Vehicle shifts very hard in and out of 1st and 2nd gear. When starting to go at low speeds the vehicle almost stops when shifting and then jerks when it shifts. Same occurs when slowing to a stop. Vehicle was taken to the dealer and the power train was reprogrammed. The issue was a little better for a while. A few weeks later the same issue appeared again. Vehicle was taken back to the dealer in january 2020 and there is now a check engine code. Dealer plans to change 2 harnesses and change the fluid. Unfortunately the parts are on back order which kind of tells a story.

While driving down the interstate at 70 MPH my service traction control message, service stabilitrak message, check engine light, and reduced engine power message came on. The vehicle started running very rough it would not go above 50 MPH. I drove approximately 3 miles to get off the interstate into the gas station parking lot. I turned it off for about 10 minutes when I turned it back on only the check engine light was on I took it to the shop and they ran tests and said it was the battery. Two weeks later it happened again same thing when I turned it off it worked fine after sitting for 10 minutes I got home and when I got a chance to look at it to days later the check engine light was off. I have read a lot and forums about people having the same issue but no resolution truly being found. This is a 2011 gmc sierra 1500 with the all-terrain package and only has about 60,000 miles on it it gets oil changes regularly. This really makes me think this is something gm should look into.

Issues with emissions switch. Check engine light will not go off. Also 3 and 4th gear are completely gone out. I do not tow or have had anything even remotely heavy in this truck. It's a 2005 gmc sierra with only 78,480 miles on it. I am not the only one having issues with this 4 speed transmission. It is not heavy duty enough for this size truck.

The vehicle that was behind me slammed on his brakes to avoid hitting me. This problem with the transmission is going to kill someone.
