YJ 4.2 BA10/AX15 Swap

I have finally given up on my Peugeot BA10 and picked up an AX15 with an NP231 which I am attempting to install. My problem is, I believe have all the bolts off the bell housing on the BA10, but it just won't come off. I have gone over and over the bell housing by touch and sight and I believe every bolt is out of there, but still no luck. I have tried sticking a screwdriver between the block and housing, however there are very few spots that you can really pry on. In looking at the top of the bell housing from the engine compartment, it appears there is a small gap opening up, but no such gap is showing on the sides or bottom. Has anyone ever had this kind of problem separating these pieces, or is it just me? Should I just keep wiggling it and prying? I have tried raising and lowering the tranny jack to see if that would work it loose, but no success. I did see a website that referred to two torx bolts that had to come off the housing, however I found none. But I believe two bolts near the top of the housing were missing when I began. Anyone have any suggestions? Thanks a lot.

1. Why the swap?
2. There should be 2 torx if not you might have a problem.
When I did transmission work it was a lot of wiggling and prying.

If you are sure those two upper bolts are off, and all your mounts/Tcase are free....then it's probably just an tilt binding it up at the pilot bushing. Keep moving it slightly to find the right angle & it should come free.

The BA10 reverse was going and 4wheel low was not working so I figured I would try a swap since I have heard the AX15 and NP231 were a lot better. There were definitely no torx bolts, but I am pretty sure the top two bolts weren't even there so perhaps a previous owner removed and never replaced them. I believe it is hanging up on the two guides that are within bolt holes on either side near the bottom. I guess I'll just keep wiggling and prying. Thanks.

My first jeep Cherokee.
Had that combination. Great great setup.
but trasmssions never come out easy. Lots of wiggling and prying. And maybe a beer or two.
