So my 2023 transmission has had issues since I bought it with 6k on it. It has the same issue as described in this forum shuddering, harsh or erratic shifting and jerking. At time it not that bad at low speed but once 30-50mph it happens regularly although i can point to time at low speeds and high speeds. I have brought it to dealer twice. The first time they "checked the codes etc" and could find anything. The second time i drove it with manager and he drove and could not create it, although i also understand how to minimize it occurring. So the 3rd time brought in they "cleared the codes and could not find anything and when drove it it was fine"...... It is not fine and this weekend if final straw....I let me neighbor borrow the truck and about 30 minutes after using it I got a call and he asked me if the transmission was suppose to be "randomly shift and shaking, or did he have it in 4wd or was doing something wrong.....How can i get this resolved while still under warranty and why has there been no recall on this as there is forum on this site with same issues, and well as reddit and other locations......How can I get GMC to take responsibility and fix this issue?? Help???
