    Hey Bigmac, I believe you when you said you have been all over the shudder issue. I am experiencing the same with a 2016 Yukon Denali with a 6.2. I bought it a month ago with 20,000 miles. I've had motor mounts replaced, but am definitely feeling the shudder under light acceleration as described in 16-NA-175. It seems like the most common dealership response it "Can not duplicate"

    Suggestions?

      I made a visit to the dealership, they are very aware of the problem. I am told that there was some sort of update coming next month. I am also told that GM has bought back several

      Let me know please how it works out. The 2019 8 speed have  a new and different converter possibly to address this issue. I would be surprised they continue to make updates for the 2014-2018 8 speeds.  As noted I love my truck and tows my rv very well except for tq chatter.  Stay in touch please with updates ??

      Maybe they will use that torque converter on the 2015 and 2016. I will let you know what they come up with. As it stands, the vibration and trembling is not acceptable for a 75+K SUV.
