Can a FWD transmission be converted to work with AWD

I hope this doesn't sound like a dumb question, but I have a very low mile transmission from a FWD S60 and I'm hoping I could somehow make it so a transfer case could bolt up to it and use it in an AWD car. So will it work or is there no way to convert it?

For some reasons, I thought the Trans is the same for both FWD and AWD versions?
May be I am wrong...

No. The final drive for FWD will not have the splines to drive the angle gear. The FWD case has a small opening for RH axle that i too small for the AWD collar. If the FWD trans is similar year and from a turbo engine car it will have the same internals and gearing and could be put in the AWD case and use the final drive from the AWD trans.

That's what I figured, thanks!

It is, minus the transfer case. However there are holes on the FWD for the transfer case to bolt up to. But like jimmy said, the shaft is smaller.

Is it a turbo FWD trans?

Can you just not add the AWD parts and make a FWD car?

Here is a link to a thread where a guy says he did make the conversion. He says he went from a 5 speed auto, apparently in an AWD car, to a M56 from a FWD car. It’s the last post in the thread.

Yes, both turbos.

Thanks, that's good information.
