Hey all, going up I-75 towing the Rockwood TT, 9000 gvwr, with our 2024 gmc 2500 6.6l gas at 65mpr. 

Stopped at a rest area for a few, started back on the highway about a mile and truck jerked, disengaged tow haul mode, and went from 2200 to around 3800, and the check engine light on.  Any Ideas what caused this?

Later-

you would need to get a code reader and check what codes the ecm is generating.  I would use one that can also get tcm codes.
