    any real solutions to all the above complaints i have a 2015 sierra denali 6.2 that at a red light shakes bad in seat only as day goes on in morning its fine once up to temperature the problem starts! Anyone have dealer put coil pacs or wires on it, can it be a torque converter? I'm at my whits end with this truck and about to trade for a toyota truck which is a shame love the truck when liberation starts hate the truck. gm corporate has been useless on this issue

    first post to this board hope someone has had similar problem and a solution. i have a new 2015 gmc sierra 6.2 denali with 9000 miles that at red light shakes seat console at a stop in gear its intermittent but gets worse longer day goes. I can bump into neutral it goes away in park goes away in drive shakes at a stop. Took to dealer put washers in both mounts did nothing to solve issue.Took back said they re programmed the torque converter not sure about that one , it did nothing to fix problem. Any ideas? Should i push for new trans and torque converter? thanks john frustrated owner
