I'm pretty sure you can't use your factory transmission with the hemi.

the pentstar transmission is the same transmission used in the newer 5.7 and 6.4. just cant be used with the engines that run the 8speed auto

Ah could be. I only know people with the old motor doing the swap. Carry on.

You know IF you have time and a camera,
It would be real nice of you to do a write up on this project. I know a lot of us would be very interested in what all it takes to make it work.
The computer part is what really scares me.
Where are you thinking of sourcing you motor from? Like a local wrecking yard or trying to find a good deal on a used car/ truck?
This article over at Allpar has a lot of good info about this differences between the Hemi's.

plan to source the engine from a salvage yard or ebay which ever place i can get the best deal. there are a few good write ups out there that i plan to use myself so it may be a little redundant. the computer and wiring harness and programmer are part of the conversion kit.

One thing you may want to do if you have the cash to do a 6.4l swap is to upgrade the tranny internals. Yes it is a W5A580 but some of the internals aren't the same as used on the SRT vehicles with the 6.4L. You will definitely need to do the torque converter but there are lots of upgrades available for the tranny. It is the same basic NAG1 that Mercedes uses in the AMG vehicles too but again they use different clutch packs, solenoids, etc. do a quick google search and you can find all that's out there.
Also, if possible pull the 6.4L from a WK. the headers and oil pan setup are what you want. If you pull from a 300, Challenger or Charger will need those too. If you look on AEVs website they just released their 6.4L kit for the 2012-2014s and have great instructions and a complete list of all the parts you need. I'm surprised they list it there actually since anyone can download the instructions.

I edited too late. Best bet is pull from a WK SRT. It's oil pan is set up for the front diff on a WK so it's how you want it. The car version oil pan won't work for the JK.

Didn't someone already post up that it should be from a SRT WK?
