AW4 question

Of the 2 Jeeps I have owned, both were automatics with the AW4 trans... My question is, for all of the conversion kits I see on the intrawebs I have never seen an adapter plate for an AW4. Is it too light duty for other applications? If it is then what suggestions would you guys recommend for a trans swap? I can drive a manual no problem, but there seems to be a big number of different transmissions out there that Jeep has used in their XJ's. One other thing, are there transmission rebuild kits for the AW4 that would beef it up a bit if it is too light duty?

Edit: btw I am looking into 5.3l all aluminum Chevy engine swap.

Talking to an individual who had a built Toyota 4-Runner a couple of years ago, he had replaced his AW4 with an AW6 tranny. It's a beefier transmission by the same manufacturer and has the same mounting bolt pattern making it a easy swap in.

Advanced adapters probably makes one.

SO, Would an AW6 bolt up to an XJ 4.0 ?

That's what I was told. I don't know any more

Is the AW6 A 6 speed tranny?
If yes I wonder if it will improve MPG's on the XJ?

No, It's a beefier 4 speed

My mistake, on wikipedia I found the following:
The AY-6 is a 6-speed manual transmission manufactured by Aisin. It is designed for longitudinal engine applications and can handle up to 345 ft·lbf (468 N·m) of torque.

Here is some good info on the AW4
