As far as I am aware the key difference was the size of the torque converter but it's more difficult than that as you need more than just the torque converter you need the flex plate and bell housing too, the volume and flow of the oil pump will define your changes unless you are using an ECU controlled gearbox of course.

What are you trying to do exactly?

apart from bell housing the difference is valve block, if you change both you have either box, petrol and diesel need different valve blocks to suit gear change, you can run either but its crap

Think outside, no box required.

Don't know what the OP's vehicle is but someone I know has a Defender running a 300ti/auto & it goes quite well, although not the same as a V8/auto obviously.
