Help! Truck won't rev over 2000 rpm

So I was driving home and my truck started slowing down and wouldnt rev over 2000 rpm and won't up shift. Temp is fine and so is everything else. What is wrong with my truck? I have a PPE tune level 2.

yeah you limped her, put your ppe on there, tune it down a level and clear codes. when you turn her back on, she should be fine. If there's no code or all what i said earlier didnt help any, you might have a nsbu problem. but lets see what happens before we go that far...

No codes no lights nothing. I was driving down the highway at 65 when it happened. I didn't gun it at all today, I was just driving home from work on level 2.

when was the last time you changed your fuel filter?

and scan it anyways to make sure you dont have any codes - your CEL may not work

The fuel filter was changed 2000 miles ago. Just scanned it and there are no codes.

Yes it does. Everything works and looks normal as far as tell. The truck will start right up but just won't rev over 2k. Actually it stops at like 1800 rpm

Start with a new fuel filter-- if the trans is in Limp mode-- it will set a code.
