I have a 2007 S6. We are planning a bunch of work on the car. One of the things that I wondered, is a 6speed swap possible?

I did a little research, and thought that an RS4 transmission might work. But then, looking at it closer, and comparing to the S6/S8 gearbox, the front axle is too far rearward on the RS4 trans, and almost every other manual Audi offers. The S6/S8 transmission has the front axle pushed right up to the front of the gearbox. The only other manual transmission I could find with a similar layout seems to be the 6speed from the S5.

However, the bolt holes dont seem to line up with the S5 transmission, from what I can tell with pics, anyway. I am not sure if you could mount it up with an adapter plate, or if enough of the holes line up to make it work.

So, has anyone tried to convert the v10 S6, or even v10 RS6, to a manual? If so, please provide any details that you have.

Thanks!!!!
