2003 Chevy Trailblazer 6 cyl Four Wheel Drive Automatic 92,000 miles
Car starts up fine, went into reverse 200 yards and stopped. Shifter will move but not engage the gears. When I put it into park a loud grinding noise is made. I moved the shifter a few times to see if it would " catch" and now it won't even go into park, we have to use the emergency brake! Any idea what this could be so we don't get taken for a ride at the local repair shop.
