Hello all. I have a 2019 3500 4WD Laramie 6.7 Cummins HO dually w/ the Aisin Trans. 29K miles. I have not towed anything yet.

I'm too lazy to look through the user's guide and I don't want to be pressured by the dealership to due unnecessary maintenance. Been Googling and am I correct on the following? . . . .

The trans fluid should be changed at 30K--and then at 60K--pan dropped and filter and fluid changed?

With no severe use, gear boxes changed at 60 - 80K? I never use 4WD, only every so often just to keep the internals lubed.

And, what about the coolant? It's original. Truck was built in Oct 2019 (bought new in Jan/ 20), so it's just now 5 years old

Sound about right for my truck?

I have an extended factory warranty out to 6 years and 72K

I believe the second paragraph nixed that idea. Maybe you could read it for him :p
Was just hoping someone, from experience could advise, with regard to my personal use and history with the truck. That's all. I value advise from experience.

Yes change trans fluid at 30K even if your not towing, if your not using the dealership to do the trans service you can lower your cost using Mobile 3309 ATF (see photo below of trans tag, fyi many hot shot truckers use Mobile ATF 3309 when they service there trans) your coolant is good for 10 years or 150K, my owners manual shows to change 4x4 transfer case fluid at 48 months or 60K...
