no speedo on my 242 transfer case
just swapped out my 249 t case with a 242 t case in my 98 jeep grand Cherokee limited with the 5.2.
Everything went better then expected. Didn't even have to change out the input shaft. They were exactly the same at .840.
Aside from the linkage not matching up, the 242 has an open slip yoke with a boot and the 249 had a case around the slip joint.
All connections except the Speedo hooked up with the same connector but there is NO hookup for my speedometer anywhere on the 242. The 249 had it in the output shaft cone.
Am I missing something?
Is there any way to bypass the speed sensor? I need to make sure there is no codes being sent as I need a New York State inspection
They I do think need a speedometer but there can be no check engine light
I believe the 242 came out of 99 grand cherokee where the speed sensor is in the transmission and not the transfer case

Old fart with a wrench
Yeah, you need a speedometer for recording the mileage at least. You can change the t/case output shaft and rear bearing cover for the earlier one and that's about the only fix. The 99 shifts by cable, not linkage, and the speed is calculated by the PCM using trans output shaft speed as well as ABS sensor feed.
You can find another 242 also.
