This is the problem with vehicles and warranty claims that need to be "repaired" according to "the code".
You have a whistle and yes it could show it's got under boost or an intake leak and it could also be, a loose pipe, turbo failing, hole melted in intake, cracked egr pipe or a host of other...
For all the folks that have a failure and then want to be heard that they drove it very gently and never towed anything, that may be partly the issue! Diesels need to get up to operating temp in a timely manner and if you never plan on working it, for goodness sakes get a 3.6L gas!
Think its "lie o meter" as it's not actual oil pressure reading, just a computation of temp and engine rpm. Theres a pressure sensor that turns on the warning at around 7psi which is way too late if it loses oil at hwy speed
No codes coming up though? Egr recall done? Have you ever looked at MAP sensor? Worth clearing those periodically. These puppies like being run good and hot to keep things clean and healthy
I doubt this is trans related but likely something related to how the engine runs.
Has it been happening before it's fully warmed up? Of course can't "feel" anything in a video to properly troubleshoot
This doesn't make sense to me to have it fail because of angle without using 4wd. I'd say In 2wd that shaft is not even turning as the front axle disconnects as well as T case
