So I am having trouble with my truck right now. When I try to jump on it, my truck "falls flat on its face" like its hitting a rev limiter. When it does this, it is popping up a "Service 4WD" message on the DIC and is flashing a check engine light that only flashes a few times and then goes out.

This just started happening after I did the installation of a bunch of after market parts (check mods in signature).

So far I have scanned it with a few items (including a tech 2) and here are the following codes I have received over time (not all at once and not in any order):

-C0569
-P0606
-P0561
-U0102
-U0140
-U0141

So far I have tried the Manual Relearn For the TCCM using the 4WD selector switch, but it didn't work. I have also taking it to a shop and they couldn't tell me anything, but diesels weren't their specialty either.

I have attached a datalog for reference, if that might help diagnose it better.

PLEASE HELP!!!! I have a ton of money into this truck and I have yet to feel the true potential of this beast due to this issue!
