    2014 Chevrolet Downshifting

    2014 Chevrolet 1500 5.3 6L80.
    The transmission seems strong with no issues until I try to maintain a certain speed. When I reach a speed that I want to maintain the transmission downshifts for a moment then shifts back to the proper gear. It will do this at any speed I try to maintain. I was advised to have the transmission rebuilt. Any ideas?

    Stock or modded? You can increase the torque model just a touch on the map side to keep it from trying to downshift.
