Hello, I am new here and I just purchased a 2016 Silverado 1500 Z71 LT. My wife and I were riding to Walmart today on a slight incline on the highway and she asked me what is that vibration or studder? I have felt it before but thought it was just the road. It almost feels like the transmission and the torque converter not locking up all the way in my opinion. I have to take mine in tomorrow for some factory paint defects to get repaired so I will talk to a tech and see if there is any idea. I like this forum and look forward to being active here. My truck has less than 400 miles on it right now.
