The transmission failed at only 45,000 miles. Had truck towed to dealer. They diagnosed the problem to be a broken forward clutch. Vehicle was out of warranty (6 yrs old), so we contacted gm directly for assistance. They refused assistance, due to age of the vehicle, ignoring the fact that it only had 45,000 miles on it. The repairs cost nearly $2,000. Gm also refused to warranty the labor costs of the job. The warranty after the repair job only covers parts for 12 mths / 12,000 miles.
