AW4 to ax15 swap

I have done a lot of homework and it should work good but just wanna put the idea out for inspection. I have a 2000 XJ 4.0 auto (AW4 I believe). I want to swap in an AX15 Terminator. I know its a lot but I prefer driving standard that much. I know the NV3550 is ment for the 2000/2001 and the AX15 went in the 99. But it should be fine cause the 99 and the 2000 has the same engine except for the distributerless ignition and the same body. Unless there is a difference in the interior and something will be in the way of the shifter. This rig is my DD and only will see light to moderate trails. I don't want to use the NV3550. It seems to have inherent grinding, popping, general loudness issues. Any thoughts?

I have owned Jeeps with both trannys and they are both good. I will say the AX-15 did shift nicer. Id have no problem running either. Will you be getting a PCM from a manual trans XJ .

That is one aspect I haven't thought out. I thought I just needed to rewire the neutral safty switch. Do I need to change the PCM?

You will get check engine lights for Torque converter and not showing what gear its in. Also no backup lights . The correct PCM and trans wiring harness will make the job easier and better. Buying a quality trans is a wise decision. You dont want to be needlessly bothered by problems. Be sure to use a bellhousing that has an exterior throw out bearing slave cylinder.

make sure you get a 2000 and up 5 speed PCM, i've wondered but havent looked into seeing if a PCM from a TJ would work, as there are more 5 speed tj's out there than 00-01 XJ's

Yeah I'll have to check too. I wonder if the pcm and any wiring is tranny specific cause the default 2000 5speed is NV3550 and I want to put in the AX15 terminator. I shouldb't have a problem with the bell housing
