Wrangler 231 Cherokee 231?

I might be beating a dead horse but i searched a little to find out if a wrangler 231 is any different than a cherokee 231. I seen 2 different answers. Will a 99 wrangler 231 directly bolt in to my 96 xj automatic? If not what is the difference?

What trans on the donor.I know the auto's(they dont use AW4's) have the long input shaft(t-case side) and dont fit.

Yeah its coming form an automatic. guess it might not work after all

I thought they were the same...? Maybe different year Wranglers (TJ, YJ) had different Tcases?

A 99 Wrangler is a TJ, which uses a floor-mounted transfer case shifter similar to an XJ. The earlier YJ Wranglers had the transfer case shifter mounted directly to the case. The YJ transfer cases were "clocked" (oriented) slightly differently from XJ transfer cases, which made using a YJ case in an XJ not a direct swap.

But I do not know if that's true for the TJ Wranglers. I suspect that, because they use a floor-mounted shifter, they might be clocked the same as the XJs.
