When I was looking up some of the fluid ideas/options one thing that came up is that some people have added an aftermarket transmission cooler - basically a pump and a heat exchanger for the fluid. I think if I was worried about temp enough to downshift for temperature I would probably do that.
Yeah mine got hot due to that design flaw of sixth not getting enough splash cooling and circulation plus just towing really heavy.
I had the MagHytec (so?) larger trans covers with bigger fins that folks reported mixed reports on whether or not they kept things cooler but they also added something like another quart of fluid capacity as I recall. They also had magnetic drain plugs so if the trans was ever making any metal it would be stuck to the magnet on the inside of the drain plug when you pulled it to change the fluid. All put on by the original owner but seemed like reasonable upgrades and not gimmicky.

TPMS would be a good idea on the trailer (or in general). I've had two trailer tires blowout in my history, not enough to make me care now, but if I started towing more regularly again I would probably add it.
As to towing speeds... well... I'll just keep my mouth shut.

I found it interesting that tire pressures were always higher on the sunny (usually south) side of the trailer by a fairly large number. Made sense after you see it, but was surprising on the first trip.
I used the external ones screwed on to the valve stems. I ended up not liking them. If I used those in the future I would put in steel valve stems.
They make internal ones with an integrated valve stem and those make more sense but cost a bit more and usually aren’t stocked anywhere. And of course your tire folks have to install them.
I would go that route if I did another big trailer. Too easy for a rock or something to maybe knock one of the externals off and lose tire pressure after ripping a valve stem off.
But they worked. I was just always worried about the stress they put on the valve stems.
Of course the other downside of the internal ones is having to unmount the tires when the batteries fail.
Also if the trailer is reeeeealy long they made a repeater/transmitter that could be wired into the trailer coach power or wherever you could get 12VDC somewhere near the front of the trailer to repeat the weak signal from the TPMS sensors to the little receiver on the dash of the truck.
I never installed the one that came with mine, they all reached the cab and never dropped out, so that device would have been one more thing to remember to switch off in the post-towing checklist to not kill the coach batteries.
I had installed four 75 AH data center high current deep cycle batteries I had and taken out the stupid little consumer deep cycle that came with the trailer, but still.
No need for vampire loads on all the time, so it would have been installed with a switch which would have been installed in the coach’s switch panel.
Once I found they reached the cab, it sounded like a whole lot less work to not install the repeater transmitter. Ha.
