Possible chip malfunction?
 

Hello, I'm super upset right now because my 2012 3500 with 60,000 miles that I paid $52,000 for is having trouble. I've owned it for around 6 months now and just yesterday I noticed that when I'm driving up a hill, the engine tops out at 50 mph. I can press the gas pedal down to the floor as much as I want and yet the engine struggles to bust 2000 rpms and like I said top speed is 50 mph. I'm thinking of trading it in for a Ford diesel, NEW goddamnit with a goddamn WARANTEE. And hopefully this time I'll be able to drive the thing for a year or so without any issue. Anyways, I guess my question is, is this normal? Am I over-reacting? Should I just get it fixed at the dealership instead of trading it in?

Have the truck checked before getting upset & making a decision while you're mad

Take a quick look at where all the electric cables plug into the trans. Maybe loose or broken. It doe's sound like it has gone into limp mode. It is in that mode to protect the trans. But some kind of warning light should have come on.
