All right so to start off his truck only has 60,000 miles on it so not very many to be having transmission issues. When you drive the truck it up shift perfectly but when you slow down it down shift into 3rd gear and stays in that gear and will not upshift and will not downshift until you pull over and reset the truck by turning on and off the key three times but when you do that it runs to the code but there are no codes for the transmission issue. We would appreciate any advice you guys may have we are struggling trying to find the issue and the Dodge dealership near us is very unhelpful and the Dodge company does not have a technical support line. Thanks for the advice.
