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.

Or re-said as it were - Cruiser did mention you need to confirm the tranny model.

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

What oil filter?

First off, verify lube level and condition.
Identify which trans you have.
As with any "new to me" vehicle, check all fluids and condition right away.

Exactly at least if trans craps out it will have clean oil in motor for tow home Cruiser.
