I'm a grading contractor but an amateur mechanic. While I can service stuff and replace stuff, I don't have an intricate knowledge of these systems. I appreciate the input.

Welcome to the best place on the internet in my opinion!
You can walk out stripped plugs with an air hammer and a sharp chisel bit. Just a handy tip to keep in your back pocket.
buy an extractor, you will use it for many things. They are great for pulling fuel through filters, just to name one.
It will be sound with an extra gallon in it.Don’t worry
The old D8H manual said to over fill the transmission bevel gear compartment with 3 gallons when working on a hill, like mentioned above. Also a D7F needed extra as well, a wild ride one time reminded me of that.Yeah sure didn't want to be on high rock shoving over a shear cliff edge without that extra oil.
Theoretically speaking, what harm could be done if the transmission, or other places where there is a lot of room for oil to expand? More heat?I understand what the problems would be with the engine or the final gear ...I most often fill oil a little above normal.
The transmission basically has an open top. No problems until the oil comes out the breather.You don't want to over fill engines because is the crank throws get into the oil fluid it all turns to foam and can actually starve the engine oil pump.Overfull final drive will get very hot as there is only so much room for gears and fluid to move around it.

IIRC they are a small mushroom-shaped metal breather about 2” across screwed into the top of the rear case of the machine pretty much directly under the operator seat. Dirt falling through cracks in the cab floor lands right in that area. I’ve seen instances where the breather was completely buried in dirt.

The factory mounted the trans. breather in a hidden low spot on the top of the converter housing where you could not see it and it was protected on three side so the dirt could build up real good! Pull drain plug and oil just dribbled out unless you removed the filler cap.Fixed them with about three feet of 3/8 push-loc hose and some fittings. mounted them up nice and easy to see and wash off. Still made it a habit at oil change time to remove and flush out.
Breathers never get checked unless something is wrong or some part of the machine is being repaired and the breather happens to get uncovered and someone asks what it is and what it does.

I can somewhat understand a D6 having a bunch of crap in belly pan but the rear pan of a front end loader? What part of front end loader did the operator not understand? And yes at least one of the oil cooler lines was rusted out from being buried in that wet stone for years!
There’s a D8T breather being washed out at Christmas this year.I do them when tranny oil gets changed.The earlier D8K’s and H’s had them stuffed under the fuel tank at the back.They were designed perfectly to be burried in layers of dust in the summer,that would get muddy in the rain,then dry out to a nice concrete.In those days I only cleaned them out when I adjusted the brakes and found them there!!These days,I’ve learned to read the operators manual!
Sorry,wrong pic
Not sure what’s going on here with the pics.I’ve definitely not tried to post all those pics.But you get the jyst of the little breather things.It doesn’t take a lot to block them and even less to clean them
Yeah, I was going to say that D8T ain't gonna push much with those semi-smooth tires on it...When I was a young'un I worked for a man who absolutely insisted any truck or machine that came through the shop had as a minimum all axle and tranny breathers wiped with a rag, or whatever was needed. He would randomly check behind you, and said it had really cut down on seal replacements over his career.
