The heat shield(s) are removed first. They are nutted on double ended studs doubling as pan bolts. There are two pieces, right and left. The service manual instructions I read said to leave the shields off until you get the hot level correct, then re-install them.

I am always "helping" the 10 speed "do the right thing"...lol Living in the mountains running 3.73 gears on 35" tall tires just empty runs to Grand Junction I have a few hills I drop to 8th, otherwise the trans waits and ends up in 6th. I can avoid a lot of unnecessary shifting by using the transmission "features" whether it be manual mode or locking out some higher gears. I also like Tow/haul going uphill but generally not down. I love that sand/snow shuts of the nannies and runs lower gears when I have sleds to pull up the mountain on unplowed USFS roads.
I still think you are planning too much maintenance but if you go that route first change would be to a pan with a drain plug.

Thanks for the info. My take is I am a bit too aggressive on my ongoing PM schedule thinking. My problem is not how many miles driven, it is time. At 3-5000 miles a year and being parked with limited use during salty winter it is difficult for me to go by miles. I will somewhat stick to my routine, get a clean filter in the tranny this winter at the 5000 mile range along with exchange rear end oil. This will be a winter project for me where I can take my time and go slow with it all.
From then on with low mile use sitting more than driving is where I get to overthinking. Time is not addressed much in owener man and I have always been under impression once an oil is heated to its limit it is degraded with a clock is ticking. Plus I worry about condensation even stored in a unheated garage.
In regards to time all I see addressed by the manual is
3 years for brake fluid exchange.
10 years for coolant or 200,000 miles, then every 5yr or 100,000 miles.
My truck/camper is my hobby and keeping them squared aware to my standard is fun for me I enjoy it. PM on them is what I do for fun, heck I am so freaking goofy that I wax and treat the underbellys of them.

I agree and so does my mechanic, friends and family thinks that I am a complete nut on my truck and camper maint. I can not help it but it sure makes me smile knowing my fluids are new fresh and clean.

If you primarily use the truck one way then pick an hour interval you want to change fluids at. If you use the truck under mixed conditions then sending out samples of the fluid for testing is the only way to reveal if youre changing too early, on time, or too late.
My personal fleet trucks id do 150 hour oil change, 1,500 hour transmission pan drop, 3,000 hour differential and transfercase, 4,500 hour coolant and power steering, and brake fluid was changed when I did brakes usually within 4,000-5,000 hours.

Using hours is tough too. My 02 Chevy only has 2200 hours and 102,000?.

Hours works well if the truck stays hooked to the trailer and primarily is only used for that task under consistently the same conditions. Both hours and mileage intervals when the vehicles use is varied are just as random of one another. You can at least set a baseline under consistent use cases. Youll always have too much variable otherwise and nothing accurate for a true life of the oil/fluid change interval.

I’m at 211k on my 2017 F350 DRW following Ford’s heavy/abusive use maintenance schedule. The truck spends 90% of its life pulling 15k+ gooseneck trailer, with a fair amount of that in pretty rugged off road use. It’s doing just fine.
I’m picking up the 2024 F350 DRW I ordered next week, and expect to do the same with it.

mine too. I change all my fluids beyond oil every 25k miles. The tranny fluid looks and smells horrible when ever I change it. Especially if you use tow husk or engine braking. If you don’t use these features…I wouldn’t worry about it for 50k to 75k miles.
that’s just me…to each there own.
