I remember reading about the BMW PPK upgrade for our N54's saying that it upgraded cars with the auto trans to 450nM but the manual only upgraded to 430nM as the manual gearbox wasn't able to handle the extra torque. But then again many here with manuals have way more than 450 and aren't breaking.

I think there are quite a few different versions of the Auto Trans. The later versions can handle much more Torque than the early ones. I wanna say its klike early ones are 400ish Nm rated while later ones can handle 680Nm-ish. I think I saw that on some ZF service documents a while back while I was researching servicing my automatic trans for my e39, I ran across those ZF service docs.
These guys also have the ZF service docs online. They also sell the service kits of fluid and filter changes.
