I have an 07 328i automatic with 48k miles I bought a year ago as a CPO car. I planned to do a partial fluid change today, with a new ca$e of Pento$in ATF1 $itting at the ready. Having done this type thing more than a few times in other cars, I scoped out where I was going to put the new fluid in before draining the old.
Unfortunately, the trans in my car looks nothing like the one in the DIY guide here. The typical 17 mm internal Allen socket plug was nowhere to be found. I can see what is probably a black filler plug at the rear of the unit (a protruding, mostly-round-with-two-flat-sides type), but it is mostly blocked by the rear mounting bracket for the trans.
The impression I get is that BMW, like so many other manufacturers, has marched one step further towards making these cars unmaintainable by the home mechanic, even compared to the generation car in the DIY. I can see getting this done by perhaps supporting the trans from below the car, and disconnecting the rear support structure. But man, it shouldn't be this hard. Any constructive thoughts?

transmission on n54 engine does require to be on certain temperture to be leveled properly. to do so, you will want/need to hook it up on the machine. so yea, i wouldn't attempt to do this at home. few european specific mechanic shops have it as well as dealers...
