Default 85 XJ Auto transmission

So I drove my XJ on the freeway today, (took about 40 seconds to 50) and by the time I hit 55 (2 minutes later) the transmission kept going back between 3rd and 2nd gear. Much like it being unsure which gear to use.

Do I have a busted transmission? What could be the culprit? Thanks for any help.

And is there an interchangeable transmission from another car? If I have to change it, Im not sure I wanna keep the same tranny.

I think it may have a GM transmission, not the good AX4. The engine and transmission from an 85 Chevy S10 might swap over.

I guess 84-86 were bastard years for drivetrain parts. GM engine, MOPAR transmission that bolts to a GM tranny, where does Ford come in to play?
