Trailering button was not on, driving on flat ground, had driven about 30 miles before it happened. Auto shop drove it, said no codes. Beats me. Going to dealer nest week for Air bag recall, will ask them. Thanks

Driving in traffic, slowed and tapped brake for slow traffic, went to speed up and transmission had obviously shifted way down into lower gear, as I hit throttle, RPM's jumped to over 5 thoushand while moving about 35-40 mph. Pulled to side of road, manually shifted through all gear positions, took off, worked fine from then on. Any Ideas? Twice more this has happened only the transmission shifted into neutral, again shifting throught he gears made it go away EVERY time this happened, the Speedometer dropped to zero, so it must be some electrical probleme, SENSOR??? Took to GM Dealer for Air Bag Recall and told them the problem, they also checked codes, found nothing and did not seem to know what could cause the problem.
