4age auto idea?

You need to help me people.
I had these thoughts about using my 4AGE tvis fwd complete with ecu & loom etc for another project.
I was thinking about another ae82.
My question is can you mate up a 4age to an auto box without any problems?
Theoretically i cant see it being too much of a problem.
The ECU shouldnt have anything to do with the gearbox.
My concern is the driveshafts whether they are all the same on ae82 carby and twincam models. Also whether the driveshafts are the same with auto and manual ae82.
You may be thinking why the heck am i contemplating an auto box.
Well, its for my sis who refuses to learn manual.
Could i still use the 4age 8 bolt flywheel on the autobox???
i think 4ac uses 6 bolt flywheel.
would the torque convertor be a problem?
im not too familiar with automatic transmissions.
so any advice is much appreciated.

My AW11 runs an auto box and if I change the computer over to another 4age computer my auto wont change by itself.I diddnt think that the computer would control it but it does ( but that might be just mine!?)

thanks for the input.
I have access to an ae82 4ac auto, but it is still in use atm.
I mite try to hook it up to the auto box.
i'll let u know what happens.
Does anyone know whether the 4age ae82 driveshafts are same as the carby 4ac ae82 ones ???

ok the computer question depends on if it is an e;ectrinoc auto or a pressure driven trimatic or something. If it is electric then, chances are, the comp tells it what to do, also, with the flywheel, you'll need to get a flex plate onto it so unless you want to swap the crank, you'll need an 8 bolt flex plate, and a torque converter that bolts to it.

I have an AE82 FXGT withe the blue top 4AGE. it actually has a factory automatic box in it. its a pretty good set up, if ya like autos. it has manual over ride, so, basiclaly u can drive it like a tiptronic and it will stay in the gear u have selected untill u change.
if your in NZ feel free to come have a look, you can buy the whole setup, loom, box, engine if you want, im in the middle of converting to either a 4AGZE or 3SGE (cant go turbo, insurance is toooo high)
and yes. aparently the ECU is diferent for manuals and autos. also, the driveshafts are diferent and i think there are a few other little technicalities aswell...not too sure on that tho. the engine bay has HEAPS more wires than a manual because it is an electronically controlled system
