This Problem Across All Years
On or about [XXX], the Transmission Control Module, FAILED, on my 2011GMC Denali 2500 6.6 diesel. It was a KNOWN faulty part .General Motors was aware of the issue years ago. This part should have been deemed a Safety Recall item. Imagine, pulling a trailer down a busy Freeway, with Semi's presence. Module goes out, truck goes idle, people hurt or worse. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When vehicle is warm and shut off, upon restart it will not go in to any gear, there was no warning lamps. An independent repair facility determined the Transmission Control Module was defective. General Motors has no parts available, and I know fro a fact it is a rather large issue.
TCM failed. Couldn’t find the parts required. Truck sat 700 miles away from me for four weeks. Had to have part repaired in hopes it worked. As of now I still have some issues but would not have the truck at all if I had to wait for a part
