I need to get an smg put on my 2002 bmw m3 manual, hurt my left knee and i can't shift - have to keep my car. I went to bmw in santa monica, california, they said they can't put it on - yet i read it's in the bmw manual. Has anyone in or near Santa Monica, Ca had one put on their m3? thank you.

You can't simply just put a SMG onto a manual transmission car. They are completely separate transmissions. Thus, in order to change your car from a manual into a SMG you would have to completely swap out your transmission which is a very expensive process. Transmission work in general can be quite pricey.

Your best bet if you need to swap from a manual to a SMG is to either find someone with a SMG that would like to swap, assuming you have comparable options to each other... OR to simply just sell your current M3 and buy a SMG M3. Selling your current and buying a used M3 is definately going to end up a cheaper process for you than keeping the same car and ripping out it's original transmission.

Btw, I've seen late model e46 M3's go for around $34k if you look on e-bay and such. So you have plenty of options to go after in looking for a used M3. Also, assuming that the M-DCT is released with the US launch of the e92/e90 M3 you could just trade in your e46 M3 for a M-DCT e9X M3.

Add to that the software issues of the engine control unit and transmission control unit (may be integrated with the ECU). When you have an automated manual of any type the engine and transmission get intertwined in a fairly complex way. What this means practically is new software and or hardware is required as well. Not impossible, just adds the price and complexity.

Well, anything is possible. The point is more that it is just extremely impractical.
