trans electrical problem

[chief301]

I own a 2007 1500 classic and having trans shifting problems. Checked the codes and found several codes stating open circuit. Truck doesn't go into low gear or overdrive. Looking for suggestions. Chevrolet dealership said it was a electrical problem.

chief301,
Did the dealer give you a more specific diagnosis on what it was electrical? Is the vehicle still at the dealer? I look forward to your response.
