1989 transmission replacement

I have an 1989 wrangler YJ, 4.2l, with 5 speed manual. The transmission has about had it. What I am wondering is what transmissions will interchange.. I.e. from other makes, models or years. I'm not really sure exactly what Trans I currently have just know its either going to need rebuilt or replaced soon and trying to find out what options I got here. Also if a rebuild or replacement would be better/ better on the wallet.

you have either a Puegot BA-10 if manufacture date prior to march 89, or an Aisin AX-15 if after. Do a search, there is a thread that shows the differences, pretty easy to distinguish. If you have an AX-15 they are readily rebuildable, or you can get another AX-15 from a wrangler, cherokee (you may need to reclock the transfer case) toyota truck. Take a look at the sticky threads under Frequently Asked Questions and there are threads that will explain the conversion process if you need to change your input splines on the transfer case

I think the exact date for the AX-15 being out into the YJ's is 10 March 1989. go to the Novak website and they have pictures and some info on both.
