I have a 2020 Chevrolet Silverado 1500 LT 5.3L w/ 8 speed transmission. 76,290 miles on it and I’m having shudder problems. Everyday when I’m driving to work on interstate I will set my cruise control at 70-85 mph and the truck shudders. Stops for a couple seconds then shudders again I watch my rpm gauge and every time it’s about to shudder the rpm’s move up a little. So when I’m driving my rpm needle is constant moving up about 100-150 rpm’s and then boom it shudders and then rpm’s go back down and couple seconds later same thing happens. I never have a smooth steady rpm or smooth ride. It annoys the heck out of me but I have noticed it shudders anytime I’m driving at a steady cruise speed could be 30mph or 90 mph it don’t matter. it’s always shuddering. From a dead stop I smash the gas it will shudder when it hits around 3rd gear also. Can anyone please help me out and let me know if you’ve had same issue or what? Thank yall
