Awhile back some E70 owners were discussing issues regarding the transmission during shifts. Does anyone know if a BMW service information bulletin (SIB) is out on this? Got an appt with the dealer this week for another issue (headlight washers quit) and they're clueless if I don't hand them something in writing. Thanks!
