via cruise control and the transmission lost 3rd and 4th gears. when contacting onstar 3 different times they insisted it was safe to drive. then the whole transmission died. *nm
