Which trans?

I have a 89 MJ and it has a 5 speed. I'm not sure of its has the ba-10 or the ax-15. How can I tell the difference?

I went through the same thing haha, the ba10 has a split transfer case, you can see the seam right down the middle, and it's also relatively small

Just one internal, and it's a pain to replace, it's within the bell housing (11 bolts to seperate the bell housing from the motor) it's on the drivers side

From what I've heard, I think it's a direct fit. But the ba10 (though it's kinda crappy) if you take care of it it'll treat u well, I haven't had any problems with mine knock on wood

And the ba10 is easier to drop if you doin the work on the ground. Just cause it's smaller and lighter(only plus)

I would get ahold of the ax15 and just hold on to it, tear up the ba10 then when it finally gives, just swap it out

I have a ax-15 laying around already, and my ba10 doesn't like to shift into 2nd gear all that well anymore.
