Thanks for the info on the M and +/- guys, mine sorta did something similar over the weekend pulling the trailer. I was able to get
it to upshift by hitting the throttle. I also used M for the first time, locked it in 5th for a couple of hills. It held 65 instead
of going from 6 to 5 to 4 all the time.

There's probably not too many people with that many miles on their trucks yet. 4 years old for an early 2017, would be about 37k+ miles a year.
The '11-'16 guys would be the ones to ask.
I just hit 20k on my truck, and I'll probably change it around the 75-80k mark...

I did fluid exchange at 50,000 .... also did both diffs, trans case, brake fluid flush, etc. ....... 2017 6.2L
I will do the same at 100,000 and 150,000. Nothing wrong with some fresh fluids..
Changed plugs and tires at 80,000.
Will do brakes at 90000/100000..... we'll see.

I find it odd that the trans doesn’t have a shorter interval listed in the “Special Operation Conditions” section. I’d figure 150,000 for normal and maybe 75,000 for special. I guess since Mercon LV is synthetic, it lasts forever! I figure I’ll try the 150,000 and see how it goes. Unless the color or smell tells me it’s time to do it sooner!

Our company trucks run well past 200k without a trans fluid change. We have 10 speeds in f150s past 175k with no issues. Cj

I am aware of that but thanks. My 'issue' is trying to keep the truck from dropping into 4th all the time on inclines that I think it could/should hold fine in 5th.

No way will I wait for 150K, my plan is swapping out oil pan for one with a drain, changing the filter and fluid at 30K then just doing periodic fluid drain. I have a had time believing the fluid is good for 150K?

I think the trans fluid is capable of going much farther 150K (sold my highlander with 300K and I never touched the trans fluid). My oil can also go much farther than the 9K + that I run but I choose to not go beyond that (thinking of shortening to 7.5 - 8K).
I did a drain, filter replacement and refill on my trans at 60K. Now that I'm at 90K, I plan on a drain and refill. I might send some off for testing just for curiosity.

If you ask me thats crazy and anybody that does it especially if they tow a lot is nuts for following that. I do 50 on everything under the truck but Im a maintenance freak but all my stuff last and when I get rid of something everybody that likes used stuff wants it.

By more throttle than you would expect it's really way, way, way more throttle than you would expect.
