I see the 2.48.1, however there is no mention of this being applied to the 335d transmission.

these is nothing about E90 in this document.... and the software for the gearbox was available since August 2012 (ISTAP 2.47)
I have never checked, but I dont believe there was any recall for the 335d gearbox in the past. This is like with any other modules -BMW release new data files, but they dont call each time BMW owners to do the update, unless it is necessary. Also dealers dont like to play with electronic. When something is working, great, they will not update anything if headquarter tell dealers to do so.
I just did this update, notice big difference, sharing here on the forum and recommend to anyone who has a chance to do it.
