My 2017 Silverado High Country 6.2/8-speed is currently at the dealer for the fourth time since I bought it last December with this exact shudder problem. At steady speeds the tachometer constantly goes up and down by about 200RPM as the shudder comes through the steering wheel. GM told the service department to have me continue to drive it and see if anything changes. Not an option…
