2004 F350 FX4 ext cab 6.0 diesel torque shift speeds up while driving and at stop lights on its own. (once while backing) my dad will not ride in it any more and claims I am crazy for driving it. Harsh trans lock up at 45 after auto trans was dropped and updated with planetary bulletin at dealer. The trans deal I will continue fighting, but the mind of its own in acceleration is dangerous. Am currently packing a dealer computer with a panic button but have not caught the gremlin yet as it will go for a while in between uproars. I feel jilted being a test rat after buying a vehicle with a $46,000 sticker price. And then there is safety. Will take the truck back tomorrow and tell the associate to pull the computer and wires and the next time he sees me will be with the truck on a hook or me alone with a lawyer after an accident. I know their trying, but the lack of trouble codes as well as the inability to repair the vehicle without them could be the end of someone?S life and or the destruction of property. (time at dealer so far aprox 2.5 weeks off and on)

When truck was put in gear, the transmission would not go in gear. Also, when driving, I let off of the gas pedal, truck would stall, and then engage and then lurch forward, in traffic. Also, same problem in reverse.
