Fugg...that seems like a LOT of work just for a SSK! Definately a major job as it seems that without a lift it would be a PITA job! Definately NOT a regular home garage DIY job for you an a buddy with a case of beers IMHO! LOL If I did it...I just "pay the man" and get a shop to do it right as it seems there's lots of places to mess up your transmission in this install and I am sure BMWNA ain't gonna cry with you when warranty issues come up for a botched job!
