“my 2011 fmc sierra 3500 drw denali suffered a failure of the Transmission Control Module (TCM). I could barely move the vehicle and almost got into an accident merging into traffic. Forward and reverse was affected. The transmission reverts to top gear after the failure, and makes driving very difficult. There was no warning for this failure Luckily I was minutes from my dealership. This problem could be bad.”
