My 2003 chevy Tahoe z71 transmission failed while driving. The transmission would not engage at all after the incident. Vehicle had approx. 70,000 miles. The transmission was repaired at the gm dealership. I still have the parts available. Gm dealer nor the chevy customer service line would acknowledge this as a issue on the Tahoe. The incident occurred in a main road with significant traffic - it had the potential to be a safety issue as I was making a left hand turn when the incident occurred. 4l60 transmission.
