“Transmission has a bad vibration at low RPMs under acceleration as well as slipping and hard shifts. A few times the transmission has locked up the briefly. It also runs very hot between 180 and 249 degrees. Have been researching this when I came across all the problems and recalls however nothing listed for my VIN”
NHTSA complaint #11655726, filed 2025-04“Breaks and/or drive train. It is available for inspection. 1) Breaks sink causing slowed break time and decreased breaking ability. If the breaks are pumped , more often than not, they will come back up to full pedal. However, in an emergency breaking situation, there is not time to pump the breaks. I was nearly in an accident recently when the break pedal would not stop the truck in time, due to the soft break pedal. I literally had to steer to the shoulder of the road. …”
NHTSA complaint #11630713, filed 2024-12“Nothing has happened so far but I believe they have an issue with the Allison transmission.

Walton Beach, Florida and they kept the truck overnight and said everything seems to work as it should. I just traded my 2021 gmc 3500hd dually with 130k miles on it and never heard that or ever had an issue so I'm not sure what changed since then? I'm not sure what you guys can do to look into it? …”

The error codes are P0700 and P0747 The Engine and Transmission System is not performing as expected. An issue has been detected in the Transmission System that transfers power from the engine to the drive wheels. …”
