MiNi Beast Posted December 30, 2021 Share Posted December 30, 2021 Not sure what you talking about. Pic be easier as then I could read it better. What trans do you have ax 15 or ba-10? Link to comment Share on other sites More sharing options...
Aussiemj Posted December 30, 2021 Author Share Posted December 30, 2021 I have a ax15 Link to comment Share on other sites More sharing options...
MiNi Beast Posted December 30, 2021 Share Posted December 30, 2021 Ok. I wanna say weld it back. But in theory you should be able to swap the case with any 4wd ax 15 as the internals shall stay the same. Link to comment Share on other sites More sharing options...

I think it was just the tcase that was clocked different an xj/mj setup. Link to comment Share on other sites More sharing options...

I would certainly try that before hunting down a blown tranny and taking two of them apart nto move the rear housing over to yours. Link to comment Share on other sites More sharing options...

Any competent welding shop can repair a broken aluminum casting with the appropriate welding method and filler. The cost would probably be less than the cost of a used transmission for a case donor.
