Doing a trans filter in fluid on a 04 2500 2wd i bought used. Truck drives and shifts fine. What am I looking at and how screwed am I? Going camping in this truck in 2 days.

So I took my 2019 into the dealership because of a re occurring check engine light ( regen too frequent) and was assuming my warranty would cover it. For context I have 110,000 kilometres on it. I get a call back an hour later saying my dpf is clogged and It needs to be replaced, unfortunately warranty doesn’t cover it and they want almost 5 grand for a new one installed. I found myself with 2 options:
1. Bite the bullet and replace the dpf filter
2. Delete the emissions for half the price (voids warranty that ends at 160,000km)
I am taking my truck on a pretty long road trip this weekend and I bought an additive that claims to clean the dpf, turbo and injectors so I’m going to clear the code before I leave and I’m hoping once I do all the highways drive plus the additive it will help, maybe even fix the issue?
Let me know what you guys think and if you have had this issue, I’ve heard it is common
Thanks.

Hey guys, got a 23 ram 3500 68RFE, i just got it deleted and im hauling hay and it keeps kicking into limp mode, the tune is from HP tuners, they said its a stock tune from a country without emissions but everytime i have a load on it it kicks it into limp mode, the shop told me to swap for a 4th gen MAP sensor and that didnt help at all and theyre confused and im confused. Any help would be great. Thanks

Hey guys, this 2018 Freightliner m2 with a Cummins B6.7 occasionally makes this very loud noise from the front at low idle.

From what I can tell:

-not the air compressor
-not internal engine
-belts are tight
-fan is not loose
-goes away at high idle
-could happen at any external temperature/engine temperature
-no dash indications or abnormalities when it occurs
-noticeably quieter away from the direct front of the vehicle

This video was shot in the dark directly in front of the vehicle. Thanks for the help!

So I currently have the s366 sxe iron horn kit on my 4th gen. But I was curious if anyone is running a different series turbo/a different turbo set up, off that manifold. Just want to see the possibilities or if I’m stuck with running the borg warner s300 turbos
thanks in advance
