Hello i have a 93 zj with the 4.0, 42re, np249 combo. My question for the experts is my trans is bad i found a good 96 zj with 4.0, 42re, np242 combo am i going to have any trouble swaping these two. Im going to do the trans and t-case so i dont have to gut the t-case just wondering if everything will basicly bolt right up and plug right in. Thanks for any info any and all i can get is helpful.

I think your gonna be ok. Make sure you get the torque converter and the flywheel off the other Jeep. There was a bolt pattern change on the torque converter.

Might want to see about the driveshafts as well..

OH, dont forget the transfer shifter and bezel...

And are you absolutely sure you have a 42re? The early 93's used an AW-4... easily identifiable by the 1-2 shift position.

I believe '93s used a separate TCM, but the '96s were controlled by the PCM. Will the sensors be the same?

I do have the 42re because i have the manual OD button the aw4 does not have it. as for the tcm and pcm that was my question is there going to be anything ill have to do if they are different?

I can't answer that positively. I'd think you should use the sensors that go with the vehicle. JMO though.
