Broken gear shifter cable
Automatic transmission shift lever cannot be shifted from its "park" position upon starting the engine and trying to drive away. applying the brake pedal in order to disengage from "park" position of shifter still won't allow lever to be moved from "park". the electrical circuit can't be completed to allow disengagement of shifter. this happens perhaps one out of every six or seven times you wish to drive the car. one must sit and make several attempts over several minutes to free the shifter. very embarassing if you are in a line of cars at a gas station or fast-food take-out line. many other corvette owners have this same issue from years 2005 up to 2013.
