While in limp mode the truck would not respond to throttle commands. Truck slowed to 20mph causing a disruption in traffic flow and making it very difficult to get off the freeway, dodging traffic. The TCM failure has been confirmed through a local GMC dealer (Dennis Dillon in Boise Idaho).

Very limited parts are available on Ebay (10 or less) . Dealer price for the TCM is $710....
