Nice Bronco, those are rare to see in good condition.
The V6 transfer case is medium duty, the 302 Explorer has the stronger trans, and it can take the same TC's as your Bronco etc, they have the same six bolt pattern and shaft matching parts. The SOHC 4.0 is big trouble eventually, all of them, so if it is still in good shape, they can go 100-150k miles if best fluid is used, and never extended drain intervals etc. But that's not likely, most have had poor oil or too long between a few times. Hopefully that's a great buy, 32k miles is excellent.
But I'd hunt the nicest(interior and features working) condition 302 Explorer, and work with that. Those are much more reliable, at any mileage over all. Any vehicle abused will be a bad buy, so hunt one that seems well cared for.
Also, the AOD can be replaced by the electronic 4R70W, if you spend the money for a Baumann controller. The trans is very strong in 1998+ versions, and people love that controller I read a lot. Regards,
