Experienced the transmission shudder and had the tranny fluid changed in early Dec '23 with 43k miles. It rode like a dream for about 1,000 miles but is back to it's old trick. Just talked to dealership who said my Powertrain Warranty expired two weeks ago and it needs a torque converter for a truck that has 45,000 miles. I am so f'ing mad I promise you I will never buy another Chevy and do everything in my power save my friends from a similar nightmare. Did I mention it was a $66,000 truck in 2019 and this is what I get...Has anyone had any success appealing to GM customer relations on this issue?
