01 cummins

truck cranks and idles perfect, but in drive when it gets to about 1900rpm, it falls flat, won't even shift out of 1st, in park or neutral you can rev as high as you want, I've replaced injection pump, checked as many electrical connections I know to check, even put it up on a jack and tried to run thru gears but it did the same thing. Any ideas would be greatly appreciated!

Does the speedometer work?
Especially below 10 mph?

No codes? Figure that one would be a crank shaft position issue. That or an APPS.
