Manual to auto swap?
I'm mainly just curious, but has anyone done a manual to auto swap on a jk and or is it possible? Would the computer have a cow or would it accept it?

As far as the reflash, does that mean the opposite is true and if I want to go manual I just need the physical equipment and then have someone flash the ECU? Is that something the dealer would have to do? My local dealer has monkeys working in the back that I wouldn't trust to make a PBNJ sandwich.

5 speed automatic?
Yep, I have a question about automatics but this thread is giving me a clue. I wasn't impressed with the auto JK and bought the 6spd man... but I was curious if there were any good automatics that could be swapped into it.

this has been brought up in the past and there would be allot more involved. allot of the wiring has to be changed as well as a ton of other stuff, it gets to the point where it wouldn't be worth it. swapping to a manual while doing a HEMI is only "easy" because your pulling all the crap out anyway

unless someone has a heavily modified rig already it seems more cost effective to just sell and go out and get an auto equipped unit...
there are so many factors to deal with though in trying to install an auto not made for the JK to the original engine..
will it mate to the engine?
is there software for the computer to run it? the stock PCM drives a 4 speed auto.. where would the routine calls in the software be for a 5 speed auto? would require complete custom PCM build..
tailshaft length and whether it will mate to the transfer case...
width of the bell and the trans itself...
lots and lots of factors to do the swap in a Modern vehicle...
not like doing it in an older vehicle where it was just a matter of cutting , bending, and welding to make it fit...
the software factor is tough... I have done a lot of ECM / PCM hacking over the years. but I wouldnt want to have to add complete routines to drive another gear effectively...

Just got a smoking deal on a automatic tranny w/ 20k miles on it. The torque coverter, housing extension, dip stick, isolator block, and crossmember mount were included. When I get the rest of the parts together I'll begin the "show and tell" thread so I can put all the doubt about a manual-auto swap to rest.
