Actually it's a wonder the 325i/328i can get away with such a light trans (they used the same one on 4cyls, lol), but I guess BMW felt it would work just fine. But obviously with 500wtq, the GS6-17BG wasn't going to last very long..

hassmaschine where did you get the 125ft/lb spec for the 328i transmission? When I did my research before modding my car and cross referenced the BMW part numbers with the Getrag website I got a much higher figure of about 258 ft/lbs.

That is very interesting that 350nm is the limit on the transmission because I just confirmed the limp mode limit is set at right around 360nm by checking the torque limit fault code data at a shop.
