SO I just flew into Dallas this morning and i told my wife she could drive my truck while im away. I put my truck back to stock and gave her the keys she called me about two hours later and said that she drove twenty miles and she noticed that the factory tranny gauge was in the red and the tow haul light was flashing she also said there was a check engine light on. I am not going to be home to check codes or tranny fluid level. I also told her to drive the truck back home later today and watch my tranny gauge on my piller since it would be accurate. Does anyone know what this could be i have never had any problem with this truck and I pull my 10k all over the country so why would i have problems now on the stock tuning
any help is very much appreciated thanks guys.
