dont freak out dude, it could be a fluke. My trans is different but one time after a hard left turn while accelerating made it stick in 1st, long ride home. Was freaking as you, checked everything and seemed good. Unplugged the battery while checking things and put it all back together, all was fine, trans shifted fine. Maybe a sensor is telling the trans that the engine is cold and holding the gears? Idonno just dont freak.
