Yeah took a couple reads, if you say "M Car" I would assume m3/5 of various years, e30 m car im assuming is an e30 m3, and no auto trannys, so this is one confused guy. The e36 tranny im pretty sure will bolt to an m20, because I know the m20 tranny (cant think of the model) will bolt to a m50/s50/s52.
