57000 miles. I have driven 130 miles. Bought this less than 3 weeks ago, 5500 bucks on a 3500 pound paper weight. Trailored it to the local GM dealer i bought it from.Dealership drove it and did a ride along with me, the tech says its normal. Starting to shift hard. Now its 500 to 1000 rpm jump at these speeds 18-20 mph, 27-30 mph, 37-40 mph, 43-45 mph, 53-57 mph. All the shifting points. Two long stretches of road i drive 35 break kneck for 6 miles. Then another spot i drive 55 for 5 miles. Rpm's jump back and forth 2200 to 3000 constantly. Wish we had a lemon law. Take this [non-permissible content removed] back. Sucks i paid cash from dealership. Should have financed and let them repo.
