This happened to me 10/14. The part below the shifter that physically changes the gear position on the transmission disintegrated. Mine happened to be in "park". Tow truck driver was unable to pull Hummer up on his vehicle due to all wheels being locked. He manually shifted the gear to drive from beneath the Hummer in order to tow it. Repair cost was a little below $300 for parts and labor.
