Hey good too know!!! Sounds like you have confirmed figmentA 3FE one from an 80 series is a direct fit
If its a manual, there is OEM support for it.
It looks like you can get 16400-17030 online from the usual overseas part retailer crew for $600+ (with shipping). Toyodiy leads me to think that this was used on automatic HZJ81 and HDJ80 at some point. No idea how compatibility would work there.
I'm personally eying 16400-17020 for HZJ80 manuals, which you can get from US (and Canada I believe) dealerships for less. And putting in a transmission cooler, not worrying about having a radiator do temperature control on the ATF.

automaticAutomatic or manual transmission?
I assume then that the AT radiator has a loop of transmission fluid running through the normal coolant radiator, almost like a counterflow cooler? Or it's looping coolant from the radiator through the transmission?They're a heater and cooler
The trans has the ability to hit 300 degrees unchecked. The coolant is less than that, and as such they draw some heat. Because the coolant is typically in the 190s they also keep the trans fluid above a minimum.
@Dusten covered the temperatures aspect well.1) Can I confirm the radiator lines on the OE radiator for automatic transmissions is indeed a transmission warmer and not a cooler? I've seen both posted on this forum including discussions of people adding a transmission cooler when they had to switch to the MT radiator, but the discussion of it being a transmission warmer tends to come from more experienced sources. I'm pretty sure it's a warmer but would just like to triple check. And given that... I assume the OE lines are running coolant through the transmission and not transmission fluid through a second radiator hidden within the main radiator? If installing a radiator lacking the AT circuit, do you need to cap or drain the lines to the transmission, or just ignore them?
In my research on this forum, I have not found people who had installed these eBay specials in HDJ81s. You'd have to figure out all of those fitment issues yourself. Mounting to the body, fan shroud, big molded coolant hoses, transmission lines. It's virtually impossible to figure that out before you have them on hand, in my opinion. You would need drawings of these eBay specials, and the radiator you're replacing, to be sure.2) I'm not getting a good sense for direct experience with the aluminum radiators on eBay. Anyone use one of these? Here's an example, but there are dozens listed from different sellers. Many of the options appear to be the same photos overlayed with different logos and business names, so I'm assuming in reality there are only a couple manufacturers that are supplying multiple re-sellers. How many of these are true direct fits and don't require additional welding etc to mount in the car, attach the fan shroud, etc? What did you do about new hoses? I don't know how accurate these aftermarket aluminum radiators are about using the same diameter bibs or locating the hose inlets such that OEM hoses or duplicates can be used vs needing fully custom hoses.
It would be great to get some direct experience with these aluminum replacements and see if they're good alternatives. Most run in the $225-$260 range, still have the AT circuit, and might have more cooling capacity so would be a good option if there aren't too many problems. They're difficult to report on because there are so many eBay links and they seem to come and go. I'm sure the fitment problems will vary widely.
For what it's worth, I paid $360 for my OEM radiator which I knew would have good fitment, good quality, a warranty, and be able to hook up directly (other then the two issues above). Took me a bit of looking around to get that price, but then you're not saving much money versus an aftermarket aluminum one if they are really $225-600. Unless you really dislike plastic radiators it's the simple, easy route (and possibly cheapest).
Sorry, yes I do mean the OEM manual transmission one discussed in this thread: 16400-17200 for HZJ80s.I assume by OEM you mean the one for manual transmissions that's still made? This would for sure be the easiest route, but not the cheapest. If that AT circuit really does operate as a cooler as well as heater, I'd for sure need to add a separate AT cooler. I don't tow anything, at least not yet, but I live in Phoenix and my most common trips include steep grades where the ambient temperatures can be well over 110F. I don't think you could add too much cooling capacity.
I'll keep thinking about this. Those eBay aluminum radiators are intriguing and would for sure be the cheapest solution if everything lines up well, but I'm not sure I want to be the subject for that experiment. Theoretically somebody could do quite well for themselves making an all aluminum radiator that was a direct drop in and used all the same hoses (or have custom made silicons that create a drop in solution). It must exist somewhere... too many 1hd engines out there in the world that somebody didn't figure it out, so it's just a matter of identifying it. And that's the trick with all the eBay versions - no product reviews and the sources change so frequently that even if you found a review, it might not be the same unit that arrives on your doorstep.
