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.

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

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.

Transmission control module put my truck in limp mode while drinking down the highway.

Dash is cracked in multiple spots making it a safety concern when airbag is deployed.
