Do we know if the 05's had a modified GM A/T??? What were BMW thinking of??? GM parts in a BMW for cripes sake!
BMW does not make its own transmissions. BMW has used GM-sourced ATs for quite sometime, and they are no more reliable or problematic than other automatics made by ZF. The automatic on a 5-series is no more reliable than one in the X3. The X3 shares its AT with the E46 3-series.

Please explain the bolded part above.......I might be able to tell you why. Kickdown refers to pushing the throttle past the resistance point. I don't see the difference between kickdown and "nailing it" ?

There was a SIB for '04-early '06 models where the 3rd or 4th gear will hold too long while going uphill. The fix is a simple software upgrade to the "hills program". I was one of the first to get the fix and it works fairly well now. I prefer the transmission to hold a bit too long, instead of not holding at all (like my mom's 325i). I live in a hilly area, and to me the gearbox works very well.
