I ordered MT90 from Amazon. I'm not familiar with the BA-10 tranny (so check out the fluid change procedure) but almost certainly you will want a fluid transfer pump.
Cruiser may be able to advise if MT90 (or in other words, low sulfer gear oil) is the recommended fluid for the BA-10. A quick Google search shows folks divided on GL3 gear oil (which MT90 would be good for) and Motor oil. (To be fair, when I looked into fluid recommendations for my AX15 there were people recommending motor oil for it.)
A critical point that needs to be said is that you need to verify the model transmission you have. The BA-10 has been a maligned transmission in Jeeps and a PO may have swapped it out for an AX15 or (unlikely but not impossibly) an NV3550.

Just finished the oil, went with 10-40 and some stabil. Also replaced the oil cap and now my pressure is stable at 30 psi idle and 35-40 while driving. Old oil was pitch black haha. Going to look more into trans this weekend. Anyone know where to buy the mt90 fluid? Autozone didn’t carry it and I’d rather buy it in person than online
