Truck went into limp mode. I heard a sound like air coming out of a tire and then the truck wouldn't drive correctly as if the transmission was holding back. The dealer flashed the transmission control monitor.

Replaced TCM which was located inside the trans case. It took 3 days to do this repair, but they gave me a loaner. It improved the trans shifting by 100 %. The truck actually accelerates faster and smoother than it ever did. Very pleased with new part and upgrade.
