I have a 2014 chevy silverado ltz brought new and about 5 weeks ago it started shuddering. I have had it to 4 different garages, transmission fluid changed as well as filter. Drove it almost 2000 miles after change and it did not shudder once. Got home and it started shuddering really bad. Have appt with chevy garage Friday to see what they can do. It seems like its worse now when it tries to change gears and it is automatic.. It has less than 80,000 miles on it. Do not want to put rebuilt transmission in. Any suggestions.
