Question: Would a 99 WJ NV242 case work? I've been searching and searching for shaft length and spline counts, but have come up empty handed. Bolting it to a 94 AX15 tranny, currently have a 249.

No speedo hole on the dubs. Easier to find a ZJ unless you want to fork out the cash for a SYE from Tom Woods. You will have no core though.

I have a 242 transfer case out of a '93 ZJ that I plan on using to replace my worn out viscous coupling 249 in my '97 ZJ. Input shaft lengths are correct, so this should be a direct swap. After cleaning all the grease and crud off the donor 242, I discovered some JB Weld around the filler hole for the transfer case. Looks like someone in the past cranked on the filler plug and cracked or broke the case around the filler plug. I don't trust this patch job and will replace the back half of the transfer case. Anyone know if I can just use my 249 back half to replace the 242 back half (not changing any internals)? I know the tail shafts are different and those unbolt and can be swapped. The only thing I want from the 249 is the back of the case.

is there some website to tell you if your TC has the new or old gear cut? My jeep is a 95 and im going to assume right now, as its too dark to check, that my TC will be made around 94.5. So is there a site that lists serial numbers of the TCs with the old cut and new cut?

I believe anything 1991 and newer is the new cut.

crawled under my jeep today and took a picture of the metal tag. Does anyone know if this has the new or old style gear cut?

I believe the code on that case shows december of 1994 so he should be safe to say its the new cut.

What is the performance like after you do the 249 to 242 swap in a I6?

lol im just busting your chops i honestly love the 4.0 May not be a beast but they are amazing engines. You will get a little bit better gas mileage and a little better performance. Dont expect the world but yes you will notice a difference. You gota fill out your profile. What year is your ZJ?
